TLP5771(D4-TP,E

Overview

The TLP5771(D4-TP,E is a one-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photodetector IC to provide galvanic isolation for power device switching. The component operates within a supply voltage range of 10 V to 30 V and delivers a peak output current of 1 A. It features a robust insulation rating of 5000 Vrms, ensuring safety in high-voltage environments. The device is housed in a compact 6-pin SO (SO6L) surface-mount package, designed for efficient PCB layout in industrial and consumer applications.

Feature Summary

• Integrates an infrared LED with a high-gain, high-speed photodetector IC for fast signal transmission
• Provides galvanic isolation suitable for driving IGBTs and MOSFETs in high-noise environments
• Operates with a wide supply voltage range to accommodate various logic levels
• Housed in a compact 6-pin SO package for space-constrained designs

Applications

• Gate drive circuits for IGBTs and MOSFETs in industrial inverters
• Power supplies requiring high-voltage isolation between control and power stages
• Home appliance motor control systems
• Industrial equipment with noisy electrical environments

Procurement Notes

Verify the specific suffix D4-TP against the manufacturer's latest datasheet to confirm packaging type and compliance status. Ensure the ordering part number matches the required reel quantity and RoHS specifications. Cross-reference the manufacturer number with official Toshiba documentation to avoid counterfeit components. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Selection Notes

Select this component when a single-channel gate driver with 5000 Vrms isolation is required. The 1 A output current is sufficient for medium-power MOSFETs and IGBTs. Consider the SO6L package dimensions for board space constraints. Compare with the TLP5772 series if higher peak current (2.5 A) is needed for larger power devices. Ensure the input-output capacitance and propagation delay meet the switching frequency requirements of the target application.

Part Context

This device belongs to the TLP577x series of optically isolated gate drivers from Toshiba. The series is designed to replace traditional transformer-based or discrete isolation solutions. It offers improved reliability and reduced component count by integrating the driver circuitry into a single package. The TLP5771 variant specifically targets applications requiring moderate drive strength with high isolation voltage.

Replacement Considerations

The TLP5772(D4-TP,E is a compatible alternative within the same family, offering a higher peak output current of 2.5 A while maintaining similar isolation and package characteristics. Verify pin compatibility and thermal performance before substitution.
