The 1SMB5917BT3G is a surface mount, uni-directional, 600 watt, transient voltage suppressor (TVS) diode manufactured by ON Semiconductor. It is a low capacitance device that can safely absorb high voltage, high-energy transients. The device is ideal for protecting sensitive components from high-voltage electrostatic discharge (ESD). This device has a breakdown voltage of 24 volts at 5 Amperes, and an ultra-low leakage current of 10 µA. The 1SMB5917BT3G has a maximum operating junction temperature of 175°C, and its RoHS compliant packaging makes it an ideal choice for automotive, metering and other applications.
