TLP705(D4,F)

Overview

The TLP705(D4,F) is an optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs light-emitting diode and an integrated photodetector within a compact 6-lead SDIP package, which is 50% smaller than standard 8-pin DIPs. The device provides reinforced insulation class compliance suitable for safety-standard equipment. Key electrical parameters include a peak output current of ±0.45 A (max), an operating frequency up to 250 kHz (max), and a supply voltage range of 10 V to 20 V. It features a maximum switching time of 200 ns, a minimum common mode transient immunity of 10 kV/µs, and an isolation voltage of 5000 Vrms (min).

Feature Summary

• Compact 6-lead SDIP package design reduces mounting area while maintaining safety standard requirements.
• Capable of direct gate driving for lower power IGBTs and power MOS FETs.
• Provides reinforced insulation with high common mode transient immunity.

Applications

• Plasma Display Panel gate drive circuits
• Industrial Inverter IGBT gate drive applications
• Power MOS FET gate drive systems

Procurement Notes

Verify the specific suffix configuration against official Toshiba documentation to ensure correct insulation approval status. The D4 option indicates VDE approval under EN60747-5-5 and related standards. Confirm mechanical ratings including creepage and clearance distances match system safety requirements. Check component lifecycle status as discontinuation notifications may apply to older variants.

Selection Notes

Select this component when space constraints require a smaller footprint than traditional 8-pin DIP optocouplers. Ensure the required peak output current meets the load demands, as the maximum is ±0.45 A. Verify that the operating frequency does not exceed 250 kHz. Confirm that the input threshold current and supply voltage ranges align with the control circuit design.

Part Context

This part belongs to the TLP705 series of optically isolated gate drivers designed for industrial and display applications. The series utilizes a GaAlAs LED and integrated photodetector technology. Variants such as TLP705F and TLP705A exist, with differences in packaging or specific approvals. The TLP705(D4,F) specifically denotes the version with VDE approval and tape-and-reel packaging options.
