Product Summary

The SFH6943-4 is a four channel mini-optocoupler suitable for high density packaged PCB application. The SFH6943-4 has a minimum of 1768 VRMS isolation from input to output. The device consists of four phototransistors as detectors. Each channel is individually controlled. The optocoupler is housed in a SOT223/10 package. All the cathodes of the input LEDs and all the collectors of the output transistors are common enabling a pin count reduction from 16 pins to 10 pins-a significant space savings as compared to four channels that are electrically isolated individually. Application areas of the SFH6943-4 include Telecommunication, SMT, PCMCIA, Instrumentation.
