SMBJ40A-TR Description

Short technical summary and product information.

The SMBJ40A-TR is a 600W unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.

 

Key electrical specifications include a reverse standoff voltage of 40V, a clamping voltage of 64.5V at a peak pulse current of 9.7A, and a peak pulse power rating of 600W. The device is not intended for power line protection and is rated for general-purpose applications.

 

The SMBJ40A-TR is housed in a surface-mount DO-214AA (SMB) package, with an operating temperature range of -55°C to 150°C. It is suitable for automated assembly and is commonly used in consumer, industrial, and telecommunications equipment requiring transient protection.
