The TLP700F(ABB-TP,F) is an optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Aluminum Arsenide (GaAlAs) infrared emitting diode with a high-speed photodetector IC within a compact 6-lead SDIP package. This configuration provides electrical isolation for driving power MOSFETs and IGBTs in motor inverters and DC-DC converter stages. The device is designed to offer reliable signal transmission between high-voltage and low-voltage circuits while maintaining a small footprint compared to standard 8-pin DIP packages.
This component is officially discontinued and no longer manufactured by Toshiba Semiconductor and Storage. Procurement sources indicate the item is obsolete with unavailable stock. Buyers must verify current availability through authorized distributors or secondary markets, as direct supply from the manufacturer is terminated. Replacement strategies should prioritize manufacturer-recommended substitutes to ensure compatibility.
Selection of this part requires acknowledging its end-of-life status. Designers should evaluate manufacturer-recommended replacement options rather than sourcing obsolete inventory. Verification of pinout compatibility and isolation voltage ratings against new candidates is essential. The compact 6-lead form factor may necessitate PCB layout adjustments when transitioning to alternative components.
The TLP700 series belongs to Toshiba's family of optically isolated gate drivers. These devices utilize integrated photodetectors to provide fast switching speeds suitable for modern power electronics. The specific TLP700F variant distinguishes itself through its reduced 6-lead SDIP packaging, offering a smaller physical profile compared to traditional 8-pin DIP isolators while maintaining necessary isolation performance for industrial applications.
Manufacturer recommended substitutes are available for this obsolete part. Users should consult official documentation for approved replacement part numbers to ensure functional equivalence in gate drive applications.
