PTVSHC1TF24VBH
Bi-directional 24V High Capacitance TVS Protector
Description
The PTVSHC1TF24VBH 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
PTVSHC1TF24VBH
protects
sensitive
semiconductor components from damage or upset due to electrostatic
discharge (ESD) and other voltage induced transient events. The
PTVSHC1TF24VBH is available in a SOD-123FL package with working
voltages of 24 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.
