Vishay Releases Siliconix SiZ240DT, MOSFET Half Bridge Power Stage

October 22, 2020 Perry Cohen

Vishay released the Siliconix SiZ240DT, a 40 V n-channel MOSFET half bridge power stage. It integrates high side and low side MOSFETs in a compact PowerPAIR 3.3mm x 3.3mm package, providing on-resistance and on-resistance times gate charge.

The two TrenchFET® MOSFETs in the SiZ240DT are internally connected in a half-bridge configuration. Its Channel 1 MOSFET provides on-resistance of 8.05 mΩ at 10 V and 12.25 mΩ at 4.5 V. The Channel 2 MOSFET features on-resistance of 8.41 mΩ at 10 V and 13.30 mΩ at 4.5 V.

It provides designers with half-bridge power stages for synchronous buck DC/DC converters, wireless chargers, and switch-mode power supplies in telecom equipment and servers.

It additionally features a wire-free internal construction, minimizing parasitic inductance to allow for high frequency switching. The Qgd / Qgs ratio reduces noise to enhance switching characteristics.
