5.0SMDJ170A is a unidirectional transient voltage suppressor (TVS) diode designed for surge and ESD protection in electronic circuits. It features a peak pulse power dissipation of 5000 watts at 1 ms pulse width, a working peak reverse voltage (VRWM) of 170 V, and a breakdown voltage range of 189 V to 209 V. The device offers a maximum clamping voltage of 275 V at peak pulse current of 18.2 A, with typical fast response times less than 1.0 ps. Housed in a compact SMC (DO-214AB) surface mount package, it operates over a temperature range of -55°C to +150°C. This TVS diode is ideal for protecting portable communications, computing, and video equipment from transient voltage events.
