1N4751AHA0G

Overview

The Taiwan Semiconductor 1N4751AHA0G is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 30 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range from -55 °C to +150 °C. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 50 Ohms, and a test current of 7 mA. It utilizes a DO-41-2 through-hole package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetic sealing suitable for high reliability applications requiring source control drawings
• Complies with AEC-Q101 automotive qualification standards

Applications

• Voltage regulation in automotive electronic systems
• High reliability circuits requiring hermetic sealing
• Industrial equipment protected by source control drawings

Procurement Notes

Verify the specific suffix 'A0G' against official Taiwan Semiconductor documentation to confirm exact manufacturing lot details and compliance status. Confirm that the AEC-Q101 qualification aligns with your project's automotive requirements. Ensure the DO-41-2 package dimensions match your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 30 V reference is required in a through-hole configuration with strict reliability standards. The AEC-Q101 certification makes it suitable for automotive environments where standard commercial parts may fail. Compare the 50 Ohm impedance against circuit sensitivity requirements to ensure adequate regulation performance under varying load conditions.

Part Context

This part belongs to the 1N4751AH series, which offers hermetically sealed glass encapsulation for enhanced durability. The 'A' suffix indicates a 5% voltage tolerance, while the 'H' denotes the hermetic seal. This series provides a robust alternative to plastic-encapsulated variants for demanding industrial or aerospace applications.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4751A variants with hermetic seals, such as Microsemi MX1N4751APTR or MCC 1N4751A-AP. Verify that replacement parts maintain the same DO-41 package footprint and AEC-Q101 qualification if automotive use is intended.
