Product overview

Description

The SM15T TVS series is designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2, MIL STD 883 Method 3015, and electrical overstress such as IEC 61000-4-4 and 5. They are used for surges below 1500 W 10/1000 μs.

This planar technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time.

All features
Peak pulse power:

1500 W (10/1000 μs)

up to 10 kW (8/20 μs)

Stand-off voltage range from 5 V to 188 V

Unidirectional and bidirectional types

Low leakage current: 0.2 µA at 25 °C

Operating T_j max: 150 °C

High power capability at T_j max.: up to 1250 W (10/1000 µs)

Lead finishing: matte tin plating
