Additional Details

The TLP850 typically comes in a DIP (Dual In-line Package) or SMD (Surface Mount Device) package. It operates with a forward current on the input side to activate the LED, which in turn triggers the photodetector on the output side. It boasts a high common-mode transient immunity, crucial for noisy industrial environments.
