The 3.0SMCJ170A-H is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. Supreme Components International is an authorised distributor of FORMOSA MICROSEMI components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a peak pulse power dissipation of 3000W, a reverse standoff voltage of 170V, and is packaged in an SMC (DO-214AB) package. The 3.0SMCJ170A-H offers fast response time, low clamping voltage, and high surge capability, making it suitable for a wide range of applications, including telecommunications, industrial equipment, and consumer electronics. Its unidirectional configuration provides optimal protection for DC circuits.
