SP3312T Series TVS Diode Array (SPA® Diodes)
What Is It? / What Does It Do?
TVS Diode Arrays (SPA® Diodes), commonly called Diode Arrays, are a family of
discrete diodes and diode arrays designed to protect sensitive electronic equipment
against destructive electrostatic discharges (ESD) and lightning-induced surge currents.
Why use this product?
The SP3312T integrates four channels (two differential
pairs) of low capacitance diodes to protect sensitive I/O
pins from damage due to lightning-induced surge events
and ESD. This robust device can safely absorb up to 15A
per IEC 61000-4-5 (tp=8/20μs) without performance
degradation and a minimum ±30kV ESD per IEC 610004-2 international standard. The low loading capacitance
makes the SP3312T ideal for protecting high-speed
signal pins.

Benefits
 Compared to similar market solutions, the
 Negligible variability in capacitance
 Improved signal integrity of the lines the
SP3312T Series offers far more overhead to
electrical threats as defined by regulatory
standards
– Peak pulse power 250W
over operating voltage range
device is protecting, less eye diagram
degradation vs. competing solutions
– 0.3pF typical (VR=0 to 2.5V)
 15A peak current ESD protection
 Allows manufacturers to claim ESD protection
– ESD, IEC 61000-4-2, ±30kV contact,
±30kV air discharge
– EFT, IEC 61000-4-4, 40A
– Lightning, IEC 61000-4-5, 15A
above the maximum level stated in the IEC
standard and protects against a multitude of
other threats to ensure product reliability in
the field
 Small form factor µDFN-08 package  Allows the PCB trace to be routed underneath
(1.8x2.0x0.554mm) allows straightthrough routing
the device without the need for stub traces
that can cause signal degradation

Littelfuse Key Advantages
•
Excellent Power Handling 250W
– Compared to similar market solutions, the
SP3312T Series provides remarkably more
overhead to electrical threats defined by
regulatory standards
150% more power handling capability for the
SP3312T
•
•
•
Negligible variability in capacitance over
operating voltage range
− 71% higher than other solutions helps to
preserve signal integrity and minimize data
loss while offering a more robust device
against electrical threats
Small form factor µDFN-08 package
(1.8x2.0x0.4 mm) simplifies the PCB layout by
allowing the traces to run directly underneath the
device without the need for stub traces that can
cause signal degradation
SP3312TUTG
Automotive-grade quality ensures maximum
reliability in the harshest environments
