MMSZ5272BT3G

Single Zener Diodes Overview

The onsemi MMSZ5272BT3G is a single Zener voltage regulator diode housed in an SOD-123 surface-mount package. It provides a nominal reverse Zener voltage of 110 V with a ±5% tolerance, tested at a current of 1.1 mA. The device supports a maximum power dissipation of 500 mW and exhibits a maximum Zener impedance of 750 Ohms at the test current. Reverse leakage current is limited to 100 nA at a reverse voltage of 84 V. The component operates within a junction temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Designed for optimal automated board assembly using a compact SOD-123 plastic case.
• Provides general-purpose voltage regulation suitable for medium current applications.
• Features high electrostatic discharge protection rated at Class 3 per the Human Body Model.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference levels
• High-density printed circuit board designs
• Automated surface-mount assembly processes

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'T3G' corresponds to the required tape and reel shipping quantity of 10,000 units. Confirm that the standard ±5% voltage tolerance meets the design requirements, as tighter tolerances are available in other series variants. Ensure the application environment remains within the specified thermal equilibrium conditions for accurate voltage specification.

Single Zener Diodes Selection Notes

Select this component when a 110 V regulation point is required in a space-constrained surface-mount layout. The SOD-123 package offers a smaller footprint compared to leadless styles while maintaining robust mechanical characteristics. Consider the 500 mW power rating and thermal resistance values to ensure adequate heat dissipation under continuous operating loads.

Single Zener Diodes Part Context

This part belongs to the MMSZ52xxxT1G and SZMMSZ52xxxT1G series of Zener voltage regulators manufactured by onsemi. These devices utilize a void-free, transfer-molded thermosetting plastic case with a corrosion-resistant finish. The series covers a wide Zener voltage range from 2.4 V to 110 V, providing a convenient alternative to traditional leaded packages for modern electronics manufacturing.

Single Zener Diodes Replacement Considerations

The MMSZ5272BT1G serves as a direct functional substitute within the same series, differing primarily in shipping configuration rather than electrical performance. Both parts share identical SOD-123 packaging and electrical specifications.
