# DL4007

**MDD Microdiode Semiconductor** · Diodes - General Purpose · DO-213AB

DL4007 from MDD Microdiode Semiconductor, in a DO-213AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal, the solderable end on the side of the body with the polarity band marking; the part is rated for 50 to 1000 V reverse voltage depending on type, with DL4007 at 1000 V VRRM. |
| 2 | A | passive | Anode terminal, the solderable end opposite the polarity band; rated for 1.0 A average forward rectified current and 30 A peak surge current. |
