Product Overview
The SM05 is a unidirectional ESD protection device designed to protect sensitive signal and interface lines from electrostatic discharge, electrical fast transients, and surge events. It features a 5V reverse standoff voltage, a 6.2V to 7.3V breakdown voltage range, and a maximum clamping voltage of 9.8V. With 300W peak pulse power capability and 12A peak pulse current, it provides robust transient suppression for low-voltage electronic circuits.
Packaged in a compact SOT-23 surface-mount package, the SM05 is suitable for communication interfaces, control lines, portable electronics, and other low-voltage circuits requiring ESD and surge protection.
