SMBG5923A/TR13

Single Zener Diodes Overview

The SMBG5923A/TR13 is a single Zener diode manufactured by Microsemi Corporation, designed for surface-mount applications in the DO-214AA (SMBG) package. It features a nominal Zener voltage of 8.2 V with a tolerance of ±10% and a maximum power dissipation of 2 W. Key electrical specifications include a maximum impedance of 3.5 Ohms and a reverse leakage current of 5 µA at 6.5 V. The device operates within a temperature range of -65°C to 150°C and has a forward voltage of 1.2 V at 200 mA. This component is classified as non-RoHS compliant and was subject to an End-of-Life notification in April 2016.
