Description

The SRV05 integrates low capacitance rail-to-rail diodes with
an additional zener diode to protect each I/O pin against
ESD and high surge events. This robust device can safely
absorb surge current per IEC61000-4-5 (t

=8/20µs) without

P

performance degradation and a minimum ±20kV ESD
per IEC61000-4-2. Their very low loading capacitance also
makes them ideal for protecting high speed signal pins.

Features

• ESD, IEC61000-4-2,
±20kV contact, ±30kV air

• EFT, IEC61000-4-4, 40A

(5/50ns)

• Lightning, IEC61000-4-5,
10A (8/20μs)

• Low capacitance of 2pF

(TYP) per I/O

• Low leakage current of

0.5μA (MAX) at 5V

• Small SOT23-6 (

MO-178) packaging

JEDEC

Applications

• LCD/PDP TVs

• Monitors

• Notebooks

• 10/100/1000 Ethernet

• Firewire

• Set Top Boxes

• Flat Panel Displays
