Jan would have been 73 years old, going on 74. His life was cut too short unfortunately.
If I did not reschedule the lunch with him, I would have found out his health condition and maybe he is still alive today.
Looking at his photos, he was really handsome when he was young. You can tell he was truly happy when he spent his summers in Sweden.
It would be nice if he were still alive. He is gone.
Luckily, he has a smart and good-looking son. Erik bears some resemblence to Jan. Jan, I miss you! You shall not be forgotten. A very unique person!

I knew Jan since February 2017. He came to the open house that I was hosting in his complex. Because my husband is Dutch, we had quite a bit to talk about. We went to Hollister several times to see if we could find him a dream home with acreage. I got to know Jan much more during those trips.
Jan was an honest person; he had integrity. He was smart and logical. I could see Jan being a good manager – He had the ability to manage. He was loyal to his friends.
Jan was immaculate; his home, so clean. I was amazed that he did not feel lonely. He could keep himself occupied and entertained. He had to have great genes! Jan was old-fashioned; he kept his Swedish furniture in pristine condition. He maintained his car like new; he was also a good driver. He was proud that he had not seen his doctor for ages. He was so smart that he enjoyed fighting with the Homeowner Association for his cause.
I had no idea how he spent his summers in Sweden until I see the photos here! It was a good life! Jan, I am sure you had no regret! I just wish you were still here with us! The world is darker without you! May you Rest in Peace!

Jan Brunnberg - In Memoriam
I have had the pleasure to work closely with Jan for many years at Power Integrations from the early beginnings of the company where we first met. We both shared the passion for electronics and I owe him a great deal of technical knowledge that he, as an accomplished engineer, has taught me over the years.
Jan enjoyed his work a lot, being careful about minute details, always improving his test programs. I was a younger engineer and his attitude towards work also inspired me to build better hardware for his increasingly complicated work projects. We enjoyed working together and he started being a mentor to me and later we became friends.
We kept in touch often after each of us went on our separate ways, outside Power Integrations. We frequently spoke on the phone at length, about technical matters and also our lives, passions and future plans. He also helped me on several occasions with personal matters, for which I will always remember him fondly.
Jan was the first one who introduced me to Thai food and we had a blast that first day for lunch at Thai Basil, a small restaurant on Murphy Avenue in Sunnyvale, CA. I was not used to eat spicy foods at all, but we both ordered an extra spicy Thai Panang Curry and it turned out he was not able to finish it for it was too spicy even for him. Later, we would meet for lunch many more times during the years and always laughed when we remembered that first day at Thai Basil.
I was looking forward to meet with him again as soon as possible this time in Europe, since he would spend several months a year in Sweden, so I received the news of his untimely passing away with shock and great sorrow.
Jan, you were my friend and I will miss you. May your soul rest in peace! Inte Klok.

Life of Jan

Jan was born on May 8th, 1948 in Bromma, Stockholm. He was the younger of two boys who went on to complete his electrical engineering degree. In 1969, he began his career as a test engineer at Ericsson in Sweden.  Jan spent some time in Texas before moving to California where he joined Power Integrations in 1989 as the first test engineer in the company.   He spent the next 25 years doing what he loved at Power Integrations and mentoring many engineers along the way. He was happiest when he was on the tester or remote logging into the tester from his office.  During the latter part of his career, he decided to spend 3 to 4 month each year in Sweden caring for his ailing mother. Jan retired from Power Integrations in 2015 after 25 years of service. In his retirement, Jan would extend his stay in Sweden for up to 6 months per year.  He enjoyed driving to San Francisco for leisurely day trip, got his daily exercise by walking to Fry’s Electronic (Jan’s favorite store) and was in the process of searching for a sizable home away from the buzzling Silicon Valley where he would be a few acres away from his closest neighbor and there would not be any traffic when he needs to go to Safeway.  He also enjoyed watching movies after his retirement.

The descendant of Jan is Erik Dwyer, who is 29 years old and currently living in Minnesota.

Quote from Jan’s older brother Ulf: Jan is a lonely sailor, an innovator and genius. We miss you!

A friend for life

Jan has always been generous with his time, knowledge and resources in helping his colleagues and friends.  Jan was there for me during my darkest hours and thru the many trials and tribulations in life.   i feel fortunate to have an opportunity to work side by side with Jan, it was definitely an opportunity of a lifetime to work with an engineer of his caliber.  

Going out for dim sum at lunch was our favorite thing to do during his retirement years.  Jan was quite adventurous in trying new dim sum dishes although I was unable to get him to eat chicken feet.  We would fight over who gets the check because we can’t seem to remember who paid last time.  Jan looked forward to eating tree riped persimmons from our tree every October and would eat 6 or 7 in one sitting.  He also loved the sugar coated dry fruits every February during Chinese New Year.  Every January, he would bring his laptop over and copy TurboTax and always make an extra copy for me in case I lose the original.  He would do his taxes first and share with me new ways to save on taxes using TurboTax.  I have always been inspired by Jan’s ultra simple life and how little he needed to be content.  

  Jan, I am sorry I was not there for you in your darkest hour and you didn’t get to see Erik one last time, you would have been a proud Dad. 

My memory of Jan

April 16, 2019

I have known Jan for more than a decade. He was one of the most stubborn, particular, detail oriented and unique engineers I have ever known. Once Jan has his mind set, he is very difficult to be persuaded. I remember sitting in the lab next to him and testing inductor modules one by one over and over to get the gain factor. He was so happy that we were making every inductor modules perfect. I also remember him staring at the scope to cut down every extra micro second delay in his test program. He cared about his job greatly. He said that’s his hobby. I will always remember Jan.
