SPE1244

SPE1244 3-Line ESD Protection Array DESCRIPTION The SPE1244 are designed by TVS array that is to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space is at a premium. SPE1244 will protect up to three line, and may be used on lines where the signal polarities swing above and below ground. SPE1244 offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. SPE1244 may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SOT-143 package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras.
