Description
4N60B is 600V, 4A, N-Channel Power MOSFET. These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary, planar, DMOS technology. This advanced technology has been especially tailored to minimize on-state resistance, provide superior switching
performance, and withstand high energy pulse in the avalanche and commutation mode. These devices are well suited for high efficiency switch mode power supplies.
Applications:
1. SMPS
2. PFC
Features
1. Low Qg
2. Low Rdson
3. RoHS compliant
4. Marking : A4N60B P4N60B B4N60B D4N60B I4N60B U4N60B
