Single Diodes Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure the component meets regional availability requirements as this product line is designated for markets outside Japan. Cross-reference datasheet revision dates to validate parameter consistency before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for applications requiring fast reverse recovery characteristics and robust thermal performance. The wide operating temperature range supports demanding environments. Verify that the 100V reverse voltage rating aligns with circuit peak inverse voltage requirements. Confirm physical dimensions match the DO-35 or equivalent leaded package constraints of the target assembly.

Single Diodes Part Context

This part belongs to the standard switching diode family produced by ROHM Semiconductor. It shares core electrical characteristics with related models such as the 1N4148, 1N4531, 1N4150, and 1N4448. The primary distinction lies in the specific ordering suffix which dictates packaging details rather than altering fundamental semiconductor properties.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4148, 1N4531, 1N4150, and 1N4448 from the same manufacturer series. These alternatives share identical electrical ratings and functional profiles. Verify package compatibility when substituting.
