PESDMC2FD5VB

PESDMC2FD5VB Bi-directional 5V Low Capacitance ESD Protector Description The PESDMC2FD5VB 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 DFN1006-2L(Bottom View) line in applications where arrays are not practical. Feature  40W peak pulse power per line (tP = 8/20μs)  DFN1006-2L package  Replacement for MLV(0402)  Bidirectional configurations  Response time is typically < 1ns  Low clamping voltage  RoHS compliant  Transient protection for data lines to B1 Marking (Top View) IEC61000-4-2(ESD) ±15KV(air), ±15KV(contact); IEC61000-4-4 (EFT) 40A (5/50ns) Applications  Cellular phones  Portable devices  Digital cameras  Power supplies Pin 1 Pin 2 Circuit Diagram Mechanical Characteristics  Lead finish:100% matte Sn(Tin)  Mounting position: Any  Qualified max reflow temperature:260℃  Device meets MSL 1 requirements Rev.06.3 1 www.prisemi.com ESD Protector PESDMC2FD5VB Electronics Parameter Symbol VRWM IR VBR Parameter Peak Reverse Working Voltage I Reverse Leakage Current @ VRWM IPP 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 VHOLD VTRIG VRWM IT IR IR IT VRWM VC VTRIG VHOLD V IPP Electrical characteristics per line@25℃ (unless otherwise specified) Parameter Symbol 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.
