The STPK30KP220A 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 30000W, the STPK30KP220A offers robust protection against overvoltage events. Its unidirectional configuration ensures optimal performance in DC circuits. With a standoff voltage of 220V, this TVS diode provides a reliable clamping voltage, safeguarding downstream components. The STPK30KP220A is ideal for applications requiring high reliability and superior transient voltage protection, such as power supplies, industrial equipment, and automotive electronics. Its fast response time and low clamping voltage make it an excellent choice for protecting sensitive circuitry.
