TOSHIBA 2SK3878 N-Channel MOSFET Transistor 900V 9A 2−16C1B
The TOSHIBA 2SK3878 is a Silicon N-Channel MOS Type (π- MOSIV) field-effect transistor. It operates in enhancement mode and is specifically designed to provide highly efficient performance and reliable high-voltage operation. This component is supplied in a standard TOSHIBA 2-16C1B package (JEITA SC-65 compliant).
Features
- Low drain-source ON-resistance: RDS(ON) = 1.0 Ω (typ.)
- High forward transfer admittance: |Yfs| = 7.0 S (typ.)
- Low leakage current: IDSS = 100 μA (max) (VDS = 720 V)
- Enhancement model: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA)
