1SMB48AT3G Description

Short technical summary and product information.

The 1SMB48AT3G is a 600W peak pulse power TVS diode designed for transient voltage protection. It features a reverse standoff voltage of 48V, a minimum breakdown voltage of 53.3V, and a maximum clamping voltage of 77.4V at 7.7A peak pulse current. This unidirectional device has a single channel and a capacitance of 365pF at 1 MHz.

 

Operating over a temperature range of -65°C to 150°C, it is housed in a surface mount DO-214AA (SMB) package. Based on the 1SMB5.0AT3G series datasheet, it is suitable for general purpose applications including communication systems, automotive, industrial, and power supplies. It offers fast response time (<1 ns) and low leakage current.

 

Note: The part is listed as RoHS3 compliant, REACH unaffected, and MSL 1, but these compliance statuses are unverified. No distributor pricing is available in this data set.
