The HSMF-A206-A00J1 is a discrete LED light emitting diode (LED) indication from Broadcom. It has two LED indications, one green LED with a wavelength of 569 nm, and one yellow LED with a wavelength of 585 nm, both with a voltage of 2.2V. The device is 4-PLCC, which is a four-pin leadless ceramic package, and is available in green and yellow, depending on the application and desired color. This LED indication is commonly used for status, warning or critical indication such as on/off or error lights, or in combination with other LEDs to form a discrete indication.
