TLP5754H(TP4,E

Overview

The TLP5754H(TP4,E is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photodetector IC in a 6-pin SO-6L (SOIC) stretched package. The device provides galvanic isolation of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum propagation delay of 150 ns, rise time of 15 ns, and fall time of 8 ns. It supports a peak output current of 4 A and operates within a temperature range of -40°C to +125°C. The typical forward voltage is 1.55 V, and the power dissipation is rated at 810 mW.

Feature Summary

• Integrates an infrared LED with a high-gain, high-speed photodetector for efficient optical coupling
• Provides robust galvanic isolation capability suitable for high-voltage switching applications
• Features fast switching characteristics with low propagation delay and minimal pulse width distortion

Applications

• Gate drive coupling for IGBTs and MOSFETs in industrial inverters
• Power supply control circuits requiring high common-mode transient immunity
• Isolated interfaces in motor drive systems

Procurement Notes

Verify the specific suffix TP4 against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the procurement source provides valid UL, CSA, or cUL certification documents if safety isolation is required for the end application. Cross-reference the RoHS compliance status with current environmental regulations.

Selection Notes

Select this component when a single-channel isolated gate driver with high speed and moderate peak current is required. The wide operating temperature range makes it suitable for demanding industrial environments. Consider the SO-6L package dimensions for PCB layout constraints and ensure the isolation voltage rating meets the system's creepage and clearance requirements.

Part Context

This part belongs to the TLP5754H series of optically isolated gate drivers from Toshiba. The series is designed to replace traditional transformer-based gate drives, offering compact size and simplified circuit design. The TLP5754H variant specifically denotes the standard version with defined thermal and electrical characteristics for general-purpose high-frequency switching applications.

Replacement Considerations

Direct substitutes may include other single-channel isolated gate drivers from Toshiba such as the TLP5754 or TLP5774 series, provided pin compatibility and electrical specifications match. Verify that alternative components meet the same isolation voltage and speed requirements.
