SSA24

onsemi · Schottky Barrier Diodes (SBD) · SMA(DO-214AC)

SSA24 from onsemi, in a SMA(DO-214AC). 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 Cathode passive Cathode terminal, marked by the color band on the SMA/DO-214AC package; SSA24 is rated for 40 V VRRM/VDC and 2 A average forward current.
2 Anode passive Anode terminal of the Schottky rectifier, opposite the color-band end of the SMA/DO-214AC package.
