Low Profile 600 W TVS Diode

April 9, 2013
Littelfuse, Inc. introduced the TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes.

The TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes from Littelfuse Inc.  can provide secondary transient voltage protection from transients induced by load dump and other transient voltage events for automotive electronic control units, sensors, entertainment systems, and other applications that require high reliability. This SMA device's low profile DO-221AC package is less than 1.1 mm high, but it offers the same peak pulse power dissipation (PPPM) rating (600W) as standard SMB devices. The TPSMA6L Series offers superior electrical performance in a small footprint package, allowing designers to upgrade their circuit protection without altering their existing design footprint or provide more robust protection in new circuit layouts.

The TPSMA6L Series™ low-profile, small-footprint design and 600W rating enable these TVS diodes to provide secondary protection in high reliability, automotive, and portable device applications. They are also AEC-Q101 qualified, which is a critical consideration for automakers because components that meet this specification are suitable for use in the harsh automotive environment without additional component level qualification testing.


·     600W peak pulse power dissipation (PPPM) rating

·     Low profile (less than 1 mm) surface mount package (DO-221AC) and small footprint design

·     Compliant with IEC 61000-4-2 and IEC 61000-4-4 standards
