Description:
The K4111 is 600V, 10A, Silicon N Channel MOS Type (π−MOSIII) Field Effect Transistor.
In an N-channel MOSFET, the source and drain terminals are connected to an N-type semiconductor material, while the gate terminal is insulated from the channel by a thin oxide layer. When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals.
Features:
1. Low drain-source ON resistance: RDS (ON)= 0.54 Ω(typ.)
2. High forward transfer admittance: |Yfs| = 8.5S (typ.)
3. Low leakage current: IDSS= 100 μA (max) (VDS= 600 V)
4. Enhancement mode: Vth= 2.0 to 4.0 V (VDS= 10 V, ID= 1 mA)
Pinout
Absolute Maximum Ratings (Ta = 25°C)
