TLP5772(D4,E

Logic Output Optoisolators Overview

The TLP5772(D4,E) is an optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photo-IC to provide robust signal isolation. The device features a push-pull output capable of sourcing or sinking up to 2.5A, making it suitable for driving power devices like IGBTs and MOSFETs. It offers a 5000Vrms isolation voltage and a minimum common-mode transient immunity (CMTI) of 35kV/µs. Key electrical parameters include a maximum propagation delay of 150ns, typical rise and fall times of 56ns and 25ns respectively, and a forward current maximum of 8mA. It operates within a supply voltage range of 10V to 30V and supports a wide operating temperature range from -40°C to +125°C.

Logic Output Optoisolators Feature Summary

• High peak output current capability of 2.5A for direct gate drive applications
• Enhanced noise immunity with 35kV/µs minimum common-mode transient rejection
• Wide operating temperature range extending to +125°C for harsh environments
• Compact 6-pin SO package design for space-constrained PCB layouts

Logic Output Optoisolators Applications

• IGBT gate drive circuits in industrial motor drives
• MOSFET gate drivers for switching power supplies
• Inverter systems for renewable energy applications
• Isolated control interfaces in high-voltage equipment

Logic Output Optoisolators Procurement Notes

Verify the specific suffix D4,E against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the selected packaging format aligns with automated assembly requirements. Cross-reference the component marking with the original manufacturer documentation to prevent counterfeit substitution. Confirm RoHS compliance status if required by your manufacturing standards.

Logic Output Optoisolators Selection Notes

Select this component when high peak current drive is necessary for fast-switching power semiconductors. The 2.5A output capability distinguishes it from standard logic isolators. Consider the 35kV/µs CMTI rating for noisy environments with rapid voltage transitions. Verify that the 10V to 30V supply range matches your system's available voltage rails and that the 6-SO package fits your board footprint constraints.

Logic Output Optoisolators Part Context

This part belongs to the TLP577x series of optically isolated gate drivers from Toshiba. It is designed specifically for driving power devices where electrical isolation between control and power stages is critical. The series includes variants with different temperature ratings and packaging options, such as the TLP5772H for extended temperature ranges. It serves as a bridge between low-power logic controllers and high-power switching elements.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba parts within the TLP577x family, such as the TLP5772(TP,E) for standard temperature operation or the TLP5772H(D4,E) for higher temperature variants. Verify pin-to-pin compatibility and ensure equivalent current drive capabilities before substitution.
