1N4741A-TAP

Overview

The Vishay 1N4741A-TAP is a silicon planar power Zener diode in the DO-41 (DO-204AL) axial package. It provides an 11 V nominal Zener voltage with a ±5% tolerance. The device dissipates up to 1300 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 5 µA, a dynamic resistance of 8 Ω at the test current of 23 mA, and a forward voltage of 1.2 V at 200 mA.

Feature Summary

• Silicon planar construction for high-power stabilization and clipping applications
• Standardized ±5% Zener voltage tolerance for consistent circuit performance
• High thermal stability supporting operation up to 175 °C junction temperature

Applications

• Voltage stabilization circuits
• Signal clipping applications

Procurement Notes

Verify the specific manufacturer datasheet revision and electrical parameters against the official Vishay documentation prior to procurement. Confirm that the TAP suffix corresponds to the required ammopack packaging format. Ensure compliance requirements align with project specifications before finalizing orders.

Selection Notes

Select this component when an 11 V reference or regulation point is required in through-hole designs. The DO-41 package accommodates standard PCB layouts while providing sufficient power handling for general-purpose voltage regulation tasks without requiring complex heat sinking.

Part Context

This part belongs to the Vishay 1N4728A to 1N4761A series of single Zener diodes. The series covers a broad voltage range from 3.3 V to 75 V, utilizing identical DO-41 packages and standardized electrical testing conditions across all variants.

Replacement Considerations

Cross-reference other manufacturers' 1N4741A equivalents using the official Vishay datasheet to verify matching Zener voltage, power dissipation, and package dimensions.
