TLP2955(F)

Logic Output Optoisolators Overview

The TLP2955(F) is a high-speed logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs light-emitting diode with a high-gain, high-speed photo detector in an 8-DIP package. The device provides 5000Vrms isolation voltage and supports operation up to 125°C. Key electrical parameters include a minimum current transfer ratio of 50% at 5mA input, a maximum forward current of 25mA, and a typical CMTI of 20kV/µs. It operates within a temperature range of -40°C to 125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (F) indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the 8-DIP package dimensions match the target PCB footprint. Check for any obsolescence notices or lifecycle changes directly from Toshiba Semiconductor and Storage before finalizing procurement plans.

Logic Output Optoisolators Selection Notes

Select this component when high-speed switching and strong noise immunity are required in isolated digital interfaces. The low input current reduces driver power consumption compared to standard optocouplers. Verify that the 5000Vrms isolation rating meets the safety requirements of the application environment. Consider the 125°C operating limit for high-thermal-stress industrial settings.

Logic Output Optoisolators Part Context

The TLP2955 belongs to Toshiba's high-speed photocoupler family, designed for demanding industrial and automotive applications. It serves as a bridge between low-voltage control logic and higher-voltage power stages. The DIP8 package facilitates through-hole mounting in traditional and mixed-technology circuit boards.
