Description
The Supertex GN2470 is a 700V, 3.5 amp
insulated gate bipolar transistor (IGBT) that
combines the positive aspects of both BJTs and
MOSFETs.
The GN2470 IGBT has lower on-state voltage
drop with high blocking voltage capabilities and
features many desirable properties including a
MOS input gate, low conduction voltage drop at
high currents.
The GN2470 is designed to work with the
Supertex SR03x inductorless dual output off-line
regulators. See the SR03x datasheet for details.
