TLP734F(D4-GR,M,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP734F(D4-GR,M,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared emitting diode with an NPN phototransistor in a DIP-6 plastic package. Key electrical parameters include a minimum collector-emitter breakdown voltage of 55 V, a maximum isolation voltage of 4000 V, and a nominal current transfer ratio of 50%. The device supports operating temperatures from -25 °C to 85 °C and features UL recognition and VDE approval for safety compliance.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Integrates an infrared LED driver with an NPN phototransistor detector
• Certified for safety standards including UL recognition and VDE approval

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (D4, GR, M, or F) against the datasheet to confirm packaging and reel specifications. Confirm RoHS status as the base model may be leaded. Ensure the supplier provides official Toshiba documentation to validate authenticity and traceability before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard current transfer ratio of 50% is required for digital switching applications. Compare with the TLP734 variant if a higher CTR of 100% is needed. Verify that the 55 V collector-emitter voltage rating meets the load requirements of the target circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP73x series of transistor output optocouplers. It shares the same physical package and basic isolation characteristics with variants like TLP733 and TLP734, differing primarily in the specified current transfer ratio and minor electrical tolerances defined by the manufacturer.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include TLP733F(D4-GR,M,F) and TLP734F(D4-GR,M,F). Cross-brand replacements require matching the DIP-6 package, 4000 V isolation, and 55 V Vceo rating.
