Activity and products sub-mount product, zener diode, photo diode, APD, avalanche photo diode, panel control IC for home application, submount, P&LSEM stands for "Power and Liting Semiconductor", a company that specializes in manufacturing and selling optical power semiconductors using light. Since its founding in 2015, P&LSEM is a sub-mount product necessary for heat dissipation and reflection-refraction characteristics of various optical semiconductor products, ESD and overvoltage. By developing and producing zener diodes for device protection and photodiodes that detect the intensity of light, we achieved sales of 3.4 billion won in 2019, growing more than 20% annually, and 50% of these are exported overseas, contributing to national competition. Based on this, we are striving to develop new products, launching “Avalanch Photo Diode” and “Panel Control IC for Home Appliances”, and are striving to export overseas.
