MM3Z2V4B

Single Zener Diodes Overview

The onsemi MM3Z2V4B is a single Zener diode designed for voltage regulation and protection in surface-mount applications. It features a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%. The device operates within a steady-state power rating of 200 mW and is housed in an SOD-323 (SC-76) package. Key electrical characteristics include a maximum dynamic impedance of 100 Ohms at the test current and a forward voltage of 900 mV at 10 mA. It supports a wide operating temperature range from -65°C to 150°C and meets RoHS compliance standards.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance for sensitive circuit protection.
• Utilizes a compact SOD-323 surface-mount package suitable for space-constrained designs.
• Capable of handling a steady-state power dissipation of 200 mW.

Single Zener Diodes Applications

• Voltage regulation in cellular phones
• Protection circuits in handheld portable devices
• Voltage reference applications on high-density PC boards

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' against the official datasheet to confirm if it denotes a specific tape-and-reel quantity or packaging variant, as standard listings often default to 'T1G'. Ensure the component matches the required ±2% tolerance specification rather than the standard ±5% or ±8% variants found in the general MM3Z series. Confirm RoHS compliance status for the specific manufacturing lot.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference of 2.4 V is required with high precision. The ±2% tolerance makes it suitable for applications where standard Zener tolerances are insufficient. The SOD-323 package offers a balance between thermal performance and board space efficiency compared to larger packages like DO-214AC.

Single Zener Diodes Part Context

The MM3Z2V4B belongs to the MM3ZxxxST1G/SZMM3ZxxxST1G series of Zener Voltage Regulators by onsemi. This series is characterized by its small body outline dimensions and low profile, making it ideal for modern electronics where space is at a premium. The 'B' suffix typically indicates a specific packaging or testing configuration within the broader MM3Z family.

Single Zener Diodes Replacement Considerations

Direct substitutes with identical 2.4 V, 200 mW, and ±2% tolerance specifications should be sought. Generic MM3Z2V4 equivalents with looser tolerances (±5% or ±8%) may not meet precision requirements. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
