Product Description

The 1SMA5953B is a TVS diode in a compact SMA package, designed as a 600W surge protector for safeguarding sensitive electronics against transient voltage spikes. It features a stand-off voltage of 17.0V, a breakdown voltage of 20.2V, and a maximum reverse leakage current of 5µA. With a peak pulse current of 23.8A and a clamping voltage of 28.5V, it efficiently suppresses high-energy transients. Operating across a temperature range of -55°C to +150°C, this diode is ideal for applications in power supplies, communication systems, automotive electronics, and industrial equipment. Key advantages include its high surge capacity, fast response time, and rugged SMA package for reliable PCB mounting. However, its limited power handling compared to larger TVS devices may require additional protection in extreme conditions.
