PESDSC2FD5VB

PESDSC2FD5VB Bi-directional 5V Low Capacitance ESD Protector Description The PESDSC2FD5VB 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  80W 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 Pin 1 Pin 2 Circuit Diagram IEC61000-4-2(ESD) ±15KV(air), ±8KV(contact); IEC61000-4-4 (EFT) 40A (5/50ns) Applications  Cellular phones  Portable devices  Digital cameras  Power supplies B1 Marking (Top View) Mechanical Characteristics  Mounting position: Any  Qualified max reflow temperature:260℃  Device meets MSL 1 requirements  DFN1006-2L without plating Rev.06.6 1 www.prisemi.com ESD Protector PESDSC2FD5VB Electronics Parameter Symbol VRWM IR VBR Parameter Peak Reverse Working Voltage Reverse Leakage Current @ VRWM IPP 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 Electrical characteristics per line@25℃ (unless otherwise specified) Parameter Peak Reverse Working Voltage Breakdown Voltage Symbol Conditions Min.

PCB Design For TVS diodes a low-ohmic and low-inductive path to chassis earth is absolutely mandatory in order to achieve good ESD protection. 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.
