WEOS61089-17F from Wayon, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K1 | passive | Cathode 1 (Tip). Line-side terminal of thyristor/diode pair 1 protecting the Tip conductor. |
| 2 | G | input | Gate terminal. Referenced to -VBAT to program the negative firing voltage of both thyristors. IGT = 5 mA max, VGT = 2.5 V max. |
| 3 | NC | unconnected | No connect. Leave floating or tie to a non-critical net. |
| 4 | K2 | passive | Cathode 2 (Ring). Line-side terminal of thyristor/diode pair 2 protecting the Ring conductor. |
| 5 | K2 | passive | Cathode 2 (Ring). Second bond to the Ring-side cathode; internally common with pin 4 to reduce parasitic inductance for fast transients. |
| 6 | A | passive | Anode (Ground). Common anode of both protection thyristors and clamp diodes; tie to system ground. |
| 7 | A | passive | Anode (Ground). Second ground bond; internally common with pin 6 to reduce Ldi/dt drop during a surge. |
| 8 | K1 | passive | Cathode 1 (Tip). Second bond to the Tip-side cathode; internally common with pin 1 to reduce parasitic inductance for fast transients. |
