PLANO, Texas -- April 23, 2013

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier
of high-quality application specific standard products within the broad
discrete, logic and analog semiconductor markets, today introduced a new
family of current-limited power switches offering high current handling in an
ultra-small (2mm x 2mm) package. The new power switches enable power density
to be increased in the protection of multiple USB3.0 ports used in
applications such as set-top boxes, LED TVs and notebook computers. The six
new single-channel devices introduced have an on-resistance of only 70mΩ,
cover maximum continuous output currents up to 2.5A and are being made
available in the miniature footprint U-DFN2020-6 package.

For any applications subject to heavy capacitive loads and a possibility of
short circuit, the switches provide a robust port protection solution,
comprising reverse-current blocking, over-current, over-temperature,
under-voltage lockout and short-circuit protection. All devices also integrate
an output discharge function to ensure controlled discharging of the output
capacitor. In addition, the switches’ fast short-circuit response time of 2µs
prevents any unnecessary system shutdown or restart.

With an input voltage range of 2.7V to 5.5V, all devices are suited for 3.3V
and 5V rail systems in a variety of product designs including set-top boxes,
LED TVs and notebooks. Supporting a maximum continuous output current of 2.5A,
the AP2501 and AP2511 are, respectively, active-low and active-high enabled
and are footprint-compatible with the AP2301 and AP2311 devices handling a 2A
continuous output current.

The AP2401 and AP2411 are also 2A rated power switches but provide in addition
an output latch-off function that responds to an over current excursion,
enabling further optimization of fault behaviour management. All six power
switches also feature an open-drain, over-current fault flag with a 7ms
deglitch time to prevent false reporting.

As well as the U-DFN2020-6 package, the devices are also offered in SO8,
MSOP-8/EP and U-DFN3030-8 package options. Ambient operating temperature range
is -40ºC to +85ºC. For further information, visit the Company’s website at
