TLP5702(TP4,E

Logic Output Optoisolators Overview

The TLP5702(TP4,E is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs infrared LED with an integrated high-speed photodetector IC in a compact 6-SO surface-mount package. The device provides robust electrical isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 20 kV/µs. Key electrical parameters include a typical forward voltage of 1.55 V, a maximum DC forward current of 20 mA, and a peak output current capability of 2.5 A. Propagation delays are specified at a maximum of 200 ns for both high-to-low and low-to-high transitions. The unit supports a drive-side operating voltage range of 15 V to 30 V and features a built-in hysteresis under-voltage lockout function. It operates within a temperature range of -40°C to +110°C.

Logic Output Optoisolators Feature Summary

• Includes a built-in hysteresis under-voltage lockout circuit to ensure stable operation during power-up and shutdown.
• Provides high common-mode transient immunity to prevent false triggering in noisy environments.

Logic Output Optoisolators Applications

• Gate driving for Insulated Gate Bipolar Transistors (IGBTs)
• Gate driving for Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs)
• Industrial equipment requiring galvanic isolation
• Home appliance control circuits

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as TP4, D4, or LF4 may indicate differences in packaging formats like tape-and-reel versus tube. Confirm that the required insulation voltage and thermal performance meet the target application's safety standards. Ensure compatibility with the system's logic levels and drive-side voltage requirements before finalizing the procurement specification.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel, high-speed isolated gate driver is required for IGBT or MOSFET applications. The choice is driven by the need for high common-mode noise immunity and a compact surface-mount footprint. Consider the 2.5 A peak output current and 200 ns propagation delay for switching speed requirements. Verify that the 15 V to 30 V drive-side voltage range aligns with the control circuit design.

Logic Output Optoisolators Part Context

This part belongs to the TLP5702 series of photocouplers designed for industrial and consumer applications. It is distinct from other variants in the family, such as the TLP5701, which offers lower output current capabilities. The TLP5702 series utilizes a 6-pin SOIC package to provide a balance between isolation performance and board space efficiency. It serves as a critical interface component between low-voltage control logic and high-power switching devices.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, verify that any replacement matches the 6-SO package dimensions, 5000 Vrms isolation rating, and 2.5 A peak output current specifications to ensure functional compatibility.
