TLP627-4(PP,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP627-4(PP,F) is a quad-channel photocopler manufactured by Toshiba Semiconductor and Storage. It integrates four independent channels, each consisting of an infrared LED optically coupled to a Darlington-connected phototransistor with an integrated base-emitter resistor. This configuration optimizes switching speed and high-temperature performance. The device features a minimum collector-emitter voltage of 300V, a typical current transfer ratio of 4000%, and a minimum isolation voltage of 5000Vrms. It operates within a temperature range of -25°C to 85°C and utilizes a PDIP-16 package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix PP against official Toshiba documentation to confirm pin assignment or lead finish variations compared to standard variants. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated DC output channels are required in a compact form factor. The integrated base-emitter resistor simplifies circuit design by reducing external component count. Consider the 40µs rise time limitation; it is suitable for general-purpose switching but may not support high-frequency data transmission applications requiring faster response times.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP627 series, which includes single (TLP627), dual (TLP627-2), and quad (TLP627-4) channel configurations. All variants share identical internal optical and electrical characteristics per channel, differing only in the number of isolated circuits provided within the plastic DIP package. The series is designed for industrial and commercial control systems requiring reliable galvanic isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include TLP627-2 for reduced channel counts or TLP627 for single-channel applications. Verify that replacement parts maintain the same Darlington output structure and isolation voltage ratings to ensure circuit compatibility without redesign.
