The 1SMB5930BT3G is a surface-mount, silicon, unidirectional transient voltage suppressor manufactured by ON Semiconductor. This device is designed to protect sensitive electronic components from voltage spikes, static charge, and other power disturbances. It features a working peak power dissipation of 500 watts, while the maximum clamping voltage at 8A is 26.5V. It operates on voltages from 5.8 to 48V, and has a response time of 11ns typical. Its low leakage current of 10nA at 24V ensures minimal power is lost when the device is in protection mode. The 1SMB5930BT3G is ideal for applications such as TVS protection in LCD/LED computer/TV displays, port protection in portable electronic devices, and protection against surge currents when used in AC/DC power supplies.
