DESCRIPTION
The SFH640 has a GaAs infrared emitting diode emitter,
which is optically coupled to a silicon planar phototransistor
detector, and is incorporated in a plastic DIP-6 package.
It features a high current transfer ratio, low coupling
capacitance, and high isolation voltage.
The coupling device is designed for signal transmission
between two electrically separated circuits.

FEATURES
• Phototransistor optocoupler in a 6 pin DIP
package with base connection
• Very high collector emitter breakdown voltage,
BVCEO = 300 V
• Isolation rated voltage: 5000 VRMS
• Low coupling capacitance
