Bruckewell Technology Corp., Ltd. MSQ7434N Dual N-Channel 30-V (D-S) MOSFET These miniature surface mount MOSFETs utilize a high cell density trench process to provide low RDS (on) and to ensure minimal power loss and heat dissipation. Typical applications SOIC-8PP are DC-DC converters and power management in portable and battery-powered products such as computers, printers, PCMCIA cards, cellular and cordless telephones. Key Features: • Low rDS(on) provides higher efficiency and • extends battery life • Low thermal impedance copper leadframe • SOIC-8 saves board space • Fast switching speed • High performance trench technology Absolute Maximum Ratings Parameter (Tc=25°C unless otherwise noted) Symbol Value Unit Drain-Source Voltage VDS 30 V Gate-Source Voltage VGS ±20 V Continuous Drain Current @ TC=25°C ID 24 A Continuous Drain Current @ TC=70°C ID 20 A IDM 60 A IS 2.9 A 5.0 W 3.2 W -55~+150 °C Pulsed Drain Current Continuous Source Current (Diode Conduction) Power Dissipation (TC=25°C) PD Power Dissipation (TC=100°C) Operating Junction and Storage Temperature Tj, Tstg Notes a.
