SI300N03UKHE3-TP-VB Product details
Back to previous pageProduct introduction：
SI300N03UKHE3-TP-VB is a small-package, high-reliability N-channel MOSFET in SOT23-3 package, with 30V voltage rating and 5A current capability. Enhanced by Trench technology, it features a low on-resistance of 47mΩ (at 10V drive), resulting in low heat generation and high efficiency. The gate drive is flexible with a wide ±20V range, suitable for most low-voltage control scenarios.
