SDT470 DC Input 80V Photo-Transistor Optocoupler Description Features The SDT470 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 SDT470 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry. The SDT470 comes standard in an ultra miniature 4 pin SSOP package. Agency Approvals UL: C-UL: VDE: Applications Ultra miniature 4 pin SSOP package Low input power consumption High stability CTR Range 80 – 600% High Isolation Voltage (3750VRMS) Long Life / High Reliability RoHS / Pb-Free / REACH Compliant Office Automation Equipment System Appliances, Measuring Instruments Computer Terminals, PLCs Telecom / Datacom Home Appliances Digital Logic Inputs Fax / Modems Power Supplies Absolute Maximum Ratings The values indicated are absolute stress ratings. Functional operation of the device is not implied at these or any conditions in excess of those defined in electrical characteristics section of this document. Exposure to absolute Maximum Ratings may cause permanent damage to the device and may adversely affect reliability.
