P6SMB33A Description

Short technical summary and product information.

The Littelfuse P6SMB33A is a 600W unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. Key specifications include a reverse standoff voltage of 28.2V, a maximum clamping voltage of 45.7V at 13.3A peak pulse current (10/1000μs waveform), and a peak pulse power rating of 600W.

 

This device offers fast response time typically less than 1.0ps and provides ESD protection up to 30kV air discharge and 30kV contact discharge per IEC 61000-4-2. It is suitable for general purpose applications such as I/O interfaces, VCC bus, telecom, computer, industrial, and consumer electronics. The operating temperature range is -55°C to 150°C (junction).

 

The P6SMB33A is packaged in a DO-214AA (SMB) surface mount package, optimized for minimal PCB space. It is RoHS compliant, halogen free, and Pb-free E3 with matte tin lead-free plating. The device meets MSL level 1 per J-STD-020 and is UL recognized to ANSI/UL 497B.
