1N4758A-TAP

Overview

The Vishay General Semiconductor - Diodes Division 1N4758A-TAP is a silicon planar power Zener diode designed for stabilizing and clipping circuits. It features a nominal Zener voltage of 56 V with a standard tolerance of ±5%. The device operates in the DO-41 (DO-204AL) axial through-hole package, supporting a maximum power dissipation of 1300 mW at thermal equilibrium. Key electrical characteristics include a test current of 4.5 mA, a reverse leakage current of 5 µA at 42.6 V, and a dynamic resistance of 110 Ω at the test current.

Feature Summary

• Silicon planar construction optimized for high-power stabilization and clipping applications
• Standard Zener voltage tolerance of ±5% ensures consistent regulatory performance
• Robust thermal management capabilities with a junction temperature rating up to 175 °C

Applications

• Voltage stabilization in electronic circuits
• Signal clipping applications requiring high power ratings

Procurement Notes

Verify that the ordering code suffix matches the required packaging format, as the TAP designation indicates an ammopack configuration. Confirm compliance requirements against the material categorization definitions provided by the manufacturer. Ensure the component meets specific automotive or industrial qualification standards if applicable to the target design environment.

Selection Notes

Select this component when a 56 V regulation point is required within the 1N47xx series range. Consider the 1300 mW power dissipation limit relative to ambient temperature conditions. Evaluate the DO-41 package dimensions against available board space constraints. Verify that the 110 Ω dynamic resistance aligns with the circuit's stability requirements.

Part Context

This part belongs to the 1N4728A to 1N4761A series of silicon planar power Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 3.3 V to 75 V, providing standardized options for various power regulation needs. The 1N4758A variant specifically addresses the 56 V segment of this extensive product line.

Replacement Considerations

Direct substitutes within the same Vishay series include other 1N47xx variants with matching voltage ratings. Cross-manufacturer replacements must match the 56 V nominal voltage, 1 W minimum power rating, and DO-41 package footprint. Verify equivalent dynamic resistance and leakage current specifications before implementation.
