The SMBJ54A-A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by SMC DIODES. Supreme Components International is an authorised distributor of SMC DIODES components. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a standoff voltage of 54V and a peak pulse power dissipation of 600W, the SMBJ54A-A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its unidirectional configuration ensures optimal protection for DC circuits. Housed in a compact SMB package, this diode offers excellent surge handling capability and fast response time. Ideal for use in power supplies, communication equipment, and industrial control systems, the SMBJ54A-A enhances the reliability and durability of electronic devices.
