TLP785(BLL,F

Transistor, Photovoltaic Output Optoisolators Overview

The TLP785(BLL,F is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with a silicon phototransistor within a four-lead plastic DIP package. The device provides a minimum isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical specifications include a maximum collector-emitter voltage of 80 V, a forward current rating of 60 mA, and a typical forward voltage of 1.15 V. The unit features fast switching characteristics with a typical rise time of 2 µs and fall time of 3 µs. It supports a wide operating temperature range from -55°C to +110°C and complies with RoHS standards.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BLL' against official Toshiba documentation to confirm the exact Current Transfer Ratio (CTR) binning or lead configuration, as suffixes often denote specific performance grades or packaging variations. Ensure the ordering part number matches the required CTR range and physical package dimensions for your PCB layout. Cross-reference with authorized distributors to confirm current production status and availability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside high voltage withstand capabilities. The 80 V collector-emitter voltage rating suits low-voltage logic interfacing, while the 5000 Vrms isolation protects control circuitry from high-voltage transients. Consider the DIP-4 package for through-hole mounting or verify if surface-mount variants like the GR series are needed for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Part Context

The TLP785 belongs to Toshiba's general-purpose transistor output optocoupler family, designed for industrial and consumer applications. It serves as a standard solution for galvanic isolation in data communication and power control systems. The series is recognized for its reliability and compliance with international safety standards, including UL, VDE, and CQC certifications, facilitating global product deployment.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba TLP785 variants with different CTR rankings or packages, such as TLP785(GB,F or TLP785(GR-TP6,F. Verify pin compatibility and isolation voltage ratings before substitution. Generic replacements must match the 5000 Vrms isolation and 80 V Vceo specifications.
