BZM55B68-TR

Single Zener Diodes Overview

The BZM55B68-TR is a small signal Zener diode from Vishay Semiconductors, featuring a nominal voltage of 68 V with a ±2% tolerance. It operates within a range of 66.6 V to 69.4 V at a test current of 2.5 mA. The device dissipates up to 500 mW and exhibits low reverse leakage (≤ 10 µA) and dynamic resistance (≤ 200 Ω). Packaged in a hermetically sealed MicroMELF (SOD-80) surface-mount format, it supports an operating junction temperature up to 175 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging details. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the supplier provides valid traceability documents matching the Vishay General Semiconductor - Diodes Division part number.

Single Zener Diodes Selection Notes

Select this component when a tight voltage tolerance is required compared to standard C-grade devices. The B-grade designation ensures a narrower voltage band around the nominal value. Consider the MicroMELF package dimensions for space-constrained printed circuit board layouts requiring high reliability.

Single Zener Diodes Part Context

This component belongs to the BZM55-Series of small signal Zener diodes manufactured by Vishay. The series utilizes a MicroMELF package designed to save space while maintaining electrical data identical to larger through-hole devices like the BZT55 and TZM series.

Single Zener Diodes Replacement Considerations

The datasheet indicates electrical data is identical to the BZT55..series and TZM..series devices.
