PTVSHC3N10VU
Uni-directional 10V High Capacitance TVS
Description
The PTVSHC3N10VU Transient Voltage Suppressor is designed to replace
multilayer varistors (MLVs) in portable applications such as cell phones,
notebook computers, and PDA’s. 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, lower
operating voltage, lower clamping voltage and no device degradation when
compared to MLVs. The PTVSHC3N10VU protects sensitive semiconductor
components from damage or upset due to electrostatic discharge (ESD) and
other voltage induced transient events. The PTVSHC3N10VU is available in a
DFN2×2-3L package with working voltages of 10 volt.

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.
