1N4768/TR

Overview

The Microchip Technology 1N4768/TR is a temperature-compensated Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The component has a power dissipation rating of 500 mW and operates within a temperature range of -65°C to +175°C. Packaged in the DO-204AH (DO-35) through-hole format, it includes a test current specification of 5 mA and a maximum reverse leakage current of 1 µA at 7.5 V.

Feature Summary

• Temperature compensated design ensures stable voltage regulation across varying thermal conditions
• Through-hole mounting configuration suitable for standard PCB assembly processes
• High operating temperature capability extending up to +175°C for demanding environments

Applications

• Precision voltage reference circuits requiring thermal stability
• Overvoltage protection in sensitive electronic systems
• Voltage regulator designs in industrial control equipment

Procurement Notes

Verify the specific suffix /TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status directly with the manufacturer or authorized distributor as regulatory requirements may vary by region. Ensure the requested quantity aligns with minimum order quantities defined by the supply chain partner. Validate that the DO-204AH package dimensions match your board layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable 9.1 V reference is required under fluctuating thermal loads. The temperature compensation feature distinguishes it from standard Zener diodes, making it suitable for high-precision analog circuits. Consider the 500 mW power rating to ensure adequate thermal management within the enclosure. Verify that the through-hole form factor fits the intended manufacturing process.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings and power dissipation levels. The /TR suffix denotes reel packaging, facilitating automated placement. This specific model focuses on temperature stability rather than high-power handling.

Replacement Considerations

Direct substitutes must match the 9.1 V Zener voltage, 500 mW power rating, and temperature-compensated characteristics. Verify pinout compatibility with the DO-204AH package. Check if alternative manufacturers offer equivalent thermal compensation curves for critical precision applications.
