HSMW-C280

Broadcom Limited · LED Indication - Discrete · 0402

HSMW-C280 from Broadcom Limited, 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, on the end with the cathode mark and cathode line; reverse voltage is 5 V min at Ir=100 µA (a final-test condition, and long-term reverse bias is not recommended).
2 A passive Anode soldering terminal, on the end opposite the cathode mark; forward current is 20 mA max (100 mA peak at 1/10 duty, 0.1 ms) and forward voltage is 2.7 to 3.9 V at 20 mA.
