PLANO, Texas -- October 15, 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 pair of
high-sensitivity, micropower devices, extending its family of Hall effect
switches. Bringing greater design flexibility and savings in both power and
space, the AH1902 and AH1903 help raise the performance bar of a wide range of
contact-less switch applications in consumer, domestic, office and industrial
products.

The AH1902 is an omnipolar device, detecting both north and south magnetic
fields. In default mode, the programmable AH1903 operates as a unipolar
device, detecting a south pole at the part-marked package surface. The device
also offers an omnipolar mode, enabling it to meet the needs of multiple
applications and to be changed ‘on the fly’ in the event of a field direction
issue. The AH1903 function is changed using a simple select pin, driven by an
external logic source or microcontroller.

The high sensitivity of both switches means weaker magnets can be employed or
detection distances extended; the switches’ typical operating threshold switch
point is ±35G.

Designed to be used with a low voltage supply, these latest Hall switches from
Diodes Incorporated operate over the 1.6V to 3.6V voltage range. This
characteristic, coupled with an integral sleep function and a typical current
consumption of 4.3µA, makes them well-suited for battery-powered applications.

To aid product miniaturization, the switches are provided in a variety of
space-saving, low-profile, surface-mount packages. The omnipolar AH1902 comes
in the DFN1216-4, the ultra-thin DFN2015-6 and SOT553 packages. The AH1903 is
available in the 1.2x1.6x0.5mm DFN1216-4 package, making it the industry’s
smallest omnipolar/unipolar programmable Hall switch.

To accommodate a wide range of hand-held applications, these high-reliability
switches have an 8kV electrostatic discharge withstand capability and offer
good immunity to RF noise and other circuit stresses. Operating and release
points are also highly stable over the -40ºC to +85ºC temperature range, and
with a very low temperature coefficient, the switches are immune to early or
late switching. For further information, visit the Company’s website at
