KSMF26CA-E3-08
KUU · ESD And Surge Protection (TVS/ESD) · SOD-123FL
KSMF26CA-E3-08 from KUU, in a SOD-123FL. 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 | Cathode | passive | Cathode terminal of the SOD-123FL package, identified as pin 1 in the datasheet pinning table and top view. The datasheet gives no electrical limits for this pin alone; the rated values apply to the device as a whole (PPPM 200 W, VRWM 5.0 V to 220 V, TJ/TSTG -55 to +150 °C). |
| 2 | Anode | passive | Anode terminal of the SOD-123FL package, identified as pin 2 in the datasheet pinning table and top view. The datasheet gives no electrical limits for this pin alone; the rated values apply to the device as a whole (PPPM 200 W, VRWM 5.0 V to 220 V, TJ/TSTG -55 to +150 °C). |
