1N4761A-TAP

Overview

The Vishay 1N4761A-TAP is a silicon planar power Zener diode in the 1N4728A to 1N4761A series, housed in an axial DO-41 (DO-204AL) package. It provides a nominal Zener voltage of 75 V with a standard tolerance of ± 5 %. The device operates at a test current of 3.3 mA and dissipates up to 1300 mW of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 56 V and a dynamic impedance of 175 Ω at the test current. It supports a surge current of 2000 mA and functions within a junction temperature range of -65 °C to +175 °C.

Feature Summary

Procurement Notes

Verify that the ordering suffix '-TAP' corresponds to the specific ammopack packaging configuration containing 5000 units per reel as defined in the official Vishay documentation. Confirm compliance requirements against the material categorization definitions provided in the manufacturer's reference documents before finalizing procurement specifications.

Selection Notes

Select this component when a 75 V reference is required in an axial through-hole format. Ensure the circuit design accommodates the specified 175 Ω dynamic impedance and 5 µA leakage limits. Verify thermal management capabilities to maintain operation within the 175 °C junction temperature limit during continuous power dissipation.

Part Context

This part belongs to the Vishay 1N47xxA series of single Zener diodes, which covers a voltage range from 3.3 V to 100 V. The series utilizes a standardized DO-41 package and offers consistent performance characteristics across the voltage spectrum, making it suitable for general-purpose discrete semiconductor applications requiring reliable voltage regulation.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4761A equivalents in the DO-41 package. Verify that substitute components match the 75 V nominal voltage, ± 5 % tolerance, and 1300 mW power dissipation ratings to ensure functional compatibility.
