Description
The FJAFS1720 is a low-cost, high-performance power
switch designed to provide the best performance when
used in an ESBCconfiguration in applications such as:
power supplies, motor drivers, smart grid, or ignition
switches. The power switch is designed to operate up to
1700 volts and up to 12 amps, while providing exception-
ally low on-resistance and very low switching losses.
The ESBCswitch is designed to be driven using off-the-
shelf power supply controllers or drivers. The ESBC
MOSFET is a low-voltage, low-cost, surface-mount
device that combines low-input capacitance and fast
switching, The ESBCconfiguration further minimizes
the required driving power because it does not have
Miller capacitance.
The FJAFS1720 provides exceptional reliability and a
large operating range due to its square reverse-bias-safe-
operating-area (RBSOA) and rugged design. The device
is avalanche rated and has no parasitic transistors, so is
not prone to static dv/dt failures.
The power switch is manufactured using a dedicated
high-voltage bipolar process and is packaged in a high-
voltage TO-3PF package.
