1N4750AGE3/TR

Overview

The 1N4750AGE3/TR is a single silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of 5 percent and a power dissipation rating of 1 W. The device operates within an extended temperature range from -65 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 35 Ohms, and a test current of 9.5 mA. It utilizes the DO-41 axial package and is supplied in reel packaging.

Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction.
• Features hermetic-sealed glass encapsulation for enhanced environmental protection.
• Supports operation across a wide industrial temperature range up to 175 °C.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify the specific suffix 'AG' indicates the hermetically sealed glass variant distinct from plastic packages. Confirm the 'e3' suffix denotes lead-free compliance and RoHS status. Ensure the 'TR' designation matches the required reel quantity for automated assembly processes. Cross-reference the manufacturer part number against official datasheets to validate all electrical parameters before integration.

Selection Notes

Select this component when high-temperature stability and hermetic sealing are required for critical voltage regulation. The 1 W power rating supports moderate current loads compared to lower-power alternatives. The 5 percent tolerance offers standard precision suitable for general applications. Consider the axial DO-41 form factor for through-hole mounting requirements.

Part Context

This device belongs to the popular 1N47xx series of 1.0 watt Zener diodes produced by Microchip. The series covers a broad voltage selection range from 3.3 to 100 volts. The AG suffix specifically identifies the hermetically sealed glass body version, which provides higher rated temperatures and reliability compared to the standard plastic encapsulated variants within the same JEDEC numbering system.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4750A devices meeting identical 27 V and 1 W specifications. Hermetically sealed equivalents with the G suffix may be considered if glass encapsulation is mandatory. Verify that any replacement maintains the DO-41 package dimensions and thermal performance limits.
