PC817-4

The PC817-4 is one member of the PC817 series which is designed as high density mounting type photocoupler with typical applications of computer terminals; system appliances, measuring instruments; registers, copiers, automatic vending machines; electric home appliances, such as fan heaters, etc; and signal transmission between circuits of different potentials and impedances.

PC817-4 has four features. (1) Its current transfer ratio would be min 50% at If=5mA and Vce=5V. (2) It would have high isolation voltage between input and output which means Viso=5000Vrms. (3) It compacts dual-in-line package 40channel type. (4) It is recognized by UL, file No. E64380. That are all the main features.

Some absolute maximum ratings of PC817-4 have been concluded into several points as follow. (1) For input its forward current would be 50mA. (2) Its peak forward current would be 1A. (3) Its reverse voltage would be 6V. (4) Its power dissipation would be 70mW. (5) For output its collector to emitter voltage would be 35V. (6) Its emitter to collector voltage would be 6V. (7) Its collector current would be 50mA. (8) Its collector power dissipation would be 150mW. (9) Its total power dissipation would be 200mW. (10) Its isolation voltage would be 5000Vrms. (11) Its operating temperature would be from -30°C to +100°C. (12) Its storage temperature range would be from -55°C to +125°C. (13) Its soldering temperature would be 260°C.
