1N4247

Overview

The Microchip Technology 1N4247 is a standard recovery rectifier diode designed for through-hole mounting in an A-Package-2 axial leaded configuration. It features a maximum repetitive peak reverse voltage of 600 V and supports a continuous forward current of 1 A. The device exhibits a forward voltage drop of 1.3 V at 3 A and a maximum reverse leakage current of 1 uA at 600 V. Key electrical characteristics include a 5 us reverse recovery time and a maximum surge current rating of 25 A. It operates within a junction temperature range of -65 C to +175 C.

Feature Summary

• Qualified per MIL-PRF-19500/286 standards for Level 1 devices
• Voidless hermetically sealed glass construction
• Standard recovery performance suitable for general-purpose applications

Applications

• Military electronic systems requiring qualified components
• High-reliability power supply circuits
• Industrial control equipment

Procurement Notes

Verify the specific revision level and lot traceability against the current Microchip datasheet before procurement. Confirm that the package designation matches the required mechanical footprint for your assembly process. Ensure compliance with relevant military specifications if the application demands MIL-PRF-19500/286 qualification. Check for any recent product change notifications that may affect material composition or testing procedures.

Selection Notes

Select this component when high voltage blocking capability and robust thermal performance are required. The wide operating temperature range makes it suitable for harsh environments. Consider the axial leaded package for manual insertion or specific board layouts where surface mount options are not viable. Evaluate the reverse recovery time against switching frequency requirements to ensure adequate circuit performance.

Part Context

This part belongs to the 1N4245 through 1N4249 series of JAN rectifiers manufactured by Microchip Technology. These components are specifically engineered for defense and aerospace sectors. The series shares similar physical dimensions but varies in voltage ratings. The 1N4247 provides a balanced specification set for medium-voltage rectification tasks within these specialized markets.

Replacement Considerations

Substitute parts must match the 600 V reverse voltage, 1 A forward current, and axial package type. Verify that alternative manufacturers offer equivalent MIL-PRF-19500/286 qualification if military grade is required. Ensure the replacement maintains the same hermetic sealing and voidless glass construction standards.
