amsem · ESD And Surge Protection (TVS/ESD) · DO-214AB
8.0SMDJ33A from amsem, in a DO-214AB. 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 unidirectional TVS, marked by the color band on the body, which is the positive end; the datasheet gives VR 33 V, VBR 36.7-40.6 V at 1 mA, and VC 53.3 V at 150.1 A (10/1000μs). |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band, with 8000 W peak pulse power capability at 10/1000μs. |
