SA33ARL

The SA33ARL is a unidirectional Zener Transient Voltage Suppressor (TVS) diode from ON Semiconductor, part of the SA5.0A series. Designed to protect voltage-sensitive components from high-energy transients, it features excellent clamping capability, high surge capability, and fast response times.

Key electrical specifications include a 500W peak power dissipation at 1.0 ms, a working peak reverse voltage range of 5.0V to 170V, and a breakdown voltage of 33V. The clamping voltage is 53.3V at a peak pulse current of 9.4A. It also offers a low leakage current of less than 1 uA above 8.5V and an ESD rating of Class 3 (>16 kV) per the Human Body Model.

This device is supplied in ON Semiconductor's Surmetic axial leaded package (DO-204AC, DO-15) and is suitable for through-hole mounting. Its mechanical characteristics include a void-free, transfer-molded, thermosetting plastic case with corrosion-resistant external surfaces and readily solderable leads. The operating temperature range is -55°C to 175°C.

The SA33ARL is ideally suited for use in communication systems, numerical controls, process controls, medical equipment, business machines, power supplies, and many other industrial and consumer applications requiring robust transient voltage protection.
