MT4606 September 2008 MT4606 Dual N & P-Channel PowerTrench MOSFET General Description These dual N- and P-Channel enhancement mode power field effect transistors are produced using MOS-TECH Semiconductor’s advanced PowerTrench process that has been especially tailored to minimize on-state ressitance and yet maintain superior switching performance. These devices are well suited for low voltage and battery powered applications where low in-line power loss and fast switching are required. Features • Q1: N-Channel 7A, 30V RDS(on) = 0.028Ω @ VGS = 10V RDS(on) = 0.040Ω @ VGS = 4.5V • Q2: P-Channel -5A, -30V RDS(on) = 0.052Ω @ VGS = -10V RDS(on) = 0.080Ω @ VGS = -4.5V • Fast switching speed • High power and handling capability in a widely used surface mount pac [ ... ]
