TLP718(F)

Overview

The TLP718(F) is a high-speed optocoupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with a push-pull totem pole output configuration. The device utilizes an infrared emitting diode coupled with an integrated high-gain, high-speed photodetector. Key electrical parameters include a forward current of 5 mA, a forward voltage of 1.6 V, and a reverse voltage rating of 5 V. It offers an insulation voltage of 5000 Vrms and a common-mode transient immunity of 10 kV/µs. Timing characteristics specify rise and fall times of 30 ns each, supporting data rates up to 5 Mbps. The component operates within a temperature range of -40°C to +100°C and is housed in a 6-pin SDIP gull-wing package.

Procurement Notes

Verify the specific suffix designation, as the (F) variant indicates tape-and-reel packaging while other suffixes may denote tube packaging. Confirm RoHS compliance status through official documentation. Check for product discontinuance notifications or lifecycle changes prior to procurement. Ensure the selected package type matches the intended surface-mount assembly process. Validate that the 5000 Vrms isolation rating meets the safety requirements of the target application.

Selection Notes

Select this component when high-speed digital isolation is required between circuits with significant ground potential differences. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 10 kV/µs CMTI rating for applications involving noisy switching environments. Ensure the 5 mA forward current requirement aligns with the driving source capabilities. Verify that the SDIP-6 package dimensions fit the available PCB footprint constraints.

Part Context

The TLP718 belongs to Toshiba's family of high-speed optocouplers designed for digital communication and isolation tasks. It serves as a bridge between low-voltage logic circuits and higher-voltage or noisy domains. The integration of a GaAs IRED and high-speed photodetector enables performance superior to standard transistor-output optocouplers. This series is commonly utilized in industrial automation and computing systems requiring reliable signal transfer across isolation barriers.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Cross-reference with Toshiba's official replacement guides or consult manufacturer support for equivalent high-speed optocouplers with matching pinouts and electrical specifications.
