The SMCJ78A is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. This surface-mount device is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a peak pulse power dissipation of 600W, the SMCJ78A effectively clamps transient voltages to a safe level, preventing damage to downstream circuitry. Its 78V standoff voltage makes it suitable for a wide range of applications. Supreme Components International is an authorised distributor of SMC DIODES, ensuring that you receive only genuine, high-quality components. The SMCJ78A's compact SMC package allows for efficient board space utilization. This TVS diode is ideal for use in telecommunications equipment, industrial controls, and consumer electronics.
