1N4754A-TAP

Overview

The Vishay 1N4754A-TAP is a silicon planar power Zener diode designed for voltage stabilization and clipping applications. It features a nominal Zener voltage of 39 V with a standard tolerance of ±5 %. The device operates within a test current range of 6.5 mA and exhibits a maximum reverse leakage current of 5 µA at 29.7 V. It provides a dynamic resistance of 60 Ω at the test current and supports a surge current of 115 mA. The component is housed in a DO-41 (DO-204AL) through-hole package, rated for a maximum junction temperature of 175 °C.

Feature Summary

• Utilizes silicon planar technology for robust power handling in stabilizing and clipping circuits
• Provides precise voltage regulation with a standard Zener voltage tolerance of ±5 %
• Engineered for high thermal stability with a maximum junction temperature rating of 175 °C

Applications

• Voltage stabilization
• Clipping circuits

Procurement Notes

Verify that the ordering suffix -TAP corresponds to the specific ammopack packaging configuration containing 5000 units per pack. Confirm compliance requirements against the material categorization definitions provided by Vishay. Ensure the selected variant matches the required electrical characteristics for the intended circuit design before finalizing procurement.

Selection Notes

Select this component when a 39 V reference is required in through-hole designs. The DO-41 package accommodates standard PCB layouts. Verify that the 1.3 W power dissipation capability meets the thermal requirements of the application under expected ambient conditions. Check that the 60 Ω dynamic resistance aligns with the noise and regulation specifications of the target circuit.

Part Context

This part belongs to the Vishay 1N4728A to 1N4761A series of single Zener diodes. The series covers a broad nominal voltage range from 3.3 V to 75 V. All devices in this family share the same DO-41 glass case material and UL 94 V-0 flammability rating. They are manufactured using silicon planar processes optimized for high power ratings.

Replacement Considerations

Cross-reference other manufacturers' 1N4754A equivalents to ensure pinout compatibility and matching electrical tolerances. Verify that substitute components maintain the same DO-41 footprint and lead spacing to fit existing board layouts without modification.
