SI4953BDY-T1-E3-VB Product details
Back to previous pageProduct introduction：
The SI4953BDY-T1-E3-VB is a dual P-channel power MOSFET in a SOP8 package, featuring a -30V drain-source voltage and -7.3A current capability. Utilizing Trench technology, it achieves a low on-resistance of 35mΩ at 10V drive and 45mΩ at 4.5V drive, resulting in low heat generation and high efficiency. With a flexible gate drive range of ±20V, it is suitable for most low-voltage control and load switching applications.
