Optocoupler, Phototransistor Output,
SOT-223/10, Quad Channel
SFH6943A
Vishay Semiconductors
DESCRIPTION
The SFH6943A 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
SOT-223/10 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.
FEATURES
• Transistor optocoupler in SOT-223/10 package
• End stackable, 1.27 mm spacing
• Low current input
• Good CTR linearity versus forward current
• Minor CTR degradation
• High collector emitter voltage, VCEO = 70 V
• Low coupling capacitance
• High common mode transient immunity
• Isolation test voltage: 1768 VRMS
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
• Telecommunication
•SMT
•PCMCIA
• Instrumentation
AGENCY APPROVALS
• UL1577, file no. E52744 system code V
• CSA 93751
