The STPK30KP45A 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). It features a high peak pulse power dissipation of 30000W, ensuring robust protection in demanding applications. The STPK30KP45A has a standoff voltage of 45V and is available in a DO-214AB package, making it easy to integrate into existing circuit designs. This device is ideal for use in power supplies, telecommunications equipment, industrial control systems, and other applications where transient voltage protection is critical. Its unidirectional configuration provides optimal protection for DC circuits.
