DESCRIPTION

The SFH628A (DIP) and SFH6286 (SMD) feature a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared emitting diode, which is optically coupled to a silicon planar phototransistor detector, and isincorporated in a plastic DIP-4 or SMD package.

FEATURES

• High common mode interference immunity

• Isolation test voltage, 5300 VRMS

• Low coupling capacitance

• Good CTR linearity depending on forward current

• Low CTR degradation

• High collector emitter voltage, VCEO= 55 V
