SZMM5Z9V1T1G

Single Zener Diodes Overview

The SZMM5Z9V1T1G is a single Zener voltage regulator diode manufactured by onsemi, designed for transient overvoltage protection in space-constrained applications. It features a nominal Zener voltage of 9.1 V with a tight tolerance of ±2% and a steady-state power dissipation rating of 500 mW. The device operates within a temperature range of -65°C to +150°C and exhibits a maximum reverse leakage current of 500 nA at 6 V. Packaged in the compact SOD-523 (SC-79) surface-mount footprint measuring 1.2 mm x 0.8 mm x 0.6 mm, it offers low body height and high ESD protection capability exceeding 16 kV per IEC standards.

Single Zener Diodes Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as ST1G or T1G may indicate different packaging formats like cut tape versus reel. Confirm RoHS compliance status and AEC qualification requirements specific to automotive or industrial deployment scenarios before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference is required in ultra-compact form factors. Ensure the application environment stays within the specified -65°C to +150°C operating range. Consider the 500 mW power rating for thermal management in dense layouts where airflow is limited.

Single Zener Diodes Part Context

This device belongs to the MM5Z series of silicon Zener diodes produced by onsemi. The series is characterized by its small outline dimensions and suitability for modern surface-mount technology assembly processes. It serves as a fundamental discrete semiconductor component for voltage regulation and protection tasks across consumer and industrial electronics sectors.

Single Zener Diodes Replacement Considerations

Cross-reference with other MM5Z series variants for different voltage ratings. Verify pinout compatibility and thermal characteristics when substituting with equivalent SOD-523 Zener diodes from other manufacturers to ensure functional parity.
