PTVSHC2EN4V5B
Transient Voltage Suppressor
Description
The PTVSHC2EN4V5B ESD protector 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 PTVSHC2EN4V5B protects sensitive semiconductor components from
damage or upset due to electrostatic discharge (ESD) and other voltage induced transient
events. The PTVSHC2EN4V5B is available in a DFN1610-2L package with working
voltages of 4.5 volt. It is used to meet the ESD immunity requirements of IEC 61000-4-2,
(±30kV air, ±30kV contact discharge)

Note 1: VRWM is the maximum reverse working voltage, or reverse stand-off voltage. ESD can protect signal line properly
within its rated voltage. If the signal line's voltage is over VRWM, ESD will change to other state.

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.
