P6SMB120A
Littelfuse · TVS · DO-214AA(SMBJ)
P6SMB120A from Littelfuse, 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 color band on the package; for P6SMB120A the reverse stand-off voltage is 102 V and breakdown voltage is 114 V min to 126 V max at 1 mA. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band; the maximum clamping voltage is 165 V at 3.7 A peak pulse current and forward voltage is below 3.5 V at 50 A. |
