The dual MOSFETs released today can be used in place of two discrete devices in the
The SiZF5300DT and SiZF5302DT leverage Vishay’s 30 V Gen V technology for optimal on-resistance and gate charge. The SiZF5300DT provides typical on-resistance of 2.02 mΩ at 10 V and 2.93 mΩ at 4.5 V, while the SiZF5302DT features on-resistance of 2.7 mΩ at 10 V and 4.4 mΩ at 4.5 V. Typical gate charge for the MOSFETs at 4.5 V is 9.5 nC and 6.7 nC, respectively. The resulting ultra low on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — is 35 % lower than that of previous-generation solutions with similar on-resistance. For high frequency switching applications, the result is a 2 % increase in efficiency, allowing for efficiency of 98 % at 100 W.
