1N4750A/TR

Overview

The Microchip Technology 1N4750A/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The component dissipates up to 1 W of power and operates within a temperature range of -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 is housed in an axial DO-41 package suitable for through-hole mounting.

Feature Summary

• Provides stable voltage regulation at a nominal 27 V level
• Capable of handling 1 W power dissipation in a compact axial package
• Ensures low leakage current for efficient circuit performance

Applications

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

Procurement Notes

Verify the specific manufacturer designation and suffix against official Microchip Technology documentation to confirm the exact part variant. Ensure the requested component matches the required voltage rating, power dissipation capabilities, and package type for your design. Cross-reference datasheets to validate compliance with environmental standards and operational temperature ranges before procurement.

Selection Notes

Select this component when a reliable 27 V regulation point is needed with moderate power handling. Consider the ±5% tolerance and 35 Ohm impedance for precision requirements. Verify that the axial DO-41 form factor fits the board layout constraints and that the operating temperature range aligns with the system environment.

Part Context

This device belongs to the standard Zener diode family used for maintaining constant voltage across varying loads. It serves as a fundamental passive component in power supplies and signal conditioning circuits. The axial leaded construction facilitates easy integration into traditional printed circuit board designs requiring robust voltage clamping or referencing.

Replacement Considerations

Substitutes must match the 27 V Zener voltage, 1 W power rating, and DO-41 package. Verify equivalent electrical parameters such as impedance and leakage current. Confirm thermal performance and regulatory compliance align with the original specification.
