1N1204AR

Single Diodes Overview

The Microchip Technology 1N1204AR is a silicon rectifier diode designed for general-purpose applications. It features a maximum average forward current of 12 A and a peak repetitive reverse voltage rating of 400 V. The device utilizes a DO-203AA (DO-4) metal package with a cathode-connected case, suitable for through-hole mounting. It operates at a maximum junction temperature of 150 °C and supports a non-repetitive peak forward surge current of 240 A.

Single Diodes Feature Summary

• High thermal stability with a maximum operating junction temperature of 150 °C
• Robust mechanical construction using a metal DO-203AA (DO-4) package
• Case connected to the cathode terminal for efficient heat dissipation

Single Diodes Applications

• General-purpose rectification in power supplies
• Industrial equipment power stages
• Consumer electronics AC-to-DC conversion

Single Diodes Procurement Notes

Verify the specific manufacturer source, as this component is produced by multiple vendors including International Rectifier and Microsemi. Confirm that the ordering suffix 'AR' corresponds to the required packaging configuration and material compliance status. Ensure the datasheet matches the exact electrical ratings for your design requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a standard recovery silicon rectifier with a 12 A continuous current rating is required. The 400 V reverse voltage rating makes it suitable for low-voltage AC mains applications. Consider the metal package size and through-hole mounting style for compatibility with existing PCB layouts and thermal management strategies.
