The OR-6N137S-TA1 is an optocoupler manufactured by Orient and comes in a Surface Mounted Device (SMD) package with 8 pins in the RoHS compliant variant. This optocoupler can be used for electrical isolation between two circuits. It has a control element optical output (channel light emitting diode (LED) and output interface photodetector transistor integrated circuit (IC) detector input), with an insulation voltage of 5000Vrms. It has a maximum operating temperature range between -40°C to +100°C and fast response time of 8µs on-100µs off (high speed type), usually used in AC or DC control application with PLCs, power supplies, and automotive electronics. The OR-6N137S-TA1 provides high EMI protection and is compatible with most industrial standards.
