2.5A, 500V, 3.000 Ohm, N-Channel Power
MOSFETs
Features
• 2.5A, 500V
These are N-Channel enhancement mode silicon gate
power field effect transistors. They are advanced power
MOSFETs designed, tested, and guaranteed to withstand a
specified level of energy in the breakdown avalanche mode
of operation. All of these power MOSFETs are designed for
applications such as switching regulators, switching
convertors, motor drivers, relay drivers, and drivers for high
power bipolar switching transistors requiring high speed and
low gate drive power. These types can be operated directly
from integrated circuits.
• r = 3.000Ω
DS(ON)
• Single Pulse Avalanche Energy Rated
• SOA is Power Dissipation Limited
• Nanosecond Switching Speeds
• Linear Transfer Characteristics
• High Input Impedance

Quality and reliability
These are N-Channel enhancement mode
silicon gate power field effect transistors. They
are advanced power MOSFETs designed,
tested, and guaranteed to withstand a specified
level of energy in the breakdown avalanche
mode of operation. All of these power
MOSFETs are designed for applications such
as switching regulators, switching convertors,
motor drivers, relay drivers, and drivers for
high power bipolar switching transistors
requiring high speed and low gate drive power.
These types can be operated directly from
integrated circuits.
