UPA1803GR-VB MOSFET Product Introduction
The UPA1803GR-VB is a unipolar N-type MOSFET in a TSSOP8 package, designed for high-performance, low-voltage applications. The device has a maximum drain-source voltage (V_DS) of 30V, and a gate-source voltage (V_GS) that can withstand a voltage range of ±20V. The UPA1803GR-VB has a low on-resistance of 14.4mΩ (V_GS = 4.5V) and 12mΩ (V_GS = 10V), which gives it excellent current conduction capability and low power loss, making it suitable for high-efficiency power supply designs. Its maximum drain current (I_D) is 8.5A, which can support medium-power applications. Using Trench technology, the UPA1803GR-VB provides excellent switching performance and is very suitable for use in power management, load switching, and drive circuits.
