TLP5774H(E

Overview

The TLP5774H(E) is a single-channel optically isolated gate driver featuring a 5000 Vrms insulation voltage. It delivers a peak output current of 4 A with a typical rise time of 56 ns and fall time of 25 ns. The device operates within a temperature range of -40°C to +125°C, supports a forward current of 8 mA, and has a power dissipation of 20 mW. It utilizes a 6-SO surface-mount package.

Feature Summary

• Provides high-voltage galvanic isolation for safe control of power switches
• Delivers strong drive capability for IGBTs and MOSFETs
• Ensures signal integrity through high common-mode transient immunity

Applications

• Industrial motor drives and inverters
• Switching power supplies and converters
• Induction heating systems

Procurement Notes

Verify the specific suffix (e.g., E, D4TP4, D4LF4) against the datasheet to confirm packaging type and lead times. Ensure the selected variant matches the required insulation certifications such as VDE or UL for the target application region. Confirm RoHS compliance status during procurement.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required for gate driving applications. Consider the 6-SO package dimensions for PCB layout constraints. Evaluate the thermal performance given the 20 mW power dissipation limit in high-temperature environments up to 125°C.

Part Context

This part belongs to Toshiba's TLP5774 series of photocouplers designed for industrial power electronics. It integrates an infrared LED emitter with a photo-IC output stage to provide robust isolation between low-voltage control circuits and high-voltage power stages.

Replacement Considerations

Check for direct substitutes within the TLP5774 family, such as TLP5774H(D4TP4,E), which may offer different reel packaging options while maintaining identical electrical characteristics and pinout compatibility.
