The TPK30KP170A is a unidirectional Transient Voltage Suppressor (TVS) Diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components. This TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a high surge capability of 30KW, this device effectively clamps overvoltage events, preventing damage to downstream circuitry. The TPK30KP170A offers a standoff voltage of 170V and is packaged in a DO-203AB package. Its unidirectional configuration ensures optimal protection for DC circuits. This robust TVS diode is ideal for use in power supplies, telecommunications equipment, industrial control systems, and other applications requiring reliable overvoltage protection.
