1N3274

Single Diodes Overview

The Microchip Technology 1N3274 is a standard rectifier diode housed in the DO-205AB (DO-9) stud mount package. It features a glass-to-metal seal construction and a glass passivated die. The device is rated for a maximum repetitive peak reverse voltage of 1200V and an average rectified forward current of 275A. It exhibits high surge current capability with a non-repetitive peak forward current rating of 5000A. The component utilizes soft recovery characteristics and is designed for high-current applications.

Single Diodes Procurement Notes

Verify the manufacturer source carefully, as multiple vendors list this part. Confirm the specific lot date code and condition, as some listings indicate used or obsolete stock. Ensure the package matches the DO-205AB specification. Check for RoHS compliance status if required by your assembly process. Cross-reference the electrical ratings against your circuit requirements before finalizing the order.

Single Diodes Selection Notes

Select this component when a robust standard rectifier with high surge tolerance is required. The 1200V reverse voltage rating suits medium-to-high voltage AC-DC conversion. The 275A average current capacity supports heavy-duty loads. Consider the stud mount form factor for direct heatsinking. Verify that the soft recovery trait aligns with your switching frequency and EMI constraints.

Single Diodes Part Context

This diode belongs to the standard rectifier family from Microchip Technology. It shares the DO-9 stud package style with similar high-power devices. The 1N3274 designation follows the JEDEC numbering system for silicon rectifiers. It is distinct from fast recovery or Schottky variants due to its standard recovery profile and high current handling.

Single Diodes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify compatibility with equivalent 1200V, 275A stud-mount rectifiers from other manufacturers based on pinout and thermal specifications.
