Description

The SMF series TVS arrays, including the SMF05C.TR model, are electronic components that serve to protect sensitive electronics from potential damage or latch-up caused by electrostatic discharge (ESD) and other voltage-induced transient events. These components are specifically designed for applications where board space is limited. Each device in the series can protect up to five lines and is suitable for use on lines with signal polarities above ground.

Specifications and features

The SMF05C.TR features the following specifications and features:

• ESD protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
• IEC 61000-4-4 (EFT) 40A (5/50ns)
• Small package designed for portable electronics
• Protects five I/O lines
• Working voltage: 5V
• Low leakage current
• Low operating and clamping voltages
• Solid-state silicon-avalanche technology

Application Scenarios

The SMF05C.TR model is commonly used in the following application scenarios:

• Cellular Handsets and Accessories
• Cordless Phones
• Personal Digital Assistants (PDA’s)
• Notebooks and Handhelds
• Portable Instrumentation
• Digital Cameras
• Peripherals
• MP3 Players
