Littelfuse, Inc. has introduced the TPSMA6L series of transient voltage suppression (TVS) diodes. This 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 (P_PPM) rating (600 W) 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.

• 600 W peak pulse power dissipation (P_PPM) rating
• Compliant with IEC 61000-4-2 and IEC 61000-4-4 standards
• AEC-Q101 qualified
• Low profile (less than 1 mm) surface mount package (DO-221AC) and small footprint design
