1N4760A-T

Overview

The Vishay 1N4760A-T is a single silicon unidirectional Zener diode housed in the DO-41 axial leaded package. It provides a nominal Zener voltage of 68 V with a 5% tolerance at a test current of 3.7 mA. The device supports a maximum power dissipation of 1.3 W and operates within a temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 150 Ohms, and a knee impedance of up to 2000 Ω.

Feature Summary

• Provides stable voltage regulation using a single silicon junction structure
• Features high thermal stability suitable for wide operating temperature ranges
• Utilizes glass encapsulation for environmental protection

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for signal lines

Procurement Notes

Verify the specific suffix 'T' against official Vishay documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required 1.3 W power rating and DO-41 form factor. Cross-reference RoHS compliance status directly with the manufacturer's latest product change notices before procurement.

Selection Notes

Select this component when a 68 V regulation point is required in an axial through-hole configuration. Compare the 1.3 W dissipation capability against circuit load requirements. Evaluate the 150 Ohm dynamic impedance for noise sensitivity needs. Confirm that the 5% voltage tolerance aligns with system precision constraints.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes manufactured by Vishay General Semiconductor. These components are widely used in general-purpose electronics for basic voltage regulation tasks. The DO-41 package offers a robust mechanical solution for through-hole mounting on printed circuit boards.

Replacement Considerations

Equivalent parts from other manufacturers include STMicroelectronics 1N4760A and Fairchild 1N4760A. Verify pinout compatibility and ensure the replacement maintains the same 68 V nominal voltage and 1.3 W power rating.
