BZT52C3V9-TP

Single Zener Diodes Overview

The BZT52C3V9-TP is a single Zener diode manufactured by Micro Commercial Components (MCC) in the SOD-123 surface-mount package. It features a nominal Zener voltage of 3.9 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a test current of 5 mA, a maximum Zener impedance of 90 Ohms at this current, and a maximum reverse leakage current of 3 µA at 1.0 V. The forward voltage is typically 0.9 V at a forward current of 10 mA.

Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm the specific suffix indicates RoHS compliance. Ensure the ordering quantity matches the standard tape and reel packaging specifications provided by the manufacturer.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 3.9 V reference with 500 mW power handling capability in an SOD-123 footprint. Consider the 90 Ohm impedance and 3 µA leakage current when designing precision circuits. Verify thermal management requirements against the 250°C/W junction-to-ambient thermal resistance rating.

Single Zener Diodes Part Context

This part belongs to the BZT52C series of 500 mW Zener diodes ranging from 2.0 V to 75 V. All devices in this series share the same SOD-123 package dimensions and general physical characteristics while differing in specific electrical parameters such as breakdown voltage and impedance.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZT52C3V6-TP and BZT52C4V3-TP. Cross-manufacturer equivalents must match the SOD-123 package, 500 mW power rating, and 3.9 V nominal voltage specification.
