Notes 1. PW ≤ 10 µs, Duty Cycle ≤ 1 %
2. Mounted on ceramic substrate of 5000 mm2 x 1.1 mm
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.
