1N2827A

Overview

The Microchip Technology 1N2827A is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -55°C to +175°C. It utilizes the DO-204AH (DO-35) axial through-hole package, ensuring compatibility with standard PCB layouts. The component exhibits a maximum Zener impedance of 10 Ohms and maintains a reverse leakage current of 2 µA at 3 V.

Feature Summary

• Provides stable voltage regulation with a nominal 6.2 V output.
• Supports high-temperature operation up to 175°C junction temperature.
• Utilizes a robust glass passivated junction for reliability.
• Offers low Zener impedance for effective noise filtering.

Applications

• Voltage reference circuits in precision measurement systems
• Overvoltage protection stages in power supply inputs
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid traceability records. Confirm that the received components match the specified DO-204AH package dimensions and lead finish requirements before integration into production assemblies.

Selection Notes

Select this component when a 6.2 V regulation point is required in space-constrained through-hole designs. The 500 mW rating suits moderate current applications without requiring external heat sinking. Consider the ±5% tolerance for budgeting voltage accuracy in the final system design. Evaluate the thermal environment to ensure the 175°C limit is not exceeded during continuous operation.

Part Context

This part belongs to the standard 1N series of Zener diodes manufactured by Microchip Technology. These components are widely used in general-purpose electronics for basic voltage stabilization tasks. The 1N2827A specifically addresses the common need for a 6.2 V reference in legacy and modern mixed-signal circuits alike.

Replacement Considerations

Direct substitutes include other manufacturers' 1N2827A equivalents meeting the same JEDEC specifications. Cross-referencing should verify identical voltage, power, and package parameters. Alternative Microchip variants like the 1N827A may offer similar performance but require confirmation of suffix-specific differences.
