The STPK30KP120A, manufactured by SMC DIODES, is a robust unidirectional Transient Voltage Suppressor (TVS) diode. Supreme Components International is an authorised distributor of SMC DIODES components. This TVS diode is engineered to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a high peak pulse power dissipation of 30000W, the STPK30KP120A offers superior protection against high-energy surges. Its 120V standoff voltage makes it suitable for a wide range of applications. The unidirectional configuration ensures optimal performance in DC circuits. With its fast response time and excellent clamping capability, this TVS diode provides reliable and effective protection for critical electronic systems. Ideal for use in power supplies, industrial control systems, automotive electronics, and telecommunications equipment.
