SZMMBZ4252T1G Description

Short technical summary and product information.

The SZMMBZ4252T1G is a dual monolithic Zener diode designed for transient overvoltage protection. It features a reverse standoff voltage of 22V and a maximum clamping voltage of 40V at peak pulse current. The device is rated for 40W peak pulse power (1ms pulse). It provides two unidirectional channels and one bidirectional channel, making it suitable for protecting two separate lines. The SZMMBZ4252T1G is automotive qualified (AEC-Q101) and is intended for use in voltage and ESD sensitive equipment. It is housed in a surface-mount SOT-23-3 package (TO-236-3, SC-59) and operates over a temperature range of -55°C to 150°C. The device is RoHS3 compliant and has an MSL of 1 (unlimited).
