1N1202R

Single Diodes Overview

The 1N1202R is a single silicon power rectifier diode manufactured by Microchip Technology. It features a maximum average forward current of 12A and a peak repetitive reverse voltage rating of 200V. The component utilizes a DO-4 (DO-203AA) glass-to-metal sealed package, designed for robust performance in high-reliability applications.

Single Diodes Feature Summary

• High-current capability with 12A average forward rectification
• Standard recovery characteristics for general-purpose rectification
• Glass-to-metal sealed construction for environmental durability

Single Diodes Applications

• Military power supply circuits
• Industrial rectifier bridges
• High-reliability DC power conversion systems

Single Diodes Procurement Notes

Verify the manufacturer origin, as Microsemi was acquired by Microchip Technology. Confirm the specific suffix indicates the standard military-grade variant. Ensure the DO-4 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 200V reverse voltage rating and 12A continuous current are required. The DO-4 package offers superior thermal dissipation compared to smaller plastic packages. Consider the glass-to-metal seal for harsh environment resistance where plastic encapsulation may fail.

Single Diodes Part Context

This part belongs to the 1N series of standard silicon rectifiers. It shares the same electrical ratings as the non-suffixed 1N1202 but typically denotes a specific military or high-reliability qualification level under the Microchip/Microsemi product line.

Single Diodes Replacement Considerations

The 1N1202 is the base equivalent part number. Verify if the 'R' suffix implies specific testing or packaging differences that affect interchangeability in critical military applications.
