PTVSLC3D8VB

PTVSLC3D8VB Low Capacitance TVS Description The PTVSLC3D8VB is a low capacitance transient voltage suppressor for high speed data interface that designed to protect sensitive electronics from damage or latch-up due to ESD lightning, and other voltage induced transient events. All pins are rated to withstand 15kV ESD pulses using the IEC61000-4-2 air discharge method, which can meet the requirement of level 4. Applications Feature  350W peak pulse power per line (tP = 8/20μs)  Ethernet – 10/100/1000 Base T  SOD-323 package  Cellular phones  Replacement for MLV(0805)  Handheld-wireless systems  Bidirectional configurations  PDAs  Protects one power or I/O port  USB interface  Low clamping voltage  RoHS compliant  Transient protection for data lines to IEC61000-4-2(ESD) ±30kV(air), ±30kV(contact); IEC61000-4-4 (EFT) 80A (5/50ns) Mechanical Characteristics  Lead finish:100% matte Sn(Tin)  Mounting position: Any  Qualified max reflow temperature:260℃  Pure tin plating: 7 ~ 17 um  Pin flatness:≤3mil Electronics Parameter Symbol VRWM IR VBR Rev.06.2 Parameter Peak Reverse Working Voltage IPP Reverse Leakage Current @ VRWM I Breakdown Voltage @ IT IT Test Current IPP Maximum Reverse Peak Pulse Current VC Clamping Voltage @ IPP PPP Peak Pulse Power CJ Junction Capacitance IF Forward Current VF Forward Voltage @ IF VC VBR VRWM IT IR V IR IT VRWM VBR VC IPP 1 www.prisemi.com Low Capacitance TVS PTVSLC3D8VB Electrical characteristics per line@25℃( unless otherwise specified) Parameter Symbol Peak Reverse Working Voltage Conditions Min.

Novices in the area of ESD protection should take following suggestions to heart:  Do not use stubs, but place the cathode of the TVS diode directly on the signal trace.  Do not make false economies and save copper for the ground connection.  Place via holes to ground as close as possible to the anode of the TVS diode.  Use as many via holes as possible for the ground connection.  Keep the length of via holes in mind! The longer the more inductance they will have.
