STE0521  1 -Line TVS Diode (Bidirectional)

The STE0521 are designed by TVS bi-direction device that is to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space ia at a premium.
STE0521 will protect single line, and may be used on lines where the signal polarities swing above and below ground.
HGE0521 offer desirable acaracteristics for board level protection including fast response time, low operating and clamping voltage and no device degradation.
HGE0521 may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SOD-523 package makes them ideal for use in portable electronics such as cell phone, PDA’s, notebook computers, digital cameras and MP3.
