TPSMBJ20A from TECH PUBLIC, 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 | K | passive | Cathode of the unidirectional TVS, marked by the cathode band on the SMB (DO-214AA) body; TPSMBJ20A has VR 20 V, VBR 22.20-24.50 V at 1 mA and VC 32.4 V max at IPP 18.6 A. |
| 2 | A | passive | Anode of the unidirectional TVS on the SMB (DO-214AA) package, the terminal opposite the cathode band; peak pulse power is min 600 W on 10/1000 us waveform. |
