SFH620A-3 Optocoupler, phototransistor output, 5.3 KV, CTR 100-320%, DIP-4

Optocoupler, Phototransistor Output, AC Input

Description The SFH620A (DIP) and SFH6206 (SMD) feature a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 or SMD package. The coupling devices are designed for signal transmission between two electrically separated circuits. The couplers are end-stackable with 2.54 mm lead spacing. Creepage and clearance distances of > 8 mm are achieved with option 6. This version complies with IEC 60950 (DIN VDE 0805) for reinforced insulation to an operation voltage of 400 VRMS or DC.

Features - 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 - Low CTR degradation - Temperature stable - Low coupling capacitance - End-stackable, 0.100" (2.54 mm) spacing - High common-mode interference immunity
