MM3Z2V7ST1

Single Zener Diodes Overview

The MM3Z2V7ST1 is a Zener voltage regulator diode from onsemi, packaged in a SOD-323 surface-mount case. It provides a nominal Zener voltage range of 2.67 V to 2.91 V at a test current of 5 mA. The device features a steady-state power dissipation rating of 200 mW and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 1000 Ω at the test current and a reverse leakage current of 1.0 µA at a reverse voltage of 0.5 V. The package dimensions are 1.7 mm by 1.25 mm with a body height of 0.9 mm.

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS requirements if lead-free packaging is required. Confirm that the operating conditions remain within the specified thermal resistance and power derating limits to maintain device reliability.

Single Zener Diodes Selection Notes

Select this component when a low-profile surface-mount Zener diode is needed for tight voltage regulation applications. Consider the 200 mW power dissipation limit and the specific Zener impedance values for the target circuit design. Verify that the SOD-323 package dimensions fit the available PCB real estate constraints.

Single Zener Diodes Part Context

This component belongs to the MM3ZxxxST1 series of Zener voltage regulators manufactured by onsemi. The series utilizes a SOD-323 surface-mount plastic package designed for general-purpose voltage regulation. The product line emphasizes small body outline dimensions and low profile to support high-density electronic board layouts.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include MM3Z2V4ST1G and MM3Z3V3ST1G. Verify that alternative part numbers match the required Zener voltage range and power dissipation ratings before implementation.
