Product Introduction

The SMAJ58A is a unidirectional 400 W TVS diode in SMA (DO-214AC) package for 58 V DC surge protection. It delivers fast response, low reverse leakage and reliable clamping performance against ESD and surge transients. Halogen-free, tape-and-reel packaged for high-volume SMT assembly, operating from-55 ℃ to +150 ℃. Suitable for industrial power rails and telecom systems.

Core Advantages

  • 400 W peak-pulse surge capacity;
  • Excellent clamping capability;
  • Low profile package and low inductance;
  • Ultra-fast response;
  • Ultra-low reverse leakage;
  • Low-inductance SMA (DO-214AC) surface-mount package;

Key Features

400 W peak-pulse surge capacityDelivers 400 W peak pulse power
under 10/1000 μs surge waveform, with IPP up to 4.3 A for robust over
-voltage protection for 58 V DC circuits;
Reliable clamping performanceStand-off voltage VRWM=58 V, minimum breakdown voltage VBR(min)=64.4 V, maximum clamping voltage VC=93.6 V, avoids false avalanche triggering under normal operating conditions;
Ultra-fast responseTypical response time less than 1.0 ps, quickly suppresses ESD and electrical fast transient spikes;
Ultra-low reverse leakageIR ≤1 μA at rated VRWM, minimal static power consumption for high-impedance circuits.
