SZMMBZ47VALT1G Description

Short technical summary and product information.

The SZMMBZ47VALT1G is a dual monolithic silicon Zener diode array from onsemi, part of the SZMMBZxxxALT1G series designed for transient overvoltage protection. It features a common anode configuration with two Zener diodes in a single SOT-23 package, providing protection for two separate lines while conserving board space.

 

Key electrical specifications include a nominal Zener voltage of 47V with ±5% tolerance, maximum reverse leakage current of 50 nA at 38V, and a peak power rating of 40W at 1.0 ms unidirectional. The device operates over a temperature range of -55°C to 150°C and is rated for 225mW power dissipation on an FR-5 board.

 

The SOT-23-3 (TO-236) package is designed for automated surface mount assembly, making it suitable for high-density applications. The SZ prefix indicates automotive qualification and AEC-Q101 compliance, supporting use in automotive and other applications requiring stringent change control.
