What the TLP109 family does
The TLP109 is a mini-flat optocoupler combining a high-output infrared LED with a high-speed photodiode-transistor chip. Housed in an SO6 package, it features a 3750 Vrms isolation voltage and 0.8 μs maximum switching speed. The component supports a 30 V supply voltage and 8 mA output current. It is designed for surface-mount assembly in applications requiring reinforced insulation, such as programmable controllers, industrial inverters, and switching power supplies.
