Description
This is Silicon N-Channel MOSFET (2SK3878).
Applications:
Switching Regulator
Features
1. Low drain-source ON-resistance: RDS (ON) = 1.0 Ω (typ.)
2. High forward transfer admittance: ⎪Yfs⎪ = 7.0 S (typ.)
3. Low leakage current: IDSS = 100 μA (max) (VDS = 720 V)
4. Enhancement model: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA) Unit: mm
