TLP759(LF1,J,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP759(LF1,J,F) is a high-speed optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Arsenide infrared emitting diode with a high-speed photodiode-transistor detector on a single chip, housed in an 8-lead DIP package. The device features a Faraday shield integrated into the photodetector to provide effective common-mode noise transient immunity. Key electrical parameters include a minimum isolation voltage of 5000 Vrms, a typical propagation delay low-to-high of 0.3 μs, and a typical propagation delay high-to-low of 0.2 μs at RL=1.9 kΩ. It operates within a temperature range of -55°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (LF1, J, F) against the manufacturer's current datasheet to confirm pinout compatibility and regulatory approvals such as UL or VDE recognition. Ensure the ordering code matches the required packaging format and lead-free status. Cross-reference the component revision history to confirm that internal design changes have not altered the functional specifications or mechanical dimensions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation with strong noise immunity is required. The integrated Faraday shield makes it suitable for noisy environments where standard optocouplers might fail. Verify that the input forward current and output collector current requirements align with the circuit design limits. Consider the operating temperature range and insulation thickness requirements for safety compliance in the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

The TLP759 belongs to Toshiba's high-speed photocoupler series designed for robust signal transmission across isolated grounds. It replaces older transistor-output optocouplers by offering faster switching speeds and better noise rejection due to the photo-diode-transistor architecture. This family is widely used in industrial and consumer electronics requiring reliable galvanic isolation between microprocessor systems and power stages.
