TLP733(D4-GR,M,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP733(D4-GR,M,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a gallium arsenide infrared LED coupled to an NPN phototransistor within a DIP-6 plastic package. Key electrical specifications include a minimum collector-emitter breakdown voltage of 55 V, a maximum insulation voltage of 4000 Vrms, and a nominal current transfer ratio of 100%. The device supports a maximum forward current of 60 mA and operates within a temperature range of -25 °C to 85 °C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-speed switching capabilities suitable for digital signal isolation applications
• Ensures robust electrical safety through certified UL recognition and VDE approval
• Delivers high current transfer efficiency with a nominal CTR of 100%

Transistor, Photovoltaic Output Optoisolators Applications

• Digital communication interface isolation
• Microprocessor system input/output isolation
• Solid-state relay driver circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix codes (D4, GR, M, F) against the manufacturer's datasheet to confirm exact packaging, lead finish, and compliance status. Confirm RoHS and REACH compliance requirements as standard versions may contain lead. Ensure the ordering code matches the required insulation certification standards for your target market.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a high current transfer ratio is required for efficient logic level translation. The 55 V collector-emitter breakdown voltage provides adequate headroom for low-voltage logic circuits. Verify that the DIP-6 package dimensions fit the PCB layout constraints and that the operating temperature range meets the environmental conditions of the final assembly.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP733 series of transistor output optocouplers from Toshiba. It shares the same internal circuit topology as variants like the TLP734 but differs in specific electrical characteristics such as the current transfer ratio. The series is designed for general-purpose digital isolation in industrial and consumer electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other Toshiba models within the TLP73x family, such as the TLP734 or TLP732, provided their specific CTR and pinout configurations match the design requirements. Cross-manufacturer replacements require verification of pin compatibility, isolation voltage ratings, and CTR specifications.
