This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

BOURNS SM8S-Q Transient Voltage Suppressor Diode

Bourns SM8S-Q Transient Voltage Suppressor Diodes offer high peak power dissipation and a fast response in a compact package, ideal for protecting power supplies and data lines in automotive and other harsh applications. 

The SM8S-Q are housed in a compact DO-218 chip package to minimize board space and can dissipate up to 6600W. They offer a very fast response time, typically less than 1.0 picosecond, providing robust protection against voltage transients and ESD events. 

The TVS diodes are offered in unidirectional and bidirectional variants and with working peak reverse voltages from 16V to 43V. The SM8S-Q TVS diodes are AEC-Q101 compliant for use in automotive applications and they’re rated for operation from -55°C to +175°C, enabling their use in high temperature applications.
