UT3115B
Bidirectional Transient Voltage Suppressor (TVS)
General Description Features
The UT3115B is a bidirectional Transient Voltage ESD Protection for the protected line to:
Suppressor (TVS) designed to protect 5.0V circuits IEC 61000-4-2(ESD): ± 30 kV (Contact)
from transient events such as high Electrostatic
IEC 61000-4-2(ESD): ± 30 kV (Air)
Discharge (ESD) and Cable Discharge Event
(CDE). IEC 61000-4-4(EFT): 100A
IEC 61000-4-5(Surge): 13A (8/20μs)
This TVS uses a proprietary cell clamping
Junction Capacitance (Pin1 to Pin 2): 14pF
technology. During transient events, these cells
clamp transient over-voltages on power or control Operating Voltage: 5.0 V
data signals to protect sensitive circuitry. SOD523-2L (1.2mm X 0.8mm X 0.64mm )
The UT3115B is an ideal solution for high speed Pb-Free/Halogen Free/BFR Free and RoHS
data line applications. Compliant
