30 Volt P-Channel PowerTrench® MOSFET
General Description
This P-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers, and battery chargers. These MOSFETs feature faster switching and lower gate charge than other MOSFETs with comparable RDS(ON) specifications. The result is a MOSFET that is easy and safer to drive (even at very high frequencies), and DC/DC power supply designs with higher overall efficiency.
Features
• –13 A, –30 V. RDS(ON) = 9 mΩ @ VGS = –10 V RDS(ON) = 13 mΩ @ VGS = – 4.5 V • Extended VGSS range (±25V) for battery applications • High performance trench technology for extremely low RDS(ON) • High power and current handling capability

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.
