Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix GRH-T7,F against official Toshiba documentation to confirm the exact reel quantity and tape specifications. Ensure the ordering code matches the required surface-mount package variant. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel isolation solution with high voltage withstand capability is required. The NPN phototransistor output is suitable for standard logic interfacing. Consider the 80 V collector-emitter voltage rating for higher voltage load driving compared to lower-rated alternatives. Verify that the surface-mount DIP-4 footprint aligns with the target PCB design constraints and assembly capabilities.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the TLP785 series of transistor output optocouplers from Toshiba. The series is designed for general-purpose digital isolation tasks. Variants within the series differ primarily by packaging type, such as through-hole DIP or surface-mount configurations, and specific shipping formats like tubes or reels. The TLP785F designation indicates the base product family with standardized electrical parameters.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include other single-channel transistor output optocouplers with similar 5000 Vrms isolation ratings and NPN outputs. Verify pinout compatibility and physical dimensions when replacing. Check if alternative parts meet the same 80 V collector-emitter voltage and 10 mA collector current requirements to ensure circuit functionality remains unchanged.
