EClamp0504T Low Profile EClampTM 4-Line ESD protection PROTECTION PRODUCTS - EMIClampTM Description Features The EClamp 0504T is designed to protect sensitive electronics from damage or latch-up due to ESD. This stateof-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. It has been optimized for protection of digital lines in cellular phones and other portable electronics. TM Transient protection for data lines to The device replaces up to eight discrete components in a small footprint. It consists of a TVS diode and a series 1K Ohm resistor on each line. The TVS diode presents a maximum loading capacitance of 15pF for maximum signal integrity. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 61000-4-2, level 4. IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) Cable Discharge Event (CDE) Protects four data lines TVS working voltage: 5V Series Resistor: 1K Ohm Capacitance: 15pF (Maximum at VR = 0V) Low leakage current (<100nA) Solid-state silicon-avalanche technology Mechanical Characteristics The EClampTM0504T is in a 8-pin, RoHS compliant, SLP2116P8T package. It measures 2.1 x 1.6 x 0.40mm. The leads are spaced at a pitch of 0.5mm and are finished with lead-free NiPdAu. Each device will protect four lines operating at 5 volts. It gives the designer the flexibility to protect single lines in applications where arrays are not practical. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.

The device is unidirectional and may be used on lines where the signal polarity is above ground. 1K Ω In Circuit Board Layout Recommendations for Suppression of ESD. 15pF Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: z Place the TVS near the input terminals or connectors to restrict transient coupling. z Minimize the path length between the TVS and the protected line. z Minimize all conductive loops including power and ground loops. z The ESD transient return path to ground should be kept as short as possible. z Never run critical signals near board edges. z Use ground planes whenever possible. © 2009 Semtech Corp.
