Vishay SiZ240DT Dual N-Channel 40V (D-S) MOSFET
Vishay SiZ240DT Dual N-Channel 40V (D-S) MOSFET features TrenchFET® Gen IV power MOSFET technology, with integrated high- and low-side MOSFETs in one compact PowerPAIR® 3.3mm2 package. The SiZ240DT provides best-in-class on-resistance and on-resistance times gate charge, a key Figure of Merit (FOM) for MOSFETs used in power conversion applications.
The two TrenchFET MOSFETs in the SiZ240DT are internally connected in a half-bridge configuration. The SiZ240DT’s Channel 1 MOSFET, which is typically used as the control switch in a synchronous buck converter, provides maximum on-resistance of 8.05mΩ at 10V and 12.25mΩ at 4.5V. The Channel 2 MOSFET, which is typically a synchronous switch, features on-resistance of 8.41mΩ at 10V and 13.30mΩ at 4.5V. When combined with a low gate charge of 6.9nC (Channel 1) and 6.5nC (Channel 2), the resulting on-resistance times gate charge FOM enables high efficiency for fast switching applications.
The SiZ240DT features a wire-free internal construction that minimizes parasitic inductance to enable high-frequency switching and thus reduces the size of magnetics and final designs. Its optimized gate-drain charge (Qgd) to gate-source charge (Qgs) ratio reduces noise to further enhance the device's switching characteristics. The SiZ240DT is 100% Rg- and UIS-tested, RoHS compliant, and halogen-free.
