The STPK30KP300A 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 standoff voltage of 300V and a high peak pulse power dissipation of 30000W, the STPK30KP300A effectively clamps overvoltage events, preventing damage to downstream components. It is housed in a P600 package, offering robust performance and ease of installation. Ideal for applications requiring high surge protection, this TVS diode enhances the reliability and longevity of electronic systems. Its unidirectional configuration provides optimal protection for DC circuits.
