SFH615A-4 DC Input Phototransistor Output Optocoupler Through Hole 4-Pin DIP

The SFH615A features a variety of transfer ratios, 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 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 up to an operating voltage of 400 V RMS or DC. Specifications are subject to change.

• Excellent CTR linearity depending on forward current.
• Isolation test voltage, 5300 V RMS.
• Fast switching times.
• Low CTR degradation.
• Low coupling capacitance.
• Material categorization.
