SI4300DY-T1-E3-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power-density DC-DC module with limited board area, yet need to handle 12A continuous current and stringent thermal challenges? Ordinary MOS transistors either have high conduction losses or demanding drive requirements. The VBsemi SI4300DY-T1-E3-VB is designed for this—it integrates 30V withstand voltage, 12A current carrying capability, and an on-resistance of only 11.5mΩ into a standard SOP8 package, allowing compact power supply designs to achieve an ideal balance between performance and size.
