uClamp3311PQ Low Voltage Clamp for Automotive Applications PROTECTION PRODUCTS PROTECTION PRODUCTS - MicroClamp Features Description The Clamp 3311PQ transient voltage suppressor is Transient protection for data lines to specifically designed to protect sensitive components IEC 61000-4-2 (ESD) 25kV (air), 20kV (contact) which are connected to low-voltage data and transmis- IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) sion lines from overvoltage caused by ESD (electro- Cable Discharge Event (CDE) static discharge), CDE (cable discharge events), and Qualified to AEC-Q100, Grade 3 EFT (electrical fast transients). It is rated to Grade 3 Protects one data line of AEC-Q100 for use in automotive applications. Low clamping voltage The Clamp 3311PQ is constructed using Semtechs Working voltage: 3.3V proprietary EPD process technology. The EPD process Low leakage current provides low standoff voltages with significant reduc- Solid-state silicon-avalanche technology tions in leakage currents and capacitance over silicon- avalanche diode processes. They feature a true Mechanical Characteristics operating voltage of 3.3 volts for superior protection SLP1006P2 package when compared to traditional pn junction devices. Pb-Free, Halogen Free, RoHS/WEEE Compliant The Clamp3311PQ is in an 2-pin SLP1006P2 pack- Nominal Dimensions: 1.0 x 0.6 x 0.5 mm age. It measures 1.0 x 0.6 x 0.5mm. The leads are Lead Finish: NiPdAu spaced at a pitch of 0.65mm and are finished with Molding compound flammability rating: UL 94V-0 lead-free NiPdAu. Each device will protect one line Marking : Marking code operating at 3.3 volts. It gives the designer the flexibil- Packaging : Tape and Reel ity to protect single lines in applications where arrays are not practical. They may be used to meet the ESD Applications immunity requirements of IEC 61000-4-2. The combi- Automotive Applications nation of low voltage, small size and high ESD surge capability makes them ideal for protection of sensitive Low Voltage Data Lines electronics in automotive applications. 10/100 Ethernet Dimensions Schematic & PIN Configuration 1.0 0.60 0.65 0.50 Maximum Dimensions (mm) SLP1006P2 (Bottom View) www.semtech.com Revision 7/282011 1uClamp3311PQ PROTECTION PRODUCTS Absolute Maximum Rating Rlating Seymbo Vsalu Unit PPeak Pulse Power (tp = 8/20s) 9s0 Watt pk M)aximum Peak Pulse Current (tIp = 8/20s 5sAmp pp ESD per IEC 61000-4-2 (Air) V +/- 25 kV ESD ESD per IEC 61000-4-2 (Contact) +/- 20 OTperating Temperature -C40 to +85 J STtorage Temperature -C55 to +150 STG o Electrical Characteristics (T=25 C) Plarameter SsymboCmondition MlinimuTmypicaMsaximu Unit RVeverse Stand-Off Voltage 3V.3 RWM PVunch-Through Voltage I=52A, T=25C3V.
