• Voltage - Isolation: 5000Vrms rating
• Current Transfer Ratio: 50% (Min) @ 5mA and 400% (Max) @ 5mA
• Rise / Fall Time: 4µs and 5µs typical values
• Input Type: DC input
• Output Type: Transistor output
• Voltage - Output (Max): 80V maximum
• Current - Output / Channel: 50mA per channel
• Voltage - Forward (Vf): 1.1V typical
• Current - DC Forward (If) (Max): 60mA maximum
• Vce Saturation (Max): 300mV maximum
• Operating Temperature Range: -40°C to 115°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: 4-LSOP (2.54mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitutes maintain identical electrical performance and mechanical compatibility with the original PS2381-1Y-F3-AX specification.

Parameter Comparison

Engineering Selection Recommendations
