LTST-C281TBKT-5A

Lite On · LED Indication - Discrete · 0402

LTST-C281TBKT-5A from Lite On, in a 0402. 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 (−) soldering terminal, identified by the green cathode mark on the package; reverse voltage is only applied for the IR test (VR = 5V) and the device is not designed for reverse operation.
2 A passive Anode (+) soldering terminal; the polarity symbol shows + on this side, with DC forward current limited to 20 mA (100 mA peak at 1/10 duty, 0.1 ms) and an external series resistor recommended.
