UPA1915TE(0)-T1-AT-VB Product details
Back to previous pageProduct introduction：
VBsemi UPA1915TE(0)-T1-AT-VB is a single P-channel MOSFET using Trench technology, designed for medium and low voltage negative power rail switching and high-side load control scenarios. Its SOT23-6 small package balances heat dissipation and layout flexibility, suitable for space-constrained high-density PCB designs. The device provides stable switching characteristics within a -30V drain-source voltage range, with gate drive compatible with common 3.3V/5V logic levels for easy system driving, while low on-resistance effectively reduces conduction losses and improves overall system efficiency.
