P6KE51CA
Littelfuse · TVS · DO-204AC(DO-15)
P6KE51CA 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 bipolar parts); P6KE51CA has VR 43.60 V, VBR 48.50 to 53.60 V at 1 mA, and max VC 70.1 V at Ipp 8.7 A. |
| 2 | A2 | passive | Bidirectional terminal 2 (axial lead, interchangeable with terminal 1); P6KE51CA has max reverse leakage 1 µA at VR 43.60 V and 600 W peak pulse power at 10/1000 µs. |
