onsemi 1SMB5938BT3

The Onsemi 1SMB5938BT3 is a surface mount, 3W TVS (Transient Voltage Suppression) diode that offers reliable protection against transient voltage spikes in various electronic circuits. It features a uni-directional design that allows for quick clamping of high transient voltages and a maximum breakdown voltage of 58.1V. The diode has a low leakage current of 1µA, which ensures optimal energy dissipation during transient voltage protection. The SMB package of the diode allows for easy pick and place operations during surface mount assembly and provides a physical footprint suitable for space-constrained configurations.

The diode is designed to comply with various international standards such as RoHS and is frequently used in communication equipment, automotive systems, industrial equipment, and consumer electronics applications. The diode works by diverting unwanted transient voltages away from sensitive electronic components and circuits, which in turn prevents damages such as short-circuits and component failure. Its high surge capability of up to 100A enables it to provide long-lasting protection to electronic devices
