PESDNC2FD5VBH
Bi-directional 5V Normal Capacitance ESD Protector
Description
The PESDNC2FD5VBH 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.

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.
