FDP6676/FDB6676
30V N-Channel Logic Level PowerTrench MOSFET
General Description
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
“low side” synchronous rectifier operation, providing an
extremely low RDS(ON) .
Applications
• Synchronous rectifier
• DC/DC converter
.
Features
• 42 A, 30 V.
RDS(ON) = 6.0 mΩ @ VGS = 10 V
RDS(ON) = 7.5 mΩ @ VGS = 4.5 V
• Critical DC electrical parameters specified at
elevated temperature
• High performance trench technology for extremely
low RDS(ON)
• 175°C maximum junction temperature rating

Notes:
1. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%
2. TO-220 package is supplied in tube / rail @ 45 pieces per rail.
3. Calculated continuous current based on maximum allowable junction temperature. Actual maximum continuous current limited by package constraints to 75A
