Copper, in a still air environment with T A=25°C. The value in any given application depends on the user's specific board design. B: Repetitive rating, pulse width limited by junction temperature. C. The R θJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient. D. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25°C. The SOA curve provides a single pulse rating. F. The current rating is based on the t≤ 10s junction to ambient thermal resistance rating.

I've placed many orders from Heisener . I have never had an error with any order, the order has always went out the same day, and the items are always well packaged.


November 19, 2020

They worked great. Not much to say - as far as I can tell they adhere to the specs, and did the job I needed them to. Good transistors for higher current situations.


November 19, 2020

Used it on my system it works perfect as I need.


November 17, 2020

Very happy for the fast shipping and good price!


November 17, 2020

Quality electronic components plus fast response.Thank you.
