ELECTRICAL CHARACTERISTICS (CONTINUED)

SWITCHING ON (RESISTIVE LOAD)

SWITCHING OFF (INDUCTIVE LOAD)

SOURCE DRAIN DIODE

GATE-SOURCE ZENER DIODE

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

2. Pulse width limited by safe operating area.

PROTECTION FEATURES OF GATE-TO-SOURCE ZENER DIODES

The built-in back-to-back Zener diodes have specifically been designed to enhance not only the device’s

ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be

applied from gate to souce. In this respect the 25V Zener voltage is appropiate to achieve an efficient and

cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid the

usage of external components.
