PESDWC2FD5VB

PESDWC2FD5VB ESD Protector Description The PESDWC2FD5VB protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. They feature large cross-sectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, low operating voltage. It gives designer the flexibility to protect one bi-directional line in applications where arrays are not practical. Applications Feature  80W peak pulse power per line (tP = 8/20μs)  Cellular phones  DFN1006-2L package  Portable devices  Replacement for MLV(0402)  Digital cameras  Bidirectional configurations  Power supplies  Response time is typically < 1ns  High ESD protection  Low clamping voltage  RoHS compliant  Transient protection for data lines to IEC61000-4-2(ESD) ±15KV(air), ±8KV(contact) Mechanical Characteristics  Lead finish:100% matte Sn(Tin)  Mounting position: Any  Qualified max reflow temperature:260℃  Device meets MSL 1 requirements  Pure tin plating: 7 ~ 17 um  Pin flatness:≤3mil Electronics Parameter Symbol Parameter VRWM Peak Reverse Working Voltage IR Reverse Leakage Current @ VRWM VBR 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 Rev.06.4 IPP VC VBR VRWM I IT IR V IR IT VRWM VBR VC IPP 1 www.prisemi.com ESD Protector PESDWC2FD5VB Electrical characteristics per line@25℃ (unless otherwise specified) Parameter Symbol Conditions Peak Reverse Working Voltage VRWM Breakdown Voltage VBR It = 1mA Reverse Leakage Current IR Clamping Voltage Max.

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.
