P0300SA from SEMIWARE, in a DO-214AA(SMB). 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 | 1 | passive | Terminal 1 of the bidirectional thyristor surge suppressor; P0300SA has VDRM 25 V min, VS 40 V max (at 100 kV/s) and IPP 150 A (2x10 µs) across the two terminals. |
| 2 | 2 | passive | Terminal 2 of the bidirectional thyristor surge suppressor; P0300SA has IH 40 mA min, IT 4 A at VT 2.2 V max, and 70 pF typ off-state capacitance across the two terminals. |
