Renesas Electronics TP65B110HRU Bi-Directional Switch (BDS)

Renesas Electronics TP65B110HRU Bi-Directional Switch (BDS) is a 650V and 110mΩ normally-off Gallium Nitride (GaN) BDS in a compact TOLT package. This BDS conducts current and blocks voltage in both directions, combining a high-voltage depletion-mode GaN with low-voltage normally-off silicon MOSFETs. The TP65B110HRU BDS is based on the SuperGaN® Gen 1 bidirectional platform.  This BDS delivers superior performance, standard gate‑drive compatibility, easy integration, and robust reliability. The TP65B110HRU BDS offers breakthrough integration, resulting in reduced component count, lower cost, and a smaller footprint. This BDS enables ultra-fast switching, high efficiency, and higher power density, and is ideal for MHz-class operation and compact magnetics. Typical applications include solar inverters, AI infrastructure, automotive OBC, motor drives, and AC/DC and DC/DC single-stage power conversion architectures.

Features

  • High noise immunity, easy to drive, and compatible with standard silicon drivers, with no negative voltage required
  • Robust and reliable performance in high-speed soft-switching and hard-switching applications enabled by high dv/dt immunity
