N-kanals MOSFETs til industrielle strømforsyninger

Toshiba præsenterer 40V, 0.67mohm N-kanals MOSFETs, der bruger den nyeste procesteknologi til at forbedre effektiviteten i strømforsyninger (in english).

Toshiba Electronics Europe introduces the TPHR6704RL, a 40V N-channel power MOSFET fabricated using its latest-generation U-MOS11-H process. The device is optimised for switched-mode power supplies used in data centers, as well as industrial equipment such high-efficiency DC-DC converters, switching voltage regulators, and motor drivers.

By adopting the U-MOS11-H process, the TPHR6704RL achieves a typical drain-source on-resistance (RDS(ON)) of 0.52mohm at a gate-source voltage (VGS) of 10V, and a maximum RDS(ON) of 0.67mohm at a VGS of 10V. 

Compared to the existing 40V product (TPHR8504PL) manufactured using the U-MOS IX-H process, the RDS(ON) is approximately 21% lower. In addition, the switching performance of the new device improves, with a typical total gate charge (Qg) of 88nC and a gate switch charge (QSW) of 24nC, resulting in a reduction in the RDS(ON) × Qg figure-of-merit by approximately 37%, enabling low-loss operation.

TPHR6704RL will help designers to reduce EMI in switched-mode power supplies by minimising voltage spikes generated between the drain and source during switching.

The TPHR6704RL also offers robust current and thermal performance, with a drain current (ID) rating of up to 420A and a channel-to-case thermal resistance of 0.71°C/W at 25°C, enabling stable operation under high-load conditions. The device operates over a wide temperature range, with a maximum channel temperature (Tch) of 175°C, supporting reliable operation in demanding industrial environments.

Housed in the SOP Advance (N) package, the device offers high footprint compatibility with existing SOP Advance designs, simplifying replacement and board-level upgrades.

To support efficient power supply design, Toshiba offers a comprehensive set of circuit design tools. In addition to the G0 SPICE model for rapid functional verification, high-accuracy G2 SPICE models are available to accurately reproduce transient and switching characteristics, helping designers optimise efficiency, EMI, and thermal performance.
