15KPA48CA

amsem · ESD And Surge Protection (TVS/ESD) · P600

15KPA48CA from amsem, in a P600. 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 TVS terminal (axial lead) with no polarity marking; 48V reverse standoff, 53.6-58.9V breakdown at 5mA, 77.7V max clamping at 194.3A peak pulse current.
2 A2 passive Second bidirectional TVS terminal (axial lead), interchangeable with the other lead since the datasheet states the color cathode band is absent on bidirectional parts.
