Home / Functions of each pin of the laser diode
The LDC (Laser Diode Cathode) and PDA (Photodiode Anode) terminals are connected to the negative side, ensuring that the laser diode is forward biased and the photodiode is reverse biased. To maintain stable light output, a transistor-based current driver circuit is used. ROHM refers to the pins of a three-pin package as pins 1, 2 and 3, clockwise when viewed from the top of the package (the side where the laser beam is emitted). Application is going to define the major parameters of a laser diode: wavelength, power, and package style. A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. A laser diode consists of the p-n junction where both electrons and holes are involved.
