MMBZ5260C-TP

Single Zener Diodes Overview

The MMBZ5260C-TP is a single Zener diode from Micro Commercial Components, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 43 V with a standard tolerance of ±2%. The device supports a maximum power dissipation of 350 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a test current (IZT) of 3 mA, a maximum Zener impedance (ZZT) of 93 Ω at the test current, and a reverse leakage current (IR) of 0.1 µA at 33 V. The component features a lead-free finish and meets UL 94 V-0 flammability ratings.

Single Zener Diodes Feature Summary

• Offers high precision with a standard ±2% Zener voltage tolerance for stable reference applications.
• Utilizes a compact SOT-23 surface-mount package suitable for space-constrained designs.
• Constructed as a halogen-free 'Green' device compliant with RoHS standards.

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise reference levels.
• Over-voltage protection stages in portable electronics.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors to ensure traceability and quality. Confirm that the ordering suffix '-TP' corresponds to the Tape & Reel packaging format containing 3000 pieces per reel. Ensure the specific part number matches the required 43 V nominal voltage specification before integration.

Single Zener Diodes Selection Notes

Select this component when a tight ±2% voltage tolerance is critical for circuit accuracy. The 350 mW power rating allows for moderate current handling in small packages. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature range to maintain performance stability and reliability.

Single Zener Diodes Part Context

This part belongs to the MMBZ5229C through MMBZ5262C series, which covers a wide Zener voltage range from 4.3 V to 51 V. All devices in this family share the same SOT-23 footprint and general mechanical characteristics, differing primarily in their specific breakdown voltage and associated impedance values defined in the electrical characteristics table.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 43 V nominal voltage, ±2% tolerance, SOT-23 package, and 350 mW power rating. Verify that alternative components meet the same ZZT and IR specifications to ensure equivalent circuit behavior without redesigning the surrounding bias network.
