DESCRIPTION

• Component in accordance to RoHS 2002/95/EC and

WEEE 2002/96/EC

The SFH6943A is a four channel mini-optocoupler suitable

for high density packaged PCB application. It has a minimum

of 1768 V_RMSisolation 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.

APPLICATIONS

• Telecommunication

• SMT

• PCMCIA

• Instrumentation

AGENCY APPROVALS

• UL1577, file no. E52744 system code V

• CSA 93751
