Need DPAK MOSFET with high avalanche rating

WiscEng · ‎2024-10-07

We've been using the On Semi FDD8453LZ MOSFET (40V, 6.7 ohm, DPAK) in our motor control designs for many years, but this part is now EOL. We're looking for a suitable DPAK replacement. One critical parameter is the single pulse avalanche energy, which must be equal or better than the FDD8453LZ's 253 mJ. Unfortunately this is not a parameter that normally is listed in parametric selection tables. Does ST have a 40V DPAK MOSFET that meets this requirement?

Thanks,

Mark

Welcome @WiscEng, to the community!

what about e.g. the STD120N4F6 with 394mJ in DPAK?
