PESDLC2FD3V3BH

PESDLC2FD3V3BH Bi-directional 3.3V Low Capacitance ESD Protector Description The PESDLC2FD3V3BH 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 DFN1006-2L(Bottom View) designer the flexibility to protect one bi-directional line in applications where arrays are not practical.

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.
