The 5KP43A is a Uni-Directional Transient Voltage Suppressor (TVS) Diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components, ensuring you receive genuine and high-quality products. This TVS diode belongs to the 5KP series, known for its robust surge protection capabilities. It's designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). The 5KP43A features a peak pulse power dissipation of 5000W, a reverse standoff voltage of 43V, and a voltage tolerance of 5%. Its uni-directional configuration makes it suitable for applications where protection against positive voltage transients is required. This diode is commonly used in power supplies, telecommunication equipment, and industrial control systems to enhance system reliability and prevent costly damage from voltage surges.
