TPSMB24CA
Littelfuse · TVS · DO-214AA
TPSMB24CA from Littelfuse, in a DO-214AA. 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 | Bi-directional TVS terminal with no polarity (TPSMB24CA: VR 20.5 V, VBR 22.8 V at 1 mA, max clamping 33.2 V at 18.4 A); either terminal connects to the protected line. |
| 2 | A2 | passive | Bi-directional TVS terminal with no polarity (TPSMB24CA: VR 20.5 V, VBR 22.8 V at 1 mA, max clamping 33.2 V at 18.4 A); either terminal connects to the protected line or ground. |
