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, 3 shorted together and pins 4, 6 shorted together.




Description

The TLP127 is designed as a small outline coupler, suitable for surface mount assembly. It consists of a gallium arsenide infrared emitting diode, optically coupled to a darlington photo transistor with an integral base-emitter resistor, and provides 300V Vceo.

TLP127 has four features. (1) Its collector to emitter voltage is min 300V. (2) Its current transfer ratio is 1000% min. (3) Its isolation voltage is 2500Vrms min. (4) Its UL recodnized is UL 1577, file No.E67349. That are all the main features.

Some absolute maximum ratings of TLP127 have been concluded into several points as follow. (1) For the LED its forward current would be 50mA. (2) Its forward current derating would be -0.7mA/°C. (3) Its pulse-forward current os 1A. (4) Its reverse voltage is 5V. (5) Its junction temperature is 125°C. (6) For the detector its collector to emitter voltage is 300V. (7) Its emitter to collector voltage is 0.3V. (8) Its collector current is 150mA. (9) Its collector power dissipation is 150mW. (10) Its collector power dissipation derating is -1.5mW/°C. (11) Its operating temperature range is from -55°C to 100°C. (12) Its storage temperature range is from -55°C to 125°C. (13) Its lead soldering temperature is 260°C (10s). (14) Its total package power dissipation is 200mW. (15) Its total package power dissipation derating is -2.0mW/°C. (16) Its isolation voltage is 2500(AC, 1min, RH<=60%.) Vrms.

Also some electrical characteristics about TLP127. (1) For the LED its forward voltage is min 1.0V and typ 1.15V and max 1.3V. (2) Its capacitance is typ 30pF. (3) Its reverse current is max 10uA. (4) For the detector its collector to emitter breakdown voltage is min 300V. (5) Its emitter to collector breakdown voltage is min 0.3V. (6) Its collector dark current is typ 10nA and max 200nA and it would be max 20uA at Ta=85°C. And so on.
