MMSZ5261BT1G

Single Zener Diodes Overview

The MMSZ5261BT1G is a single-channel Zener voltage regulator diode manufactured by onsemi, housed in an SOD-123 surface-mount package. It features a nominal Zener voltage of 47 V with a ±5% tolerance and a maximum power dissipation of 500 mW. The device operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a test current (IZT) of 2.7 mA, a maximum Zener impedance (ZZT) of 105 Ω at the test current, and a maximum reverse leakage current (IR) of 100 nA at a reverse voltage of 36 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation for general-purpose applications using a compact SOD-123 surface-mount package.
• Designed for automated board assembly with high-density layout capabilities.
• Offers robust electrostatic discharge protection rated at Class 3 (>16 kV) per the human body model.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix BT1G corresponds to the specific tape and reel packaging configuration required for your manufacturing line. Confirm that the component meets RoHS compliance standards if environmental regulations apply to your production environment. Ensure the supplier provides traceability documentation consistent with onsemi's quality assurance protocols.

Single Zener Diodes Selection Notes

Select this component when a precise 47 V reference is needed in a space-constrained design. The SOD-123 package offers a smaller footprint compared to traditional leaded alternatives. Consider the thermal derating curves provided in the datasheet to ensure reliable operation under varying ambient temperatures and load conditions.

Single Zener Diodes Part Context

This part belongs to the MMSZ52xxxT1G series of Zener voltage regulators from onsemi. The series covers a wide voltage range from 2.4 V to 110 V, allowing designers to standardize on a single package type across multiple circuit designs. The 'B' suffix indicates a standard ±5% tolerance on the nominal Zener voltage.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOD-123 packaged Zener diodes with a 47 V nominal voltage and 500 mW power rating. Verify pinout compatibility and electrical parameter tolerances before substitution.
