ESD5432E 2-lines, bi-directional, transient voltage suppressors descriptions the ESD5432E is a 2-lines bi-directional tvs (transient voltage suppressor). it is specifically designed to protect sensitive electronic components which are connected to power lines, low speed data lines and control lines from over-stress caused by esd (electrostatic discharge), eft (electrical fast transients) and lightning. the ESD5432E may be used to provide esd protection up to 30kv (contact discharge) according to iec61000-4-2, and withstand peak pulse current up to 10a (8/20 s) according to iec61000-4-5. the ESD5432E is available in sot-23 package. standard products are pb-free and halogen-free. features ? stand-off voltage: 3.3v max ? transient protection for each line according to iec61000-4-2 (esd): 30kv (contact discharge) iec61000-4-4 (eft): 40a (5/50ns) iec61000-4-5 (surge): 10a (8/20 s) ? capacitance: c j = 17.5pf typ. ? low leakage current: i r = 1na typ. ? low clamping voltage: v cl = 8v typ. @ i pp = 16a (tlp) ? solid-state silicon technology applications ? cellular handsets ? computers and peripherals ? microprocessors ? power lines ? portable electronics ? notebooks sot-23 circuit diagram 1 = device code * = month code ( a~z) marking (top view) order information device package shipping ESD5432E-3/tr sot-23 3000/tape&reel gnd 2 3 i/o1 i/o2 e * 1 1 of 6 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification
