BZT52C3V9-7-F

Single Zener Diodes Overview

The BZT52C3V9-7-F is a surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOD123 package. It provides a nominal Zener voltage of 3.9 V with a tolerance range of 3.7 V to 4.1 V at a test current of 5 mA. The device features a maximum Zener impedance of 90 Ohms and a maximum reverse leakage current of 3.0 uA at 1.0 V. It supports a power dissipation of 500 mW at 75°C lead temperature and operates within a junction temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-7-F' confirms commercial grade qualification and 3,000-unit tape and reel packaging. Ensure the application environment remains within the specified thermal limits to maintain the rated 500 mW power dissipation capability. Confirm compliance with relevant regional environmental regulations prior to integration.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V reference or clamp is required in a compact SMD footprint. Consider the 90 Ohm impedance limit for dynamic regulation needs. Evaluate thermal derating requirements if ambient temperatures exceed standard operating conditions. Verify that the single-diode configuration meets the circuit polarity requirements.

Single Zener Diodes Part Context

This part belongs to the BZT52C series of surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.0 V to 51 V, all sharing the same SOD123 mechanical outline. The product line is designed for general-purpose use and automated manufacturing environments.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering SOD123 packaged Zener diodes with a 3.9 V nominal voltage and similar impedance characteristics. Verify pinout compatibility and thermal resistance values before substitution.
