BZV55C43

Single Zener Diodes Overview

The BZV55C43 is a single silicon planar Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA (SOD-80) package. It features a nominal Zener voltage of 43 V with a tolerance of ±7%. The device operates within a temperature range of -65°C to +175°C and has a maximum power dissipation of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 50 nA at the test current of 2 mA, a Zener impedance of 130 Ohms, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Surface-mount construction in a compact DO-213AA package for automated assembly
• High thermal stability supporting operation up to 175°C junction temperature
• Low leakage current specification for precision voltage reference applications

Single Zener Diodes Applications

• Overvoltage protection for sensitive input lines
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the BZV55 series may be produced by various authorized partners under license. Confirm RoHS compliance status and exact packaging configuration (reel vs. tape) prior to ordering, as these details vary by production batch and supplier. Ensure the component matches the required voltage tolerance and package dimensions for your PCB layout.

Single Zener Diodes Selection Notes

Select this component when a 43 V Zener voltage is required in a small surface-mount footprint. Consider the 500 mW power rating and 130 Ohm impedance for circuit design calculations. Verify that the operating temperature range meets the environmental requirements of the final application, particularly regarding the high maximum junction temperature capability.

Single Zener Diodes Part Context

This part belongs to the BZV55 series of single Zener diodes, which are widely used for general-purpose voltage regulation. The series offers various voltage options in the same DO-213AA package, allowing for standardized inventory management across different voltage requirements in consumer and industrial electronics designs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include BZV55C43/TR from Microchip Technology or equivalent parts from other manufacturers such as Taiwan Semiconductor, provided they match the 43 V nominal voltage, DO-213AA package, and electrical specifications.
