Littelfuse · TVS · DO-204AC(DO-15)
SA30CA from Littelfuse, in a DO-204AC(DO-15). 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 | Bidirectional terminal 1 (axial lead, no cathode band on CA parts); SA30CA has VR 30.0V, VBR 33.30-36.80V at 1mA, and VC max 48.4V at 10.5A Ipp. |
| 2 | A2 | passive | Bidirectional terminal 2 (axial lead, interchangeable with the other terminal since the cathode band applies to unidirectional parts only); max leakage 1µA at VR 30.0V. |
