P6SMB18A Description

Short technical summary and product information.

The P6SMB18A is a 600W peak pulse power transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It is unidirectional with a single channel and features a reverse stand-off voltage of 15.3V and a maximum clamping voltage of 25.5V. The device can handle peak pulse currents up to 24.2A under a 10/1000μs waveform.

 

This TVS diode offers excellent clamping capability and fast response time of less than 1.0 ps. It has a typical leakage current of less than 1 μA and is suitable for general purpose protection applications including I/O interfaces, VCC bus, telecom, computer, industrial, and consumer electronics.

 

The P6SMB18A is housed in a surface mount DO-214AA (SMB) package, which is optimized for minimal PCB space impact. It supports an operating junction temperature range of -55°C to 150°C and is compliant with MSL level 1. The device is halogen free and RoHS compliant.
