MM5Z24VT1G

Single Zener Diodes Overview

The MM5Z24VT1G is a single-channel Zener voltage regulator diode from onsemi, packaged in a surface-mount SOD-523 (CASE 502) outline. It provides a nominal reverse Zener voltage of 24 V with a standard tolerance range of 22.8 V to 25.6 V at a test current of 5 mA. The device features a steady-state power dissipation rating of 500 mW and a maximum Zener impedance of 70 Ω at the test current. Electrical characteristics include a maximum reverse leakage current of 50 nA at 22 V and a typical voltage temperature coefficient of 16.8 mV/K. The component operates within a junction and storage temperature range of -65 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and tape-and-reel specifications. Ensure that the required AEC-Q101 qualification and PPAP capability are explicitly requested if the application involves automotive or stringent control change requirements. Confirm RoHS compliance and lead finish details prior to final procurement decisions.

Single Zener Diodes Selection Notes

Select this component when space-constrained designs require a reliable voltage reference with a nominal breakdown near 24 V. The SOD-523 package is suitable for automated surface mount assembly processes. Evaluate the thermal derating curve to ensure the 500 mW power rating remains sufficient under expected operating ambient temperatures above 25 °C.

Single Zener Diodes Part Context

This device belongs to the MM5ZxxxT1G series of Zener Voltage Regulators manufactured by onsemi. The series covers a wide standard Zener breakdown voltage range from 2.4 V to 75 V. All devices in this family share the same SOD-523 surface mount package and are designed to offer consistent performance characteristics for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent SOD-523 Zener diodes with a 24 V nominal voltage and 500 mW power rating. Verify that any substitute part matches the electrical parameters, specifically the Zener impedance and leakage current limits, as well as the physical footprint dimensions.

Single Zener Diodes FAQ

What is the maximum Zener impedance specified for the MM5Z24VT1G?

The maximum Zener impedance (ZZT) is specified as 70 Ω at the test current (IZT) of 5 mA.

Does the MM5Z24VT1G support automotive applications requiring unique site control?

Standard MM5Z24VT1G parts do not inherently carry the SZ prefix. The SZMM5Z24VT1G variant is designated for automotive and other applications requiring unique site and control change requirements, and is AEC-Q101 qualified.
