BZV49-C68,115

Single Zener Diodes Overview

The BZV49-C68,115 is a medium-power voltage regulator diode from the Nexperia BZV49 series, housed in a SOT-89 plastic surface-mount package. It provides a nominal working voltage of 68 V with an approximate ±5% tolerance range. The device supports a maximum total power dissipation of 1 W and can withstand non-repetitive peak reverse power dissipation up to 40 W. Electrical characteristics include a test current (IZtest) of 2 mA, a differential resistance (rdif) ranging from 65.6 Ω to 79.8 Ω, and a temperature coefficient between 65.6 mV/K and 79.8 mV/K at the test current.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable voltage reference or protection near 68 V. Ensure the circuit design accommodates the specified differential resistance and temperature coefficient variations. Confirm that the SOT-89 package footprint aligns with the PCB layout requirements and that the 1 W power dissipation limit is not exceeded under worst-case thermal conditions.

Single Zener Diodes Part Context

This part belongs to the BZV49 series of voltage regulator diodes manufactured by Nexperia USA Inc. The series comprises 37 types covering nominal working voltages from 2.4 V to 75 V. These devices are designed for general regulation purposes and utilize a standardized SOT-89 package to facilitate efficient heat transfer through the collector pad.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 68 V nominal voltage, SOT-89 package, and 1 W power rating. Verify compatibility regarding tolerance, differential resistance, and thermal characteristics against the original design specifications.
