1SMB51AT3 Description

Short technical summary and product information.

The 1SMB51AT3 is a 600W peak power unidirectional transient voltage suppressor (TVS) diode from On Semiconductor. It is designed for general purpose applications to protect sensitive electronic components from high voltage transients. The device provides a maximum clamping voltage of 82.4V and can handle a peak pulse current of 7.3A.

 

This TVS diode offers a typical capacitance of 345pF at 1MHz and operates over a wide temperature range of -65°C to 150°C. It is a single-channel unidirectional device, meaning it protects one line with a defined polarity.

 

The 1SMB51AT3 is supplied in a surface mount DO-214AA (SMB) package, which features a modified L-bend lead style for improved solderability. The package is void-free, transfer-molded thermosetting plastic, and the cathode is indicated by a polarity band. The device is suitable for automated assembly and is rated for lead-free soldering at 260°C for 10 seconds.
