SDT400

Single Channel Optocoupler, 60V, 50mA, CTR 50-600%, 5kV I/O Isolation, 4 pin DIP/SMD package

The SDT400 consists of a phototransistor optically coupled to a light emitting diode. Optical coupling between the input LED and output phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT400 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.

The SDT400 has 5 features.The first one is High input-to-output isolation package (5000 Vrms).The second one is Low input power consumption.The third one is High stability.The fourth one is Miniature 4 pin DIP package.The fifth one is CTR (CTR:MIN 50% at If=5mA Vce=5V).The SDT400 has 8 applications.The first one is Registers, copiers, Automatic Vending Machines.The second one is System appliances, measuring instruments.The third one is Computer terminals, PLCs.The fourth one is Telecommunications, telephones.The fifth one is Home Appliances.The sixth one is Digital logic inputs.The seventh one is Microprocessor inputs.The eighth one is Switching power supply, laser beam printers, etc.

The SDT400 has some maximum ratings.When parameter is storage temperature,the unit is ,the min is -55,the max is 125.When parameter is operating temperature,the unit is ,the min is -40,the max is 100.When parameter is input forward current,the unit is mA,the max is 50.When parameter is input peak forward current,the unit is A,the max is 1.When parameter is reverse input control voltage,the unit is V,the max is 6.When parameter is total power dissipation,the unit is mW,the max is 200.
