SAC5.0

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

SAC5.0 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 K passive Cathode, the end marked by the color band on this uni-directional TVS diode (SAC5.0: reverse standoff VR 5.0 V, breakdown 7.6 to 8.3 V, max clamping 13.2 V at 46.2 A).
2 A passive Anode, the axial lead opposite the cathode band of the uni-directional SAC5.0 TVS diode (500 W peak pulse power at 10/1000μs).
