Product Introduction

The SMAJ13A is a unidirectional surface-mount transient voltage suppressor (TVS) designed for overvoltage and surge protection of 13 V DC circuits. It adopts SMA (DO-214AC) package with 400 W peak pulse power capability for 10/1000 μs surge waveform.

Core Advantages

  • High peak-pulse surge handling;
  • Excellent clamping performance;
  • Ultra-fast response speed;
  • Low reverse leakage current;
  • Low-inductance SMA (DO-214AC) surface-mount package;

Key Features

High peak-pulse surge handling400 W peak pulse power
under 10/1000 μs surge waveform, peak pulse current IPP up
to 18.6 A, offers robust transient-surge suppression capability;
Excellent clamping performanceMax clamping voltage VC = 21.5 V at IPP; VBR(min)=14.4 V, ensures no false avalanche triggering for 13 V nominal working circuits;
Ultra-fast response speedTypical response time less than 1.0 ps from 0 V to minimum breakdown voltage, rapidly clamps EFT and ESD transients;
Low reverse leakage currentIR ≤1 μA at rated stand-off voltage VRWM=13 V, brings tiny static power consumption, suitable for low-power circuits.

  • Replacement:
  • DIODES: SMAJ13A;
  • Nexperia: SMAJ13A;
  • AOS: SMAJ13A;
  • ST: SMAJ13A;
  • Replacement Rationale: Pin-to-pin & parameter compatible; cost saving with no PCB modification.
