FAIRCHILD SI4542

Si4542DY
30V Complementary PowerTrenchMOSFET
General Description
Features
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.

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
