Key Parameters

Substitute Part Grouping Explanation

The TLP785(D4-BL,F) has one parametric equivalent substitute: TLP785(BL,F). Both parts share identical electrical specifications and mechanical characteristics that define substitutability for optoisolator applications. The key parameters determining substitution eligibility are:

• Voltage isolation rating: 5000Vrms
• Number of channels: 1
• Current transfer ratio range: 200% to 600% @ 5mA
• Output type: Transistor
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Operating temperature range: -55°C ~ 110°C
• Package configuration: 4-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

The difference between these part numbers lies in packaging format (tube versus tape and reel), not in electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both TLP785(D4-BL,F) and TLP785(BL,F) are active production parts from Toshiba Semiconductor and Storage with identical electrical and mechanical specifications.
