SM6T

Transil™

Features

■ Peak Pulse Power: 600 W (10/1000 µs)

■ Breakdown voltage range:

From 6.8 V to 220 V

■ Uni and Bidirectional types

■ Low clamping factor

■ Fast response time

■ UL recognized

Description

The SM6T Transil series has been designed to

protect sensitive equipment against electrostatic

discharges according to IEC 61000-4-2, MIL STD

883E Method 3015, and electrical over stress

such as IEC 61000-4-4 and 5. They are, more

generally, suitable for surges below 600 W,

10/1000 µs

This planar technology makes the SM6T

compatible with high-end equipment and SMPS

where low leakage current and high junction

temperature are required to provide reliability and

stability over time.

Automotive grade versions are available (see

Section 4: Ordering information).
