ESDLIN1524BJ

TRANSIL™ diode for ESD protection

Features

■ Max peak pulse power 160 W (8/20 µs)

■ Asymmetrical bidirectional device

■ Stand-off voltage: 15 and 24 V

■ Low clamping factor V

■

Complies with the following standards :

– IEC 61000-4-2 level 4 (> 15 kV air

discharge, > 8 kV contact discharge)

– IEC 61000-4-5; I

= 3 A (8/20 µs)

– HBM MIL STD 833, class 3 (> 4 kV)

■ Low Leakage current

Description

The ESDLIN1524BJ is an asymmetrical

TRANSIL diode designed specifically for

protecting one automotive LIN bus line against

electrostatic discharge (ESD). The SOD-323 is a

very small package which allows space saving on

high density printed circuit board .

Transil diodes provide high overvoltage protection

by clamping action and have instantaneous

response to transient overvoltages.
