MM3Z47VT1G

Single Zener Diodes Overview

The MM3Z47VT1G is a single Zener diode voltage regulator from the MM3ZxxxT1G series, manufactured by onsemi. It provides a nominal Zener voltage of 47 V with a tolerance range of 44 V to 50 V at a test current of 2 mA. The device features a maximum Zener impedance of 170 Ohms and a reverse leakage current of 50 nA at 32.9 V. It operates within a junction temperature range of -65 °C to +150 °C and has a steady-state power dissipation rating of 500 mW (derated above 25 °C). The component is housed in a SOD-323 surface mount package.

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required electrical characteristics, particularly the 47 V nominal voltage and 500 mW power rating. Confirm the package type is SOD-323 and check for the SZ prefix if automotive qualification or unique site control is required. Ensure compliance with RoHS directives and Pb-Free manufacturing standards before procurement.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount solution is needed for voltage clamping or regulation. The SOD-323 package offers small body dimensions suitable for dense layouts. Consider the thermal derating requirements above 25 °C and ensure the application environment stays within the specified operating temperature range of -65 °C to +150 °C.

Single Zener Diodes Part Context

This device belongs to the MM3ZxxxT1G series of Zener voltage regulators. The series covers a standard breakdown voltage range from 2.4 V to 75 V. All devices in this family share the same SOD-323 surface mount package and are designed to provide reliable voltage regulation in applications where physical space is limited.

Single Zener Diodes Replacement Considerations

The SZMM3Z47VT1G is an equivalent part within the same series, offering identical electrical specifications but qualified under AEC-Q101 standards for automotive applications requiring unique site and control change requirements.
