BZM55C15-TR3

Single Zener Diodes Overview

The BZM55C15-TR3 is a single small signal Zener diode from Vishay Semiconductors, housed in the MicroMELF (SOD-80) surface-mount package. It features a nominal Zener voltage of 15 V with a tolerance range of 13.8 V to 15.6 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, a dynamic resistance of 30 Ω at 5 mA, and a temperature coefficient of 0.03 %/K at 25 °C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR3 corresponds to the 10,000 units per reel tape configuration on a 13-inch reel as specified in the manufacturer's ordering information. Confirm compliance requirements including RoHS directive 2002/95/EC and WEEE 2002/96/EC alignment during procurement processing.

Single Zener Diodes Selection Notes

Select this component when space-saving hermetic packaging is required alongside electrical equivalence to legacy TO-213AA devices. Ensure the application circuit accommodates the 500 mW power dissipation limit and verify that the 15 V nominal voltage aligns with the system reference requirements.

Single Zener Diodes Part Context

This part belongs to the BZM55-Series of small signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes the MicroMELF package to provide a compact alternative to traditional axial leads while maintaining hermetic sealing. The product line covers a wide Zener voltage range from 2.4 V to 75 V.
