TECH PUBLIC · MOSFETs · SOD-523

TPB1A40-523-1 from TECH PUBLIC, in a SOD-523. 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 terminal marked by the dark band and the "−" sign on the outline drawing; the diode's DC reverse voltage is rated 40 V maximum and mean rectifying current is 1 A.
2 A passive Anode, the terminal marked "+" on the outline drawing; the diode's non-repetitive peak forward surge current is 7 A (t=8.3 ms) and the junction temperature range is -40 to +125 °C.
