MM5Z3V6ST1G

Single Zener Diodes Overview

The MM5Z3V6ST1G is a single Zener voltage regulator diode from the MM5ZxxxST1G series, manufactured by onsemi. It is housed in a SOD-523 surface-mount package with dimensions of 1.20 mm x 0.80 mm and a low body height of 0.7 mm. The device provides a nominal Zener voltage (VZ) of 3.6 V with a tight tolerance range of 3.60 V to 3.85 V at a test current (IZT) of 5.0 mA. It features a steady-state power rating of 500 mW, a maximum reverse leakage current of 1.0 µA at 5.0 V, and a maximum Zener impedance (ZZK) of 90 Ω at 1.0 mA. The component operates within a junction temperature range of -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation protection in a compact SOD-523 surface mount package designed for space-constrained applications.
• Features tight tolerance specifications for stable Zener breakdown voltage performance across operating conditions.
• Offers high electrostatic discharge (ESD) immunity rated at Class 3 (> 16 kV) per the Human Body Model.

Single Zener Diodes Applications

• Cellular phones
• Handheld portable devices
• High density PC boards

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches ST1G for standard tape and reel packaging containing 3,000 units per reel. Confirm RoHS compliance and lead-free status as specified in the datasheet. Ensure the application environment remains within the stated thermal limits to maintain reliability. Check for specific marking codes corresponding to the 3.6 V variant during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference or clamp is required in a minimal footprint design. The tight tolerance makes it suitable for precision circuits where standard Zener variations are unacceptable. Consider the 500 mW power dissipation capability relative to the board's thermal characteristics. Verify that the SOD-523 package aligns with the PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the MM5ZxxxST1G series of Zener Voltage Regulators, which covers a standard breakdown voltage range from 2.4 V to 18 V. The series is characterized by its small body outline dimensions and suitability for automated board assembly. It serves as a general-purpose voltage regulation solution for consumer electronics and industrial applications requiring reliable surface-mount components.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include MM5Z3V3ST1G (3.3 V) and MM5Z3V9ST1G (3.9 V). Automotive-grade equivalents with unique site control requirements are available under the SZMM5Z prefix, such as SZMM5Z3V6ST1G, which are AEC-Q101 qualified and PPAP capable.
