TLP5702H(D4LF4,E

Logic Output Optoisolators Overview

The TLP5702H(D4LF4,E is a single-channel optically isolated gate drive coupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photodetector IC in a compact SO-6L surface-mount package. The device provides robust electrical isolation with a rated insulation voltage of 5000 Vrms and a minimum common-mode transient immunity (CMTI) of 50 kV/µs. Key electrical parameters include a maximum propagation delay of 200 ns, a typical rise time of 37 ns, and a typical fall time of 50 ns. It operates within a temperature range of -40°C to +125°C and supports a forward current of up to 20 mA.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix D4LF4 against the official Toshiba datasheet to confirm lead-free status and packaging type. Ensure the procurement channel sources from authorized distributors to guarantee component authenticity. Confirm that the required insulation voltage and CMTI ratings meet the safety standards of the target application design.

Logic Output Optoisolators Selection Notes

Select this component when high-speed switching and strong noise immunity are required for gate drive applications. The SO-6L package offers a compact footprint suitable for space-constrained designs. Consider the 5000 Vrms isolation rating for applications requiring significant potential difference between control and power sides.

Logic Output Optoisolators Part Context

This part belongs to the TLP570xH series of optically isolated gate drive couplers designed for driving IGBTs and MOSFETs. These devices replace traditional transformer-based or discrete optocoupler solutions by integrating the driver functionality into a single package. The series is characterized by high speed, high gain, and robust isolation capabilities.

Logic Output Optoisolators Replacement Considerations

Check for other variants within the TLP570xH family, such as TLP5702H(E), which may differ only in packaging quantity or reel specifications. Verify pinout compatibility before substituting with other manufacturers' gate drive couplers.
