SMP75-8 from STMicroelectronics, 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 | A1 | passive | Bidirectional crowbar protection terminal 1 (top terminal in Figure 1), interchangeable with terminal 2, with 8 V voltage rating, IR = 2 µA max leakage and IH = 150 mA min holding current. |
| 2 | A2 | passive | Bidirectional crowbar protection terminal 2 (bottom terminal in Figure 1), interchangeable with terminal 1, with repetitive peak pulse current IPP = 75 A (10/1000 µs). |
