Note 2. Pulse test: Pulse Width = 300µs, Duty Cycle ≤ 2%.
Note 3. The internal Collector–Emitter diode can eliminate the need for an external diode to clamp
inductive loads. Tests have shown that the Forward Recovery Voltage (V
) of this diode is
F
comparable to that of typical fast recovery rectifiers.
