| ESDALC6V1Px Low capacitance TransilTM arrays for ESD protection Features 2 to 4 unidirectional Transil functions Breakdown voltage VBR = 6.1 V min. Low leakage current < 100 nA Low capacitance (7.5 pF @ 3 V) Very small PCB area < 2.6 mm2 Figure 1. ESDALC6V1P3 functional diagram SOT-663 SOT-665 SOT-666IP Benefits High ESD protection level High integration Complies with the following standards IEC61000-4-2 level 4 - 15 kV (air discharge) - 8 kV (contact discharge) MIL STD 883E-Method 3015-7: class3 - 25 kV HBM (human body model) Figure 2. ESDALC6V1P5 functional diagram Applications Where transient overvoltage protection in ESD sensitive equipment is required, such as: Computers Printers Communication systems Cellular phone handsets and acessories Wireline and wireless telephone sets Set-top boxes Figure 3. ESDALC6V1P6 functional diagram Description The ESDALC6V1Px are monolithic suppressors designed to protect components connected to data and transmission lines against ESD. These devices clamp the voltage just above the logic level supply for positive transients and to a diode drop below ground for negative transients.
