1N4744A-TAP

Overview

The Vishay 1N4744A-TAP is a silicon planar power Zener diode in the DO-41 axial package. It provides a nominal Zener voltage of 15 V with a standard tolerance of ±5 %. The device dissipates up to 1300 mW and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 5 µA at 11.4 V, a dynamic resistance of 14 Ω at a test current of 17 mA, and a forward voltage of 1.2 V at 200 mA.

Feature Summary

• Designed for use in stabilizing and clipping circuits requiring high power ratings
• Utilizes silicon planar technology for robust voltage regulation
• Features a glass passivated junction housed in an axial leaded package

Applications

• Voltage stabilization
• Clipping circuits

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. Confirm compliance requirements against the latest Vishay documentation. Validate all electrical parameters for the target application environment before integration.

Selection Notes

Select this component when a 15 V reference point is required in through-hole designs. Ensure the thermal management strategy supports the 1300 mW dissipation rating under expected ambient conditions.

Part Context

This part belongs to the Vishay 1N4728A to 1N4761A series of single Zener diodes. The TAP suffix indicates availability in an ammo pack configuration containing 5000 units per reel.

Replacement Considerations

Cross-reference other manufacturers' DO-41 packages rated for 15 V and 1.3 W. Verify equivalent dynamic resistance and leakage specifications.
