# FR207

**MDD Microdiode Semiconductor** · Fast Recovery / High Efficiency Diodes · DO-15

FR207 from MDD Microdiode Semiconductor, in a DO-15. 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 lead, the end marked by the polarity band on the body; rated for 50 to 1000 V repetitive peak reverse voltage (1000 V for FR207) and 2.0 A average forward current. |
| 2 | A | passive | Anode lead at the end opposite the polarity band; carries up to 2.0 A average forward rectified current at TA=75°C with VF of 1.30 V max at 2.0 A. |
