1SMB16AT3G Description

Short technical summary and product information.

The 1SMB16AT3G is a unidirectional transient voltage suppression (TVS) diode manufactured by onsemi. It is designed for general-purpose circuit protection against voltage transients. The device features a reverse standoff voltage (Vwm) of 16V and a clamping voltage of 26V, with a peak pulse current rating of 23.1A. The peak pulse power dissipation is 600W.

 

This TVS diode uses a Zener breakdown mechanism to clamp transient voltages and protect sensitive electronics. It is not designed for power line protection, as the power line protection specification is marked as "No". The device has a typical capacitance of 965pF at 1MHz, which should be considered in high-speed signal applications.

 

The 1SMB16AT3G is housed in a DO-214AA (SMB) surface-mount package and supports an operating temperature range of -65°C to 150°C (junction). This makes it suitable for a wide range of environments. The mounting type is surface mount, compatible with standard SMB footprints.
