SI7405DN-VB Product details
Back to previous pageProduct introduction：
The SI7405DN-VB is a small-sized, high-current P-channel MOS tube in a DFN8(3X3) package, with -20V withstand voltage and -15A current carrying capacity. With Trench technology, the internal resistance is as low as 16mΩ (4.5V drive), resulting in low heat generation and high efficiency. The gate drive is flexible with a wide range of ±8V, suitable for most low-voltage load switch and power management scenarios.
