SI2122DS-T1-GE3-VB Product details
Back to previous pageProduct introduction：
SI2122DS-T1-GE3-VB is an N-channel MOS transistor in SOT23-3 package, with 100V withstand voltage and 4.3A current capacity. The Trench process brings low on-resistance and fast switching characteristics. With a 10V drive, the on-resistance is only 100mΩ, resulting in low loss and high reliability. A ±20V wide gate drive range makes it compatible with various control circuits, making it an ideal choice for small-package high-voltage power switches.
