Si4542DY
30V Complementary PowerTrench^MOSFET
General Description
This complementary MOSFET device is produced using
Fairchild’s advanced PowerTrench process that has
been especially tailored to minimize the on-state
resistance and yet maintain low gate charge for
superior switching performance.
Applications
• DC/DC converter
• Power management
Features
• Q1: N-Channel
6 A, 30 V
R_DS(on) = 28 mΩ @ V_GS = 10V
R_DS(on) = 35 mΩ @ V_GS = 4.5V
• Q2: P-Channel
–6 A, –30 V
R_DS(on) = 32 mΩ @ V_GS = –10V
R_DS(on) = 45 mΩ @ V_GS = –4.5V
