Fairchild circuit protection is proud to offer a new type of
reverse bias protection devices. The FR devices are low
resistance, series switches that, in the event of a
reverse bias condition, shut off power and block the
negative voltage to help protect downstream circuits.
USB Tested and Compatible
The FR devices are optimized for the application to offer
best in class reverse bias protection and voltage
capabilities while minimizing size, series voltage drop,
and normal operating power consumption.

USB Charging
In the event of a reverse bias application, FR011L5J
devices effectively provide a full voltage block and can
easily protect -0.3V rated silicon.
Mobile Devices
Mobile Medical
POS Systems
From a power perspective, in normal bias, an 11mΩ FR
device in a 1.5A application will generate only 17mV of
voltage drop or 25mW of power loss. In reverse bias,
FR devices dissipate less then 20µW in a 16V reverse
bias event. This type of performance is not possible with
a diode solution.

Benefits extend beyond the device. Due to low power
dissipation, not only is the device small, but heat sinking
requirements and cost can be minimized as well.
