SF39 from EIC Semicon, in a DO-201AD. 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, the lead at the colour-band end of the molded body; SF39 has VRRM and VDC of 1000 V and IF(AV) of 3.0 A at Ta = 55 °C. |
| 2 | A | passive | Anode, the lead opposite the colour band; forward current up to 3.0 A average and IFSM of 65 A (8.3 ms half sine), with VF of 4.0 V maximum at IF = 3.0 A for SF38-SF39. |
