1N4757AHB0G

Overview

The 1N4757AHB0G is a single Zener diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in the DO-204AL (DO-41) package. It features a nominal Zener voltage of 51 V with a tolerance of ±5% and a power dissipation rating of 1 W. The device exhibits a maximum reverse leakage current of 5 µA at a reverse bias of 38.8 V. This component belongs to the Automotive series and holds AEC-Q101 qualification, ensuring reliability for automotive applications.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Low reverse leakage current characteristic
• Through-hole DO-204AL package construction

Applications

• Automotive electronic circuits
• Voltage regulation systems
• Overvoltage protection applications

Procurement Notes

Verify the specific suffix 'B0G' against the manufacturer's official datasheet to confirm exact packaging and compliance details. Ensure the procurement channel provides valid traceability documentation. Confirm RoHS3 compliance status directly with the supplier or original manufacturer before finalizing orders to meet regulatory requirements.

Selection Notes

Select this component when a 51 V Zener reference is required in an automotive environment. The DO-204AL package suits high-power through-hole designs. Verify that the 1 W power rating and ±5% voltage tolerance align with the circuit's thermal and precision constraints. Consider the low leakage current for sensitive signal paths.

Part Context

This part is part of Taiwan Semiconductor's broader portfolio of Zener diodes, specifically targeting the automotive sector. It shares the standard 1N47xx series designation but includes specific manufacturing qualifications. The 'AHB0G' suffix indicates specific material and packaging attributes defined by the manufacturer for this particular variant.

Replacement Considerations

Cross-reference with other 1N4757A variants from different manufacturers only if they explicitly state AEC-Q101 qualification and identical DO-204AL pinout compatibility. Verify that substitute parts match the 51 V nominal voltage and 1 W power dissipation ratings exactly.
