BZT52H-A5V6X

Single Zener Diodes Overview

The Nexperia BZT52H-A5V6X is a general-purpose Zener diode belonging to the BZT52H series, housed in an SOD123F small and flat lead Surface-Mounted Device (SMD) plastic package. It provides a nominal working voltage of 5.6 V with a tight tolerance of ±1 %. The device supports a total power dissipation of up to 830 mW when mounted on an FR4 Printed-Circuit Board (PCB). Key electrical characteristics include a maximum differential resistance of 400 Ω at IZ = 1 mA and 40 Ω at IZ = 5 mA, alongside a reverse current of 1 µA maximum at VR = 5 V.

Single Zener Diodes Feature Summary

• Offers high-precision voltage regulation with ±1 % tolerance for sensitive circuit applications.
• Utilizes a compact SOD123F surface-mounted package suitable for high-density designs.
• Supports extended thermal performance with total power dissipation up to 830 mW on standard PCB footprints.

Single Zener Diodes Applications

• General voltage regulation functions
• Voltage reference circuits
• Over-voltage protection

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'X' aligns with the manufacturer's official ordering codes, as the datasheet primarily lists 'G3' for the BZT52H-A5V6 type. Confirm RoHS compliance and REACH status directly from the latest product documentation before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage stability is required, given its ±1 % tolerance compared to standard ±5 % variants. Ensure the design accommodates the thermal requirements, as power dissipation ratings depend heavily on the PCB copper area and mounting conditions specified in the thermal characteristics section.

Single Zener Diodes Part Context

This part belongs to the BZT52H series of voltage regulator diodes manufactured by Nexperia. The series encompasses a wide range of breakdown voltages from 2.4 V to 75 V across three tolerance grades: ±1 %, ±2 %, and approximately ±5 %. All types share the same SOD123F package and general structural features defined in the common data sheet.

Single Zener Diodes Replacement Considerations

The BZT52H-B5V6 serves as a direct alternative within the same series, offering a ±2 % tolerance instead of ±1 %. Other BZT52H series variants with identical or compatible voltage ratings may be considered if tolerance requirements allow.
