SLVU2.8Q Low Voltage TVS Diode for Automotive Applications PROTECTION PRODUCTS Features Description The SLVU2.8Q transient voltage suppressor is rated to 400 Watts peak pulse power (t = 8/20 s) p Grade 3 of AEC-Q100 for use in automotive applica- Transient protection for high speed data lines to tions. It is specifically designed to protect sensitive IEC 61000-4-2 (ESD) 30kV (air), 25kV (contact) components which are connected to data and trans- IEC 61000-4-4 (EFT) 40A (5/50ns) mission lines from overvoltage events. It may be used IEC 61000-4-5 (Lightning) 24A (8/20 s) to protect one single ended line operating up to 2.8 One device protects one unidirectional line Volts. Qualified to AEC-Q100, Grade 3 The SLVU2.8Q is constructed using Semtechs propri- Low leakage current etary EPD process technology. The EPD process Low operating and clamping voltages provides a true low operating voltage of 2.8 Volts for Solid-state silicon-avalanche technology maximum circuit protection. The SLVU2.8Q features Mechanical Characteristics high ESD capability (+/-25kV contact, +/-30kV air per IEC 61000-4-2), low clamping voltage, and is rated to JEDEC SOT-23 3L package absorb up to 24A for an 8/20us duration pulse. Since Pb-Free, Halogen Free, RoHS/WEEE Compliant the SLVU2.8Q is constructed using solid-state silicon- Molding compound flammability rating: UL 94V-0 avalanche technology, it will not degrade as long as it is Marking: Marking Code operated within data sheet parameters. Packaging: Tape and Reel The SLVU2.8Q is in a 3-lead SOT23 package. The Applications leads are finished with matte tin. This device is a Pb- Free, Halogen Free, RoHS/WEEE compliant product.
