P6KE520CA

DOWO · TVS · DO-15

P6KE520CA from DOWO, in a 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 First axial lead of the bidirectional TVS (P6KE520CA), no polarity; working peak reverse voltage 444.6 V, breakdown 494-546 V at 1 mA, max clamping 717.6 V at 0.84 A.
2 A2 passive Second axial lead of the bidirectional TVS (P6KE520CA), interchangeable with the first as there is no color band on bipolar parts; 600 W peak pulse power at 10/1000 µs.
