ZLLS350TA

Diodes Incorporated · Schottky Barrier Diodes (SBD) · SOD-523

ZLLS350TA from Diodes Incorporated, 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, marked by the cathode band on the SOD523 package; the diode is rated for 40V DC blocking voltage and 380mA continuous forward current.
2 A passive Anode terminal of the Schottky diode in the SOD523 package, with forward voltage of 395mV typical at IF = 30mA.
