SM6T220A-E3
Vishay Intertech · TVS · DO-214AA(SMBJ)
SM6T220A-E3 from Vishay Intertech, in a DO-214AA(SMBJ). 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 cathode band; the device is unidirectional with VWM 188 V and VBR 209 V to 231 V for SM6T220A. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, at the end opposite the cathode band; clamps at max 328 V at 2.00 A (10/1000 μs). |
