ELECTRICAL CHARACTERISTICS (CONTINUED)

Table 7: Dynamic

Table 8: Source Drain Diode

(1) Pulsed: Pulse duration = 300 µs, duty cycle 1.5 %.

(2) Pulse width limited by safe operating area.

(3) Coss eq. is defined as a constant equivalent capacitance giving the same charging time as Coss when VDS increases from 0 to 80% VDSS.
