SFH6943

SFH6943 Low Current Input Mini Optocoupler FEATURES Transistor Optocoupler in SOT223/10 Package End Stackable, 1.27 mm Spacing Low Current Input Very High CTR, 150% Typical at IF=1 mA, VCE=5 V Good CTR Linearity Versus Forward Current Minor CTR Degradation Field Effect Stable by TRIOS (TRansparent IOn Shield) High Collector-Emitter Voltage, VCEO=70 V Low Coupling Capacitance High Common Mode Transient Immunity Isolation Test Voltage: 1768 VRMS APPLICATIONS Telecommunication SMT PCMCIA Instrumentation DESCRIPTION The SFH6943 is a four channel mini-optocoupler suitable for high density packaged PCB application. It 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 commoned 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.
