process
Low gate charge and capacitances
- easier to drive
- faster switching
Unclamped Inductive Switching (UIS)
rated
Low R
DS (on)
Fast intrinsic diode
International standard package
miniBLOC
with Aluminium nitride
isolation for low thermal resistance
Low terminal inductance (<10 nH) and
stray capacitance to heatsink (<35pf)
Molding epoxies meet UL 94 V-0
flammability classification
Applications
DC-DC converters
Battery chargers
Switched-mode and resonant-mode
power supplies
DC choppers
Temperature and lighting controls
Advantages
Easy to mount
Space savings
High power density
G = Gate
D = Drain
S = Source
Either Source terminal at miniBLOC can be used
as Main or Kelvin Source
