Product Description

The 1SMA5945B TVS Diode is a high-performance surge suppressor designed to protect sensitive electronics from transient voltage spikes up to 58V. This unidirectional device features a peak pulse current handling capability of 53.3A (typical) and operates within a working voltage range of 58V, with a breakdown voltage of 64.4-71.2V. It offers robust clamping performance for overvoltage protection in circuits exposed to lightning surges, ESD events, or inductive load switching. Ideal for automotive, industrial control, and power supply systems, this SMAJ5945B-compatible diode supports -55°C to +150°C operation and utilizes a compact SMA package for space-constrained designs. Its rapid response time (<1ps) and low leakage current ensure reliable protection, though repeated high-energy transients may gradually degrade performance.
