1N4711

Overview

The Microchip Technology 1N4711 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a standard tolerance of 5%. The device is rated for a power dissipation of 0.5 W and utilizes a DO-35 glass axial-leaded package. It operates within a temperature range of -65°C to +175°C, ensuring reliability in demanding environments.

Feature Summary

• Provides stable voltage regulation across a broad operating current range
• Features internal metallurgical bonding for enhanced structural integrity
• Constructed with a glass axial-leaded body for environmental protection

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify the specific suffix (e.g., C, UR) against design requirements, as variants differ in tolerance or package type. Confirm RoHS compliance status if restricted substances are prohibited. Cross-reference datasheet electrical characteristics to ensure compatibility with circuit load conditions and thermal management constraints before finalizing procurement.

Selection Notes

Select this component when a 27 V regulation point is required in a low-power through-hole application. Consider the 0.5 W power rating and DO-35 package dimensions for PCB layout. Evaluate tighter tolerance options if precision exceeds the standard 5% specification. Ensure the operating temperature range aligns with the system's environmental demands.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 0.5 W Zener voltage regulators. The series offers voltages from 1.8 V to 43 V in standard DO-35 packages. Variants include surface mount equivalents and military-grade screened versions, providing flexibility for diverse electronic design needs.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4711A or 1N4711B diodes. Verify pinout compatibility and ensure replacement devices meet the same 27 V Zener voltage and 0.5 W power dissipation ratings.
