SFH6941

EW SFH6941 LOW CURRENT INPUT MINI OPTOCOUPLER Preliminary Data Sheet FEATURES • Transistor Optocoupler in SOT223 Package • End Stackable, 1.27 mm Spacing • Low Current Input • Very High CTR, 150% Typical at IF=1 mA, VCE=0.5V • 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: 2500 VDC APPLICATIONS • Telecommunication • SMT • PCMCIA • Instrumentation DESCRIPTION The SFH6941 is a four channel mini-optocoupler suitable for high density packaged PCB application. It has a minimum of 2500 VDC 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 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.
