TLP627-4(HITOMK,F) is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Toshiba Semiconductor and Storage. Its product description is PHOTOCOUPLER. Review the specifications below when checking this part for your BOM.
The TLP627-4(HITOMK,F) is a quad-channel photodarlington optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates four infrared emitting diodes with four Darlington-connected phototransistors, each featuring an integrated base-emitter resistor to optimize switching speed and high-temperature characteristics. The device provides 5000 Vrms isolation voltage and supports a collector-emitter voltage of up to 300 V. It operates within a temperature range of -25°C to 85°C and is housed in a 16-pin DIP package.
Verify the specific suffix (HITOMK,F) against official Toshiba documentation to confirm compliance with regional safety standards such as UL, CSA, or VDE. Ensure the procurement channel sources genuine components from authorized distributors to avoid counterfeit parts. Confirm that the package type matches the required PCB footprint and that the operating temperature range meets the application's environmental specifications.
Select this component when multiple isolated channels are required in a single package to save board space. The integrated base-emitter resistors make it suitable for applications requiring faster switching speeds compared to standard phototransistor outputs. Consider the 5000 Vrms isolation rating for systems requiring robust galvanic separation between control and load circuits.
This part belongs to the TLP627 series, which includes dual-channel variants like the TLP627-2. The series is characterized by its use of gallium arsenide infrared LEDs coupled with Darlington phototransistors. The quad configuration distinguishes it from other members of the family by offering four isolated paths in a 16-pin DIP format.
Direct substitutes include the TLP627-4(F) and TLP627-4(LF1,F). Verify pinout compatibility and electrical parameters before substitution.
