1N4627

Overview

The Microchip Technology 1N4627 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a power dissipation rating of 500 mW. The device utilizes a DO-204AH (DO-35) axial through-hole package and offers a voltage tolerance of ±5%. Electrical characteristics include a maximum Zener impedance of 15 Ohms and a reverse leakage current of 2 µA at 3 V. It operates within a temperature range of -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation via Zener breakdown mechanism
• Capable of handling high thermal stress up to 175°C junction temperature
• Constructed in a robust axial leaded package for through-hole mounting

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clamping applications in signal conditioning

Procurement Notes

Verify the specific manufacturer lot and compliance status, as this component may be classified under military or space-grade specifications depending on the suffix. Confirm RoHS exemption requirements if applicable to your assembly process. Ensure the ordering part number matches the exact tolerance and packaging format required by your design specifications.

Selection Notes

Select this component when a precise 6.2 V reference is needed in a standard axial package. Consider the 15 Ohm impedance value for dynamic load variations. Evaluate the 500 mW power limit against expected surge currents. Compare against other 1N46xx series variants if different voltage levels are required.

Part Context

This part belongs to the 1N4627 series of Zener diodes manufactured by Microchip Technology. It serves as a discrete semiconductor solution for maintaining constant voltage levels in electronic circuits. The DO-35 package provides a compact footprint suitable for general-purpose electronics and industrial equipment requiring reliable voltage clamping.

Replacement Considerations

Direct substitutes include the 1N824 from Microchip Technology, which shares identical electrical parameters and package type.
