Overview
The 1N645-1/TR is a silicon rectifier diode manufactured by Microchip Technology. It features a metallurgically bonded, hermetically sealed double plug construction housed in the DO-213AA surface mount package. The component is rated for 225 V reverse voltage and 400 mA forward current. It complies with MIL-PRF-19500/240 specifications, available in JAN, JANTX, and JANTXV grades.
Feature Summary
- Hermetically sealed double plug construction
- Metallurgically bonded silicon rectifier
- Compliance with MIL-PRF-19500/240 standards
Applications
- General purpose rectification in power supplies
- Clipping applications
- Steering applications
Procurement Notes
Verify the specific grade (JAN, JANTX, or JANTXV) required for your application, as performance varies by qualification level. Confirm that the DO-213AA package matches your PCB footprint. Ensure the supplier provides documentation confirming compliance with MIL-PRF-19500/240 if military-grade reliability is mandated. Check for RoHS status if environmental regulations apply to your deployment.
Selection Notes
Select this component when a hermetically sealed, high-reliability silicon rectifier is needed for surface mount assembly. The 225 V rating suits low-voltage DC circuits requiring isolation or rectification. Consider the 400 mA current limit for load requirements. This part serves as a robust alternative to standard small-signal diodes in demanding environments where leakage and breakdown stability are critical.
Part Context
This device belongs to the 1N645 series of silicon switching diodes produced by Microchip Technology. It is designed for general-purpose rectification tasks. The series includes through-hole variants like the 1N645-1 in DO-204AH packages. The -1 suffix typically denotes specific electrical characteristics within the family, while /TR indicates tape and reel packaging for automated assembly.
Replacement Considerations
Direct substitutes include other MIL-PRF-19500/240 compliant diodes such as the 1N645-1 from Microsemi. Verify pinout compatibility between DO-213AA and potential replacements. Ensure thermal and electrical ratings meet or exceed the original specifications. Cross-reference with equivalent commercial parts only if hermetic sealing is not required.
