1N1204A

Single Diodes Overview

The Microchip Technology 1N1204A is a silicon rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 12 A and a peak repetitive reverse voltage rating of 400 V. The device utilizes a DO-4 (DO-203AA) metal package with a cathode-connected case, supporting junction temperatures up to 150 °C.

Single Diodes Feature Summary

• Constructed from silicon material for robust rectification performance

• Designed for through-hole mounting via stud installation style

Single Diodes Applications

• General purpose rectification circuits
• Power supply input stages
• Industrial equipment power management

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as International Rectifier (Infineon) also produces this part number. Confirm RoHS compliance status, as documentation indicates non-compliance for certain variants. Ensure the DO-4 package dimensions match the target PCB or chassis mounting requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring high surge current handling capabilities alongside standard recovery speeds. The metal case construction facilitates effective heat dissipation for continuous 12 A operation. Verify that the 400 V reverse voltage rating exceeds the peak inverse voltage present in the circuit design to ensure reliable long-term operation under thermal stress.

Single Diodes Part Context

This component belongs to the broader category of discrete semiconductor diodes manufactured by Microchip Technology and its acquired entities. It serves as a fundamental passive-active hybrid element in power electronics, distinct from integrated logic or memory devices. The 1N1204 series represents a legacy standard form factor adapted for modern industrial reliability standards.

Single Diodes Replacement Considerations

Direct substitutes include other 12 A, 400 V silicon rectifiers in the DO-4 package. Verify pinout compatibility, specifically the cathode-connected case configuration, when replacing with equivalent parts from different manufacturers.
