Low Profile 600W TVS Diode from Littelfuse Protects Sensitive Electronics from Voltage Transients

Low Profile 600W TVS Diode from Littelfuse Protects Sensitive Electronics from Voltage Transients
Littelfuse, Inc has introduced the TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes. This new series 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.
