The STPK30KP43CA is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. Supreme Components International is an authorised distributor of SMC Diodes, offering genuine components with full traceability. 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, providing robust protection against high-energy surges. With a standoff voltage of 43V, the STPK30KP43CA effectively clamps overvoltage events, preventing damage to downstream circuitry. Its unidirectional configuration makes it suitable for applications where protection against positive voltage transients is required. Ideal for use in power supplies, telecommunications equipment, and industrial control systems.
