SDT400-R

SDT400-R DC Input 80V Photo-Transistor Optocoupler Description The SDT400-R consists of a phototransistor optically coupled to a light emitting diode. Optical coupling between the input IR LED and output phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT400-R provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry. The SDT400-R comes standard in a miniature 4 pin DIP package. Applications  Registers, Copiers, Automatic Vending Machines  System Appliances, Measuring Instruments  Computer Terminals, PLCs  Telecommunication Equipment, Telephones  Home Appliances  Digital Logic Inputs  Microprocessor Inputs  Switching Power Supplies Schematic Diagram Features  VCEO = 80V  Reversed Output (Emitter-Pin4, Collector-Pin3)  Low input power consumption  CTR Range 50 – 600% (Binning Available)  High Isolation Voltage (5000VRMS)  Long Life / High Reliability  RoHS / Pb-Free / REACH Compliant Agency Approvals UL/C-UL: VDE: File # E201932 File # 40035191 (EN 60747-5-2) Absolute Maximum Ratings The values indicated are absolute stress ratings.
