FAQ

What is the maximum short-circuit withstand time for the AOTF20B65M2?

The device can withstand a short circuit for up to 5 microseconds, provided the junction temperature remains below 150°C and the collector-emitter voltage is within limits.

How does the junction temperature affect the collector-emitter saturation voltage?

The VCE(sat) increases with temperature; it is specified at 1.7V at 25°C and rises to 2.15V at 150°C under rated current conditions.

What are the typical switching energies at 25°C?

At 25°C, the turn-on energy (Eon) is typically 0.58mJ and the turn-off energy (Eoff) is typically 0.28mJ, resulting in a total switching energy of 0.86mJ.
