MM3Z15VT1G

Single Zener Diodes Overview

The MM3Z15VT1G is a single-channel Zener voltage regulator diode from onsemi, packaged in a surface-mount SOD-323 (SC-76) plastic case. It features a nominal reverse Zener voltage of 15 V with a tolerance range of 14.3 V to 15.8 V at a test current of 5 mA. The device has a steady-state power dissipation rating of 300 mW and a maximum Zener impedance of 30 Ω at the test current. Electrical characteristics include a maximum reverse leakage current of 50 nA at 10.5 V reverse bias and a typical capacitance of 110 pF measured at 1 MHz. The component operates within a junction and storage temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Constructed with void-free, transfer-molded plastic that is corrosion resistant
• SZ prefix variants are AEC-Q101 qualified and PPAP capable for automotive applications

Single Zener Diodes Applications

• Cellular phones
• Hand held portable devices
• High density PC boards

Single Zener Diodes Procurement Notes

Verify the specific suffix 'T1G' indicates tape and reel packaging containing 3,000 units per reel. Confirm whether the 'SZ' prefix variant is required for automotive qualification or standard site control changes. Ensure the ordering part number matches the exact voltage code '0T' for the 15 V specification. Check RoHS compliance status as indicated by the Pb-Free package marking.

Single Zener Diodes Selection Notes

Select this component when a compact SOD-323 footprint is necessary for general-purpose voltage regulation. The 300 mW power rating supports moderate current requirements in low-power circuits. Consider the ±5% tolerance series if precise voltage referencing is not critical. Evaluate the thermal resistance of 416 °C/W for heat dissipation planning on FR-4 boards.

Single Zener Diodes Part Context

This device belongs to the MM3ZxxxT1G series of Zener voltage regulators manufactured by onsemi. The series covers a wide breakdown voltage range from 2.4 V to 75 V in the same small surface-mount package. The MM3Z15VT1G specifically addresses the 15 V segment of this lineup, offering a standardized solution for various consumer electronics and industrial control applications requiring stable reference voltages.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other MM3ZxxxT1G variants with different voltage ratings but identical package and electrical profiles. Cross-brand equivalents must match the SOD-323 outline dimensions, 300 mW power dissipation, and 15 V Zener voltage specifications.
