TLP557 TOSHIBA Photocoupler IRED & Photo-IC TLP557 Industrial Inverter Inverter for Air Conditioner Power Transistor Base Drive Unit: mm 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. Input threshold current: IF = 5 mA (max) Guaranteed performance temperature range: -30 to 70C Supply voltage: 16 V (max) Output current: 0.3 A (max) TOSHIBA 11-10C4S Switching time (tpLH/tpHL): 5 s (max) Weight: 0.54 g (typ.) Isolation voltage: 2500 Vrms (min) UL-recognized: UL 1577, File No.E67349 cUL-recognized: CSA Component Acceptance Service No.5A File No.E67349 Pin Configuration (top view) 1 8 Schematic I CC 2 7 V CC (T ) r1 8 I F 3 6 7 V O1 2 + (Rex) V F 4 5 6 3 V O2 I O 1 : N.C.

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. 2019 2 2019-06-24 Toshiba Electronic Devices & Storage Corporation Detector LED
