Littelfuse SZSMF4L AEC-Q101 TVS Diodes

Littelfuse SZSMF4L AEC-Q101 TVS Diodes offer a peak power rating of 400W and a response time that is typically <1ns. These TVS diodes are designed to protect sensitive systems or components from high-voltage, high-energy transients. SZSMF4L diodes feature low Zener impedance, high surge, and excellent clamping capabilities. Littelfuse SZSMF4L AEC-Q101 TVS Diodes have a small size, making them ideal for use in automotive electronic applications.
