SI2399BDS-T1-GE3-VB Product details
Back to previous pageProduct introduction：
SI2399BDS-T1-GE3-VB is a compact, low-loss P-channel MOSFET in a SOT23-3 package, with a withstand voltage of -20V and supporting -5A continuous current. The Trench process provides excellent conduction characteristics, with an on-resistance as low as 34mΩ at 4.5V drive, resulting in low switching loss and minimal heat generation. With a wide ±12V gate drive voltage range, it is suitable for various low-voltage control circuits, especially for load switch and power management applications in portable devices.
