BZT52H-B43,115

Single Zener Diodes Overview

The Nexperia BZT52H-B43,115 is a general-purpose Zener diode housed in an SOD123F small and flat lead Surface-Mounted Device plastic package. It provides a nominal working voltage of 43 V with a ±2 % tolerance series. The device supports a total power dissipation of up to 830 mW at ambient temperatures ≤ 25 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a maximum differential resistance of 325 Ω at 2 mA, and a reverse current of 80 µA at the maximum rated reverse voltage.

Single Zener Diodes Feature Summary

• Small plastic package suitable for surface-mounted design
• Wide working voltage range from nominal 2.4 V to 75 V
• Three tolerance series: ±1 %, ±2 % and approximately ±5 %

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix '115' against the manufacturer's latest ordering information to confirm packaging details. Confirm that the component meets RoHS3 compliance requirements for your target market. Ensure the procurement source is an authorized distributor to guarantee authenticity and traceability of the Nexperia product.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V reference is required within a compact footprint. The ±2 % tolerance offers tighter voltage accuracy compared to standard ±5 % variants. Verify that the thermal management on the PCB can handle the 830 mW dissipation rating under expected operating conditions.

Single Zener Diodes Part Context

This part belongs to the BZT52H series of voltage regulator diodes manufactured by Nexperia USA Inc. The series comprises 111 types with 37 breakdown voltages, designed for high-density circuit designs. The BZT52H-B43,115 specifically utilizes the 'B' designation indicating the ±2 % tolerance band within the SOD123F package family.

Single Zener Diodes Replacement Considerations

Cross-reference with other BZT52H-B43 variants from different manufacturers if pin compatibility is critical. Ensure replacement parts match the SOD123F package dimensions and the 43 V nominal voltage specification.
