BZM55C62-TR

Single Zener Diodes Overview

The BZM55C62-TR is a hermetically sealed silicon planar Zener diode from Vishay, packaged in the MicroMELF (SOD-80) surface-mount format. It provides a nominal Zener voltage of 62 V with a test current of 2.5 mA and a maximum power dissipation of 500 mW. The device features a reverse leakage current of less than 10 µA at 47 V and a dynamic resistance of 150 Ω at 1 kHz. Operating within a junction temperature range of -65 °C to +175 °C, it exhibits a positive temperature coefficient of 0.04 %/K.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm reel specifications. Confirm that the component meets RoHS compliance requirements and material categorization standards before finalizing procurement. Ensure the package type matches the intended footprint design.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 62 V is required in a compact surface-mount environment. Consider the positive temperature coefficient for thermal compensation needs. Evaluate the 500 mW power dissipation limit relative to the expected operating current and ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the BZM55 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers electrical data identical to the BZT55 and TZM series but utilizes the smaller MicroMELF package. It is designed for applications requiring high stability and low noise in a space-saving form factor.

Single Zener Diodes Replacement Considerations

The datasheet indicates that electrical data is identical to the BZT55..series and TZM..series devices. Verify pinout compatibility and package dimensions before substituting these parts.
