1N4760AP/TR8

Overview

The 1N4760AP/TR8 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 68 V with a tolerance of ±5%. The device operates in the DO-41 (DO-204AL) axial through-hole package and dissipates up to 1 W of power. Key electrical parameters include a maximum dynamic impedance of 150 Ω at a test current of 3.7 mA, a maximum reverse leakage current of 5 µA, and an operating temperature range from -65 °C to +150 °C.

Feature Summary

• Provides stable voltage regulation using Zener breakdown characteristics
• Capable of handling high thermal loads with a 1 W power dissipation rating
• Designed for reliable operation across extreme ambient temperatures

Applications

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

Procurement Notes

Verify the specific suffix TR8 indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the DO-41 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 68 V regulation point is required within a through-hole design constraint. The 150 Ω dynamic impedance suits applications where moderate load regulation is acceptable. Consider the axial lead form factor for manual assembly or legacy board layouts that do not support surface-mount technologies.

Part Context

This part belongs to the standard 1N47xx series of silicon Zener diodes, widely utilized for basic voltage regulation tasks. The AP designation typically denotes specific tolerance and testing criteria defined by the manufacturer. The TR8 suffix identifies the reel quantity and packaging method used for automated insertion equipment.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4760 variants, such as STMicroelectronics or Continental Device India Limited. Verify that substitute parts maintain the same 68 V nominal voltage, 1 W power rating, and DO-41 package outline to ensure mechanical and electrical compatibility.
