ESD PROTECTION DEVICE
DESCRIPTION
The UTC UTVS2200 utilizes innovative Super Surge Control
technology to introduce transient diverting suppressors (TDS) for
protecting systems from EOS and ESD events. This robust surge
solution utilizes integrated circuit technology. Instead of relying on
the breakdown and current dissipation of the PN junction in
traditional TVS diodes, the TDS diverts the surge current to
ground via a built-in surge-rated field-effect transistor (FET),
which has a lower on-resistance than the PN junction in TVS
diodes. As a result, the TDS device provides a precise, flat, and
temperature-independent clamping voltage, minimizing residual
voltage in the protected system.
The UTC UTVS2200 is ideal for protecting power buses
operating up to 22V and is rated for transient peak pulse currents
up to 70A (tp = 8/20μs). Housed in a compact DFN2020-6L
package, the TDS is 90% smaller than the industry-standard
SMA/SMB package, offers lower capacitance, and 50% lower
leakage current than traditional TVS-based solutions.
