BZM55C12-TR

Single Zener Diodes Overview

The BZM55C12-TR is a single silicon planar Zener diode from Vishay, housed in a hermetically sealed MicroMELF (SOD-80) surface-mount package. It provides a nominal Zener voltage of 12 V with a tolerance range of 11.4 V to 12.7 V at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a reverse leakage current of less than 0.1 µA at 2 V and dynamic resistance values under 20 Ω.

• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. The standard tape and reel configuration typically contains 2500 units per 7-inch reel. Ensure that the required minimum order quantity aligns with the supplier's distribution guidelines before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a compact, hermetically sealed Zener diode is required for precision voltage regulation. The C-series designation indicates a 5% voltage tolerance, suitable for applications demanding tighter specifications than the B-series. Confirm that the operating environment remains within the specified thermal limits to maintain performance integrity.

Single Zener Diodes Part Context

This part belongs to the BZM55-Series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide voltage range from 2.4 V to 75 V in a standardized MicroMELF package. These devices are designed as direct replacements for legacy components while providing improved mechanical robustness and consistent electrical performance across varying temperatures.

Single Zener Diodes Replacement Considerations

The datasheet states that electrical data is identical to the BZT55..series and TZM..series. Verify pinout compatibility and physical footprint dimensions when substituting these legacy parts.
