1N4754AGE3/TR

Overview

The Microchip Technology 1N4754AGE3/TR is a single silicon Zener diode rated for 1 W power dissipation. It provides a nominal Zener voltage of 39 V with a tolerance of +/- 5%. The device operates in the axial DO-41 package and supports a maximum operating temperature of +175 C. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 22 Ohms at the test current of 12.5 mA, and a forward voltage of 1.2 V.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Capable of handling 1 W continuous power dissipation
• Supports high-temperature operation up to +175 C
• Features low reverse leakage current for efficient blocking

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths
• Power supply regulation and stabilization

Procurement Notes

Verify the specific suffix 'e3' confirms RoHS compliance status as documented by the manufacturer. Confirm the 'TR' designation indicates reel packaging suitable for automated assembly processes. Cross-reference the exact part number against official Microchip databases to ensure availability and correct revision history before finalizing procurement orders.

Selection Notes

Select this component when a 39 V regulation point is required within a 1 W power budget. Ensure the circuit design accommodates the specified 12.5 mA test current for accurate voltage maintenance. Verify that the DO-41 axial package fits the mechanical constraints and that the +175 C thermal rating meets the operational environment requirements.

Part Context

This component belongs to the standard 1N47xx series of Zener diodes manufactured by Microchip Technology. These devices are widely utilized in general-purpose electronics for their reliability and standardized performance parameters. The 1N4754 variant specifically targets applications needing precise 39 V regulation with robust thermal capabilities.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4754 variants meeting identical 39 V, 1 W, and DO-41 specifications. Ensure any replacement maintains the same +/- 5% voltage tolerance and thermal ratings to guarantee circuit compatibility without redesign.
