5−Line Transient Voltage
Suppressor Array
This 5−line voltage transient suppressor array is designed for
application requiring transient voltage protection capability. It is
intended for use in over−transient voltage and ESD sensitive
equipment such as computers, printers, automotive electronics,
networking communication and other applications. This device
features a monolithic common anode design which protects five
independent lines in a single SC−74 package.
Features
• Protects up to 5 Lines in a Single SC−74 Package
• Peak Power Dissipation − 350 W (8 20 s Waveform)
• ESD Rating of Class 3B (Exceeding 8.0 kV) per Human Body Model
and Class C (Exceeding 400 V) per Machine Model
• Compliance with IEC 61000−4−2 (ESD) 15 kV (Air), 8.0 kV
(Contact)
• Flammability Rating of UL 94 V−0
• Pb−Free Package is Available
Applications
• Hand−Held Portable Applications
• Networking and Telecom
• Automotive Electronics
• Serial and Parallel Ports
• Notebooks, Desktops, Servers

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

2. TVS devices are normally selected according to the working peak reverse voltage (V
RWM
), which should be equal or greater than the DC
or continuous peak operating voltage level.
3. V
BR
is measured at pulse test current I
T
.
4. Parametrics are the same for the Pb−Free packages, which are suffixed with a “G’’.
