TLP781F(D4-GRL,E)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP781F(D4-GRL,E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Arsenide infrared emitting diode with a silicon phototransistor, housed in a 4-lead plastic DIP package with a 10.16mm pitch. The device provides high isolation voltage of 5000Vrms minimum. Key electrical parameters include a collector-emitter breakdown voltage of 80V minimum, a forward voltage of 1.3V typical, and a current transfer ratio of 100% minimum for the GB rank. Operating temperatures range from -25°C to 85°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High isolation voltage capability of 5000Vrms minimum between input and output circuits.
• Optical coupling via GaAs IRED and silicon phototransistor ensures signal transmission across different voltage levels.
• DIP4 package design with 10.16mm pitch facilitates through-hole mounting on printed circuit boards.

Transistor, Photovoltaic Output Optoisolators Applications

• Office equipment control systems
• Household appliance interfaces
• Solid state relay switching drivers
• Signal transmission between isolated voltage domains

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix GRL corresponds to the required CTR rank and packaging configuration. Confirm compliance with RoHS directives and check for UL, CSA, or VDE certifications if safety isolation is mandated. Ensure the 10.16mm DIP footprint matches the target PCB layout requirements before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and moderate speed are required for DC signal transmission. The GB rank ensures a minimum CTR of 100%, suitable for reliable switching applications. Consider the 85°C maximum operating temperature limit for thermal management in enclosed environments compared to higher temperature variants.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP781 series, which features a standard DIP4 form factor. The 'F' designation typically indicates the wider 10.16mm pitch variant, distinguishing it from the narrower 7.62mm pitch TLP781. The GRL suffix specifies the current transfer ratio ranking and lead plating type within the Toshiba product line.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

TLP781(D4-GB-LF7) offers identical electrical characteristics and pinout but utilizes a 7.62mm pitch DIP4 package. Verify mechanical clearance and hole spacing compatibility before substituting, as the physical dimensions differ significantly despite functional equivalence.
