Product overview

Description

The SMBJ series is designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2 and MIL STD 883, method 3015, and electrical overstress according to IEC 61000-4-4 and 5, induced by inductive load switching, lighting and other transient voltage events on ICs, MOSFETs, signal lines. This device is more generally used against surges below 600 W (10/1000 μs).

The Planar technology makes it suitable for high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time.

The SMBJ series is packaged in SMB.

All features
Peak pulse power: 600 W (10/1000 μs) and 4 kW (8/20 μs)

Typical failure mode is short from over-specified voltage or current

Stand-off voltage range from 5 V to 188 V

Unidirectional and bidirectional types

Low leakage current: 0.2 μA at 25 °C and 1 μA at 85 °C

Operating T_j max: 150 °C

High power capability at T_j max.: up to 350 W (10/1000 µs)

Excellent clamping capability

Very fast response time

Lead finishing: matte tin plating
