Notes 1. PW ≤ 10 µs, Duty Cycle ≤ 1 %
2. Mounted on FR-4 Board, t ≤ 5 sec.
Remark The diode connected between the gate and source of the transistor serves as a protector against ESD. When
this device actually used, an additional protection circuit is externally required if a voltage exceeding the rated
voltage may be applied to this device.
