UM1002
Dual Channel ESD Protection Device
UM1002 SOT23-6
General Description
The UM1002 is a low pass filter array with integrated TVS diodes for ESD protection. It is designed
to provide bidirectional filtering of EMI/ RFI signals and electrostatic discharge (ESD) protection in
portable electronic equipment. This state-of-the art device utilizes solid-state silicon-avalanche
technology for superior clamping performance and DC electrical characteristics. They have been
optimized for use on a USB port in cellular phone and other portable electronics.
The UM1002 effectively replaces 10 discrete components in a small SOT23-6 package to provide
ESD protection and EMI filtering. This small package will protect and filter up to two lines. This
small outline makes the device especially well suited for portable applications.
The TVS diodes are bi-directional for supporting bipolar signals without distortion. The TVS diodes
provide effective suppression of ESD voltages in excess of 15kV (air discharge) and 8kV (contact
discharge) per IEC61000-4-2, level 4.The device has very low insertion loss in the pass band (to
approximately 10MHz) and high attenuation at frequencies ranging from 800MHz to 3GHz. Each line
features two stages of TVS diode protection. They feature large cross-sectional area junctions for
conducting high transient currents. They offer desirable characteristics for board level protection
including fast response time, low operating and clamping voltage, and no device degradation.
