1N4756A-TAP

Overview

The Vishay 1N4756A-TAP is a silicon planar power Zener diode in the DO-41 (DO-204AL) package. It provides a nominal Zener voltage of 47 V with a standard tolerance of ± 5 %. The device operates at a test current of 5.5 mA and features a maximum reverse leakage current of 5 μA at 35.8 V. Dynamic resistance is specified at 80 Ω, while surge current reaches 19 mA. Power dissipation is rated at 1300 mW, with a junction temperature limit of 175 °C.

Feature Summary

• Silicon planar construction for high-power stabilization and clipping applications
• Standard Zener voltage tolerance of ± 5 %
• Hermetically sealed glass body with axial leads

Applications

• Voltage stabilization circuits
• High power rating clipping circuits

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. The TAP designation indicates an ammopack format containing 5000 units per pack. Ensure compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a 47 V reference point is required within the 1N47xx series range. Consider the 1300 mW power dissipation capability and the 175 °C maximum junction temperature for thermal management. Verify that the 80 Ω dynamic impedance meets the circuit's regulation requirements.

Part Context

This part belongs to the Vishay 1N4728A through 1N4761A series of silicon planar power Zener diodes. The series covers a wide voltage range from 3.3 V to 75 V. All devices share the same DO-41 package and utilize double slug type construction for robust performance in demanding environments.

Replacement Considerations

Compatible substitutes include the 1N4756A-TR and other variants within the 1N4728A to 1N4761A series. Cross-reference electrical parameters such as Zener voltage and power dissipation to ensure functional equivalence.
