P3100SC-MS from MSKSEMI, in a 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 | T1 | passive | First terminal of the bidirectional thyristor surge protector (polarity-independent); P3100SC-MS has VS 350 V max at 100 kV/s, VD 275 V standoff, and 400 A 8/20us peak pulse current. |
| 2 | T2 | passive | Second terminal of the bidirectional thyristor surge protector (polarity-independent); P3100SC-MS has VT 4 V max at IT 2.2 A, IH 120 mA min, and 65 pF typical capacitance at 1 MHz. |
