TLP5752(D4-TP,E

Overview

The TLP5752(D4-TP,E is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED emitter with a high-speed photo-IC output stage designed for driving IGBTs and MOSFETs. The device provides a peak output current of 2.5A at both high and low states, supporting supply voltages between 15V and 30V. Key electrical specifications include a maximum propagation delay of 150ns, typical rise and fall times of 15ns and 8ns respectively, and a minimum common-mode transient immunity of 35kV/µs. It operates within a temperature range of -40°C to +110°C and features a 5000Vrms isolation voltage in a 6-SO package.

Feature Summary

• High peak output current capability of 2.5A for robust gate drive performance
• Optical coupling technology ensuring high-voltage isolation between input and output circuits
• Fast switching characteristics with low propagation delay and minimal pulse width distortion
• High common-mode transient immunity to prevent false triggering in noisy environments

Applications

• IGBT gate driving in industrial motor drives
• MOSFET gate driving in power conversion systems
• Inverter circuits for renewable energy applications
• Switching power supplies requiring galvanic isolation

Procurement Notes

Verify the specific suffix (D4-TP,E) against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure the ordering quantity matches the required reel or tube configuration. Confirm that the lead time aligns with project schedules as availability may vary. Cross-reference the component marking with the physical device to prevent counterfeit substitution. Validate that the insulation voltage ratings meet the safety requirements of the target application design.

Selection Notes

Select this component when a single-channel gate driver with high current capability and robust isolation is required. The 2.5A output current suits medium-power IGBT and MOSFET applications. Consider the 6-SO package size for PCB layout constraints. Evaluate the 35kV/µs CMTI rating against the noise environment of the power stage. Compare the propagation delay specifications with system timing requirements to ensure adequate switching speed without excessive losses.

Part Context

This part belongs to the TLP5752 series of photocouplers from Toshiba, specifically designed for gate drive applications. The series typically includes variants with different packaging options such as tubes or reels, and varying certification marks like UL, VDE, or CSA. The D4-TP,E designation indicates a specific tape-and-reel packaging format compliant with RoHS standards. These devices are engineered to replace discrete optocoupler and driver combinations, simplifying circuit design while maintaining high reliability in power electronics.

Replacement Considerations

Direct replacements include other TLP5752 variants such as TLP5752(D4,E or TLP5752(LF4,E, provided the packaging and certification requirements match. Verify pinout compatibility and electrical parameters before substitution. Ensure the alternative part meets the same isolation voltage and current drive specifications.
