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.
