SI9933DY-T1-E3-VB Product details
Back to previous pageProduct introduction：
SI9933DY-T1-E3-VB is a dual P-channel MOSFET in an SOP8 package, with -30V withstand voltage and -7.3A current capability. Enhanced by Trench technology, the on-resistance is as low as 35mΩ (10V drive), resulting in low heat generation and high efficiency. The gate drive is flexible, with a ±20V wide range, suitable for most low-voltage control scenarios. The dual-transistor integrated design saves board space, ideal for compact power supply and switching circuits.
