TOSHIBA Photocoupler GaAℓAs Ired & Photo-IC
Industrial Inverter
Inverter for Air Conditioner
Power Transistor Base Drive
TLP557
Unit: mm
The TOSHIBA TLP557 consists of a GaAℓAs light 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.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if
the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 1: Device considered a two terminal device: Pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted
together.
