The SMBJ43A is a unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients. Manufactured by SMC DIODES, this diode features a standoff voltage of 43V and a peak pulse power dissipation of 600W. Its fast response time and low clamping voltage make it an excellent choice for safeguarding circuits against ESD, EFT, and lightning strikes. The SMBJ43A is commonly used in telecommunications, industrial control, and consumer electronics applications. Supreme Components International is an authorised distributor of SMC DIODES, ensuring you receive genuine, high-quality components. This TVS diode offers reliable overvoltage protection in a compact SMB package.
