BZG05C47TR3

Single Zener Diodes Overview

The BZG05C47TR3 is a single Zener diode from the Vishay BZG05C-Series, housed in a DO-214AC (SMA) surface-mount package. It features a nominal Zener voltage of 47 V with a test current of 0.25 mA and a maximum dynamic resistance of 90 Ohms at this current. The device supports a non-repetitive peak surge power dissipation of 60 W for 100 μs pulses and operates within a junction temperature range up to 150 °C. It is available in RoHS-compliant commercial grade (E3 suffix) or AEC-Q101 qualified automotive grade (HE3 suffix).

Single Zener Diodes Feature Summary

• AEC-Q101 qualified automotive-grade variants are available for enhanced reliability.
• Designed to fit onto standard 5 mm SMD footpads for compact layouts.
• Compatible with both wave and reflow soldering processes.

Single Zener Diodes Applications

• Voltage stabilization circuits
• Surge protection applications

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix to confirm compliance requirements. The -E3 suffix indicates RoHS-compliant commercial grade, while the -HE3 suffix denotes AEC-Q101 qualified automotive grade. Confirm that the TR3 designation corresponds to the 6000 units per 13-inch reel packaging format specified in the datasheet.

Single Zener Diodes Selection Notes

Select this component based on the required 47 V nominal breakdown voltage and the 0.25 mA test current condition. Ensure the application can accommodate the 90 Ohms maximum dynamic resistance. Verify thermal management capabilities against the 150 °C maximum junction temperature rating and the specific power dissipation limits defined by the board's thermal resistance.

Single Zener Diodes Part Context

This part belongs to the BZG05C-Series of Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series covers a wide voltage range from 3.3 V to 100 V and utilizes the DO-214AC surface-mount package. The product line includes options for both commercial and automotive qualification levels.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZG05C-series variants such as BZG05C47-M3-08 or BZG05C47-HM3-08, provided they match the required voltage tolerance and package type. Cross-brand replacements must be verified against the DO-214AC footprint and electrical specifications.
