1N3620

Single Diodes Overview

The Microchip Technology 1N3620 is a standard recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 25 A. The device exhibits a forward voltage drop of 1.1 V at 30 A and maintains a low reverse leakage current of 10 µA at 400 V. With a junction temperature range of -65°C to 200°C, it utilizes the DO-203AA (DO-4) axial leaded package for reliable terminal mounting.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of 200°C
• Robust mechanical construction using the DO-203AA axial leaded package
• Standard recovery characteristics suitable for general-purpose power conversion

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity and traceability. Confirm that the physical dimensions match the DO-203AA specification sheet before integration into the assembly process. Ensure storage conditions remain within specified limits to prevent degradation of the semiconductor junction prior to soldering.

Single Diodes Selection Notes

Select this component when a 400 V blocking capability and 25 A continuous current handling are required in a through-hole configuration. The 200°C junction rating provides superior thermal headroom compared to standard 175°C devices. Consider the DO-203AA footprint constraints and terminal mounting requirements during the PCB layout phase to ensure adequate clearance and mechanical support.

Single Diodes Part Context

This part belongs to the legacy 1N series of silicon rectifiers manufactured by Microchip Technology. These components are widely recognized in industrial electronics for their durability and standardized electrical characteristics. The 1N3620 specifically addresses high-current requirements where standard small-signal diodes would fail due to thermal or current limitations.

Single Diodes Replacement Considerations

Consult official Microchip documentation for verified equivalent part numbers. Cross-referencing with other manufacturers requires strict validation of the 400 V Vr, 25 A Io, and DO-203AA package compatibility.
