• Voltage - Isolation: 5000Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Input Type: DC (exact match required)
• Output Type: Transistor (exact match required)
• Current Transfer Ratio range: 50% to 100% @ 1mA (exact match required)
• Voltage - Output (Max): 70V (exact match required)
• Current - Output / Channel: 50mA (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 8-SMD, Gull Wing (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

The FOD2743BSV meets all substitution criteria and is classified as an active product, providing supply continuity for the obsolete FOD2743CSV.
