Overview
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...
