1N4751A-TAP

Overview

The Vishay 1N4751A-TAP is a silicon planar power Zener diode in the DO-41 (DO-204AL) axial through-hole package. It provides a nominal Zener voltage of 30 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1.3 W and operates within a junction temperature range up to 175 °C. Electrical characteristics include a test current of 8.5 mA, a maximum dynamic resistance of 40 Ω at the test current, and a maximum reverse leakage current of 5 µA at 22.8 V.

Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Designed for high-power stabilization and clipping applications
• Features a standard ±5% Zener voltage tolerance

Applications

• Voltage stabilization circuits
• Signal clipping circuits

Procurement Notes

Verify that the ordering suffix -TAP corresponds to the taped unit configuration containing 5000 units per ammopack. Confirm compliance with RoHS3 standards and ensure the component meets AEC-Q101 automotive qualification requirements if applicable to the specific design environment.

Selection Notes

Select this component when a 30 V reference or regulator is required in an axial leaded package. Ensure the circuit design accommodates the 1.3 W thermal dissipation limits and verify that the 40 Ω dynamic impedance aligns with the stability requirements of the target application.

Part Context

This part belongs to the Vishay 1N47xx series of single Zener diodes, which covers a wide voltage range from 3.3 V to 75 V. The series utilizes silicon planar construction and is housed in the standardized DO-41 package, providing a reliable solution for general-purpose discrete semiconductor voltage regulation tasks.

Replacement Considerations

Cross-reference with other manufacturers' 1N4751A equivalents. Verify that substitute parts match the 30 V nominal voltage, 1.3 W power rating, and DO-41 physical dimensions.
