Series: TPSMA6L Questions? Contact Littelfuse Support
Littelfuse TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes can provide secondary transient voltage protection from transients induced by load dump and other transient voltage events for sensitive electronics. 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.

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


  • Automotive electronic control units, sensors, entertainment systems
  • Portable devices that require high reliability
