1N4750A

Overview

The Microchip Technology 1N4750A is a silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device 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 forward voltage of 1.2 V at 200 mA. It is housed in the DO-41 axial through-hole package.

Feature Summary

• Provides stable voltage regulation using silicon planar technology
• Features hermetic glass encapsulation for environmental protection
• Designed for high thermal resistance and reliable operation

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status as specific suffixes may vary. Ensure the DO-41 package dimensions match your PCB footprint requirements before procurement.

Selection Notes

Select this component when a precise 27 V regulation point is required with low leakage current specifications. Consider the 1 W power dissipation limit and the operating temperature range relative to your system's thermal environment. Verify that the axial leaded package fits your assembly constraints.

Part Context

This part belongs to the standard 1N47xx series of 1-watt Zener diodes. It serves as a fundamental discrete semiconductor component for basic electronic circuit design. The 1N4750A designation specifically identifies the 27-volt variant within this widely used family of voltage regulators.

Replacement Considerations

Compatible substitutes include the 1N4750AGE3 from Microchip Technology and the 1N4750A-B from Rectron. These alternatives share identical electrical ratings and the DO-41 package form factor.
