TLP5771H(D4TP4,E

Overview

The TLP5771H(D4TP4,E is a single-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It features a 1A output current capability with a 5000 Vrms isolation voltage rating. The device operates within a temperature range of -40°C to +125°C. Key electrical parameters include a forward voltage of 1.65 V, a reverse voltage of 5 V, and a maximum forward current of 8 mA. Power dissipation is rated at 20 mW. Timing characteristics specify a rise time of 56 ns and a fall time of 25 ns. The component is housed in a surface-mount package.

Feature Summary

• Provides high-speed optical coupling for gate drive applications
• Ensures safety through 5000 Vrms insulation voltage
• Supports operation in high-temperature environments up to 125°C

Applications

• Gate drive coupling for power semiconductor switches
• High-temperature industrial inverter systems
• Isolated control interfaces for motor drives

Procurement Notes

Verify the specific suffix D4TP4,E to confirm the reel packaging format and lead width variations compared to standard tube packages. Ensure compatibility with RoHS directives and VDE certification requirements for your target market. Cross-reference the manufacturer part number against official Toshiba documentation to distinguish between different pinout or thermal specifications within the TLP5771H family.

Selection Notes

Select this component when a single-channel gate driver with 1A peak output is required alongside robust galvanic isolation. Consider the 56 ns rise and 25 ns fall times for switching speed requirements. Evaluate the -40°C to +125°C operating range against environmental conditions. Confirm that the 6-SO surface mount package fits the PCB layout constraints and that the 5000 Vrms isolation meets system safety standards.

Part Context

This part belongs to the TLP5771H series of photocouplers designed specifically as gate drive couplers. It integrates an infrared LED input side with a photo IC output stage to transmit gate drive signals across an isolation barrier. The series is characterized by high common-mode transient immunity and wide operating temperature ranges suitable for demanding power electronics applications.
