TLP754(TP1,F)

Overview

The TLP754(TP1,F) is a logic output optoisolator featuring an open collector configuration. It integrates a GaAlAs infrared LED with a high-speed photodetector IC in an 8-DIP package. Key electrical parameters include a minimum isolation voltage of 5000 Vrms and a common-mode transient immunity of ±20 kV/µs. The device operates within a supply voltage range of -0.5 to 30 V, with a maximum threshold input current of 5.0 mA and supply current of 1.3 mA. Propagation delay times are specified at tpHL = 400 ns (max) and tpLH = 550 ns (max), with pulse width distortion limited to 400 ns (max). Operating temperature spans from -40°C to 125°C.

Procurement Notes

This component is officially marked as obsolete by Toshiba Semiconductor and Storage and is no longer manufactured. Procurement should focus on verified manufacturer-recommended substitutes rather than sourcing existing inventory. Verify that replacement parts meet the original isolation voltage, speed, and thermal requirements. Ensure substitute components maintain compatible pinouts and logic configurations to prevent redesign efforts.

Selection Notes

Select this component when high-speed digital isolation is required between control ICs and power stages. The open collector output suits applications needing pull-up resistor flexibility. Consider the ±20 kV/µs CMTI for noisy industrial environments. Verify that the DIP8 package fits the PCB layout constraints. Ensure the operating temperature range covers the specific application environment extremes.

Part Context

The TLP754 belongs to Toshiba’s series of photocouplers designed for high-speed logic isolation. It combines an infrared LED with an integrated photodetector IC to provide fast signal transmission while maintaining electrical separation. This family emphasizes reliability in motor control and industrial power applications where noise immunity and precise timing are critical.

Replacement Considerations

Manufacturer recommended substitutes are available. Verify that alternative parts match the 8-DIP package, 5000 Vrms isolation, and open collector output type. Ensure substitute components support the same supply voltage range and operating temperature limits.
