This value can be built by a 0.68

MOSFET (Q1) and Diode (D1)

The MOSFET and diode must be dimensioned with a minimum 50% safety rating of their relevant voltage and

current parameters. Thus a FET with minimum 500V drain-source breakdown voltage and 0.6A drain current as

well as a fast recovery diode with at least 500V reverse voltage and a 0.6A forward current may be selected.

ESD/Latch-Up-Protection

All pins have an ESD protection of >± 2000V according human body model (HBM). The ESD test follows the

H

uman Body Model with 1.5 kΩ/100 pF based on MIL 883-G, Method 3015.7

Latch-up protection of >± 100mA has been proven based on JEDEC No. 78A Feb. 2006, temperature class 1.
