N-channel Enhancement Mode TOLL MOSFETs with High Conversion Efficiency Designed for EV Applications and Power Management

Diodes Incorporated has introduced a portfolio of automotive MOSFETs that include 100V-rated DMTH10H1M7STLWQ and DMTH10H2M5STLWQ, and 80V-rated DMTH8001STLWQ MOSFETs which occupy 20% less PCB area and feature an off-board profile of 2.4mm. These new MOSFETs in thermally-efficient TOLL package are ideal for use in high reliability power applications, such as energy recuperation, integrated starter alternators, and DC-DC converters in battery-equipped vehicles. The TOLL package uses clip bonding to achieve low package resistance and reduced parasitic package inductance enabling these devices to achieve typical on-resistances of 1.3mΩ, 1.4mΩ, and 1.68mΩ, respectively at a gate drive of 10V. 

These MOSFETs are qualified to AEC-Q101, PPAP capable, and are manufactured in IATF 16949 certified facilities. With a solder contact area that is 50% bigger than the TO263, the TOLL package enables a junction-case thermal impedance of 0.65°C/W, allowing these MOSFETs to handle currents up to 270A. Moreover, their tin-plated trapezoidal grooved leads help to facilitate automated optical inspection (AOI) procedures.
