SMBJ350A Description

Short technical summary and product information.

The SMBJ350A is a 600W unidirectional transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It is housed in a compact DO-214AA (SMB) surface mount package, suitable for automated assembly and space-constrained designs.

 

Key electrical specifications include a reverse standoff voltage of 350V, a clamping voltage of 567V at a peak pulse current of 1.1A (10/1000μs waveform), and a fast response time of less than 1.0ps. The device is rated for a peak pulse power dissipation of 600W and operates over a junction temperature range of -65°C to 150°C.

 

The SMBJ350A is RoHS compliant, halogen free, and meets MSL level 1 per J-STD-020. It is intended for general purpose applications such as protecting I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
