MSMLG5.0A – MSMLG170CAe3, MSMLJ5.0A – MSMLJ170CAe3 Surface
Mount 3000 Watt Transient Voltage Suppressor
1
Product Overview
The MSMLG5.0A–MSMLG170CA and the MSMLJ5.0A–MSMLJ170CA series of high-reliability transient
voltage suppressors (TVS) protect circuits from voltage spikes containing up to 3000 W (10/1000 μs
model pulse). The SMLG gull-wing design in the DO-215AB package allows for visible solder connections.
The SMLJ J-bend design in the DO-214AB package allows for greater PC board mounting density.
Selections include unidirectional and bidirectional as well as RoHS-compliant versions. These are
available with a variety of upscreening options for enhanced reliability. They protect against the
secondary effects of lightning per IEC61000-4-5 and against voltage pulses from inductive switching
environments and induced by RF radiation. Since their response time is virtually instantaneous, they can
also be used in protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
