IRF820AS, SiHF820AS, IRF820AL, SiHF820AL
Vishay Siliconix
Note
a. When mounted on 1" square PCB (FR-4 or G-10 material).
Notes
a. Repetitive rating; pulse width limited by maximum junction temperature (see fig. 11).
b. Pulse width 300 μs; duty cycle 2 %.
c. Coss eff. is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 % to 80 % VDS.
d. Uses IRF820A/SiHF820A data and test conditions.
