Photocoupler - Toshiba Semiconductor
Description
TOSHIBA Photocoupler IRED & Photo-IC
Industrial Inverter Inverter for Air Conditioner Power Transistor Base Drive
TLP557
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.
