SZMMSZ3V3T1

Single Zener Diodes Overview

The SZMMSZ3V3T1 is a single Zener voltage regulator diode manufactured by onsemi, designed for surface-mount applications. It features a nominal Zener voltage of 3.3 V with a tight tolerance of 2%. The device operates within a power dissipation rating of 300 mW and maintains a maximum reverse leakage current of 5 uA at the test current of 5 mA. Packaged in an SOD-323-2 form factor measuring 1.7 mm in length, 1.25 mm in width, and 0.9 mm in height, it supports an operating temperature range from -65°C to +150°C. The component exhibits a Zener impedance of 95 Ohms and a forward voltage of 900 mV.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 2% tolerance for stable reference applications
• Designed for high-density board assembly using a compact SOD-323-2 package
• Capable of withstanding extreme thermal environments up to 150°C

Single Zener Diodes Applications

• Voltage reference circuits requiring low profile components
• Protection stages in portable electronic devices
• High-density printed circuit board designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'SZ' indicates automotive qualification requirements, including unique site and control change requests as per onsemi standards. Confirm RoHS compliance status through official datasheets before integration. Ensure the ordering part number matches the exact package and tape/reel specifications required for automated assembly lines.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference with strict 2% accuracy is required in space-constrained layouts. The SOD-323-2 package offers a smaller footprint compared to traditional leaded alternatives. Consider the 300 mW power rating for thermal management in dense assemblies. Verify that the -65°C to +150°C temperature range meets the operational environment constraints of the target application.

Single Zener Diodes Part Context

This device belongs to the MM3Z series of Zener voltage regulators, which are optimized for surface-mount technology. The series provides a convenient alternative to leadless packages while maintaining small body outline dimensions. These diodes are engineered for applications where space is at a premium, such as cellular phones and handheld portables, offering reliable performance in high-density PCB environments.

Single Zener Diodes Replacement Considerations

The MM3Z3V3ST1G shares identical electrical parameters and packaging but may lack the specific automotive prefix requirements. Evaluate if the standard commercial grade suffices or if the SZ prefix's site control changes are mandatory for the production line.
