The 1SMB54A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by CENTRAL SEMICONDUCTOR. Supreme Components International is an authorized distributor of CENTRAL SEMICONDUCTOR components. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), inductive load switching, and other transient voltage events. The 1SMB54A features a standoff voltage of 54V and is packaged in a compact DO-214AA (SMB) surface-mount package. It offers fast response time, high surge capability, and excellent clamping characteristics. This diode is ideal for use in a wide range of applications, including telecommunications, industrial equipment, and consumer electronics, where reliable transient voltage protection is required.
