1N1202A

Single Diodes Overview

The Microchip Technology 1N1202A is a silicon power rectifier diode designed for high-reliability applications. It features a 200V repetitive peak reverse voltage and a 12A average forward rectified current capability. The device utilizes a glass-passivated die with a glass-to-metal seal construction, ensuring robust performance in demanding environments. It is available in the DO-203AA (DO-4) stud mount package, suitable for screw-type installation. This component meets MIL-PRF-19500/260 specifications and is offered in JAN, JANTX, and JANTXV grades for military and aerospace use.

Single Diodes Procurement Notes

Verify the specific grade (JAN, JANTX, or JANTXV) required for your application, as these denote different quality levels and testing criteria per MIL-PRF-19500/260. Confirm that the DO-203AA package dimensions match your mechanical design constraints. Ensure the supplier provides traceability documentation consistent with military procurement standards. Check for any specific handling instructions related to the glass-to-metal seal construction during assembly.

Single Diodes Selection Notes

Select the 1N1202A when a 200V reverse voltage rating and 12A forward current capacity are necessary within a stud-mount form factor. Consider this component for designs requiring compliance with MIL-PRF-19500/260 standards. Evaluate the thermal requirements of the application to ensure adequate heat sinking for the DO-203AA package. Compare alternative grades based on the required level of screening and reliability assurance for the specific mission profile.

Single Diodes Part Context

The 1N1202A belongs to Microchip's family of military-grade silicon power rectifiers. These components are engineered for durability in harsh environments, utilizing glass passivation to protect the junction. The DO-4 package is a traditional stud-mount style widely used in legacy and high-power military electronics. Availability spans multiple qualification levels to meet varying budget and reliability needs within defense and aerospace sectors.

Single Diodes Replacement Considerations

Direct substitutes must match the 200V, 12A, DO-203AA specification and hold equivalent military qualifications. Verify pinout compatibility and thermal resistance characteristics before substitution. Cross-reference with other manufacturers' MIL-PRF-19500/260 compliant parts if Microchip availability is constrained.
