ElectronicsThe BPC-817MA with Optocouplers Through Hole RoHS is a surface-mount device manufactured by Bright LED Electronics. It is a four-pin, optically isolated package designed to protect sensitive electronic circuits from surges, spikes, and othervarious electrical abnormalities and interference. The optocoupler consists of a photodiode on the input side and an accompanying NPN transistor on the output side, and it operates in the 4kV isolation range. It features low power consumption, minimal crosstalk and noise, and high temperature and voltage performance. Its operating temperature range is -40°C to +85°C, and it can withstand up to 8kV ESD transient and surge protection. The BPC-817MA is an industry-standard component used to protect vital circuits from hazardous electrical contamination and extends product and system life.
