BZG05C47-HE3-TR

Single Zener Diodes Overview

The BZG05C47-HE3-TR is a unidirectional silicon Zener diode from the Vishay BZG05C-Series, housed in a DO-214AC (SMA) surface-mount package. It provides a nominal Zener voltage of 47 V with a tolerance range of 44 V to 50 V at a test current of 4 mA. The device features a maximum reverse leakage current of 36 µA at 36 V and a dynamic impedance of 90 Ω at 4 mA. Rated for a maximum power dissipation of 1250 mW at 25 °C, it supports a junction temperature up to 150 °C and is qualified under AEC-Q101 standards.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tape configuration, as the series is available in both 7-inch and 13-inch reels. Confirm the presence of the HE3 suffix to ensure AEC-Q101 automotive qualification is included. Cross-reference the manufacturer part number with official datasheets to validate RoHS compliance status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 47 V regulation point is required in a compact SMA footprint. Ensure the application environment does not exceed the 150 °C maximum junction temperature limit. Consider the thermal resistance characteristics based on the specific PCB copper overlay area to maintain safe operating conditions during continuous operation.

Single Zener Diodes Part Context

This component belongs to the BZG05C-Series of high-reliability Zener diodes manufactured by Vishay Semiconductors. The series covers a broad voltage spectrum from 3.3 V to 100 V within the same physical package form factor. This standardization simplifies inventory management and allows for consistent assembly processes across various voltage requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZG05C-series variants such as BZG05C47-E3-TR for commercial grade applications. Alternative packages like DO-214AB may require schematic adjustments due to dimensional differences.
