Overview
The Microchip Technology 1N645-1 is a standard recovery rectifier diode designed for high-reliability applications. It features a maximum DC reverse voltage of 225 V and an average rectified current of 400 mA. The device utilizes a surface-mount DO-213AA package and operates within a junction temperature range of -65°C to 175°C. It exhibits a forward voltage of 1 V at 400 mA and a reverse leakage current of 50 nA at 225 V. Qualified under MIL-PRF-19500/240, it is available in JAN, JANTX, and JANTXV levels.
Feature Summary
- Military qualification per MIL-PRF-19500/240 standards
- Surface-mount DO-213AA package construction
- Extended operating temperature range up to 175°C
Applications
- High-reliability military electronic systems
- Computer signal rectification circuits
- Harsh environment power management
Procurement Notes
Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application when ordering. Confirm that the DO-213AA surface-mount footprint matches your PCB design. Ensure compliance with RoHS status requirements as indicated by the manufacturer's documentation for this specific part number.
Selection Notes
Select this component when a small surface-mount form factor is required alongside military-grade reliability. The 400 mA current rating suits low-power signal or computer diode applications. Consider the 225 V reverse voltage limit to ensure adequate headroom for the circuit's peak inverse voltage requirements.
Part Context
This diode belongs to the 1N645 series, which includes various qualification levels. It serves as the surface-mount equivalent to axial leaded variants. The product line is managed by Microchip Technology, formerly Microsemi, focusing on specialized semiconductor solutions for demanding industries.
Replacement Considerations
Direct substitutes include other 1N645 series parts such as 1N645UR-1. Verify that any replacement maintains the same MIL-PRF-19500/240 qualification level and DO-213AA package dimensions to ensure mechanical and electrical compatibility.
