MDDG04R06Q
40V N-Channel Enhancement Mode MOSFET
1. Description
This N-Channel MOSFET is produced using MDD Semiconductor's advanced Power Trench process that
incorporates Shielded Gate technology. This process has been optimized to minimize on-state resistance and yet
maintain superior switching performance with best in class soft body diode.
2. Features
• Max RDS(on) = 5.5 mΩ at VGS = 10 V, ID = 20A
• 100% UIS Tested
• 100% dVDS Tested
3. Application
• Synchronous Rectification for ATX / Server / Telecom PSU
• Motor Drives and Uninterruptible Power Supplies
• Micro Solar Inverter
• DC to DC converters
4. Absolute Maximum Ratings(TA=25°C unless otherwise noted)
