Single FETs, MOSFETs FAQ

Is the AUIRLR3110Z suitable for repetitive avalanche operation?

Yes, the datasheet explicitly states that repetitive avalanche is allowed up to the maximum junction temperature, with specific energy ratings provided for single pulse and repetitive conditions.

What is the difference between the silicon-limited and package-limited drain current?

The silicon-limited current (63A) represents the theoretical maximum based on the die's thermal capacity, while the package-limited current (42A) accounts for the physical constraints of the D-Pak package leads and bond wires.
