TLP557
TOSHIBA Photocoupler IRED & Photo-IC
Industrial Inverter Inverter for Air Conditioner Power Transistor Base Drive
The TOSHIBA TLP557 consists of an infrared emitting diode and an integrated photodetector. This unit is 8-lead DIP package. TLP557 is suitable for base driving circuit of power transistor module up to 20A. External resistor needs to connect between pin 6 and pin 7. This is for constant current driving.
