30V P-Channel PowerTrench MOSFET
General Description
This P-Channel MOSFET is a rugged gate version of Fairchild Semiconductor’s advanced PowerTrench process. It has been optimized for power management applications requiring a wide range of gate drive voltage ratings (4.5V – 20V).
Features
• –4.5 A, –30 V RDS(ON) = 40 mΩ @ VGS = –10 V RDS(ON) = 70 mΩ @ VGS = –4.5 V • Extended VGSS range (±20V) for battery applications • High performance trench technology for extremely low RDS(ON) • Low profile TSSOP-8 package
Applications
• Battery protection • DC/DC conversion • Power management • Load switch

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. a) RθJA is 87 °C/W (steady state) when mounted on a 1 inch² copper pad on FR-4.
b) RθJA is 114 °C/W (steady state) when mounted on a minimum copper pad on FR-4. 2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%
