SFH620AA Overview
Description
The SFH620AA, SFH620AGB features a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 package.
Key Features
- High current transfer ratios
- at 5 mA: 50 to 600 %
- at 1.0 mA: 45 % typical (>
- Low CTR degradation
- Good CTR linearity depending on forward current
- Isolation test voltage, 5300 VRMS
- High collector emitter voltage, VCEO = 70 V
- Low saturation voltage
- Fast switching times
- Temperature stable
