SI4435DY
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 gave drive voltage ratings (4.5V – 25V).
Applications
· Power management
· Load switch
· Battery protection
Features
· –8.8 A, –30 V RDS(ON) = 20 mW @ VGS = –10 V
RDS(ON) = 35 mW @ VGS = –4.5 V
· Low gate charge (17nC typical)
· Fast switching speed
· High performance trench technology for extremely low RDS(ON)
· High power and current handling capability
Absolute Maximum Ratings TA=25℃ unless otherwise noted
