Product Description

The 1SMA5942B TVS Diode is a high-performance transient voltage suppressor designed for robust surge protection in demanding environments. As a High Power TVS Diode, it handles peak pulse power up to 1500W (10/1000μs waveform) with a standoff voltage of 59V and breakdown voltage of 65.7V. This unidirectional 1SMA5942B Transient Suppressor operates within a -55°C to +175°C temperature range, featuring an SMA/DO-214AC package for compact integration. It supports DC voltage systems up to 42V, making it ideal for automotive electronics, industrial controls, and telecom infrastructure. Key advantages include ultra-fast response (<1ps), low leakage current, and excellent clamping capability. While optimized for overvoltage protection, proper thermal management is required for sustained high-energy transients. Its single-port configuration protects sensitive components from ESD, lightning strikes, and inductive load switching surges.
