SMBJ51A Description

Short technical summary and product information.

The SMBJ51A from Littelfuse Inc. is a unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients. It is part of the SMBJ series and offers a peak pulse power rating of 600W for 10/1000μs waveforms.

 

The device features a clamping voltage of 82.4V and a peak pulse current of 7.3A. It utilizes Zener technology and provides a fast response time of less than 1 ps. The operating temperature range spans from -65°C to 150°C, making it suitable for harsh environments.

 

The SMBJ51A is offered in a surface-mount DO-214AA (SMB) package, also referred to as SMBJ. It is RoHS compliant, halogen free, and rated MSL level 1 for unlimited floor life. The package is designed for optimal board space utilization and provides built-in strain relief.

 

Ideal for general purpose transient protection in telecom, computer, industrial, and consumer electronics, the SMBJ51A is commonly used on I/O interfaces, VCC buses, and other vulnerable circuits. It is not intended for power line protection.
