The TPK15KP43A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. Available at Supreme Components International, an authorised distributor, this device is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a high surge capability of 15kW, the TPK15KP43A offers robust protection in a compact DO-218AB package. Its 43V breakdown voltage (Vbr) ensures reliable clamping action, diverting excess voltage away from protected components. This TVS diode is ideal for use in power supplies, telecommunications equipment, industrial control systems, and other applications requiring high-level transient protection. Supreme Components International is an authorised distributor of electronic components, ensuring quality and reliability.
