SA15CA

amsem · Electrostatic And Surge Protection (TVS/ESD) · DO-204AC(DO-15)

SA15CA from amsem, 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 Bi-directional terminal (SA15CA): tin-plated axial lead with no polarity; the part clamps at VC 24.4 V max at IPP 20.5 A, VRWM 15 V, VBR 16.7-18.5 V at 1.0 mA.
2 A2 passive Bi-directional terminal (SA15CA): tin-plated axial lead with no polarity; either lead can be the more positive side, with 500 W peak pulse power (10/1000us) rating.
