FUXINSEMI · Fast Recovery / High Efficiency Diodes · SMA(DO-214AC)
STTH112A-FS from FUXINSEMI, in a SMA(DO-214AC). 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 end marked with the colour band; the datasheet rates reverse voltage up to 1200 V (VRRM). |
| 2 | A | passive | Anode terminal; rated for 1 A average forward current (IF(AV) at Tl = 115°C) and 50 A forward surge (8.3 ms). |
