UCLAMP3301H datasheet



The μClampTM series of Transient Voltage Suppressors (TVS) are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDAs. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. They are designed to protect sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE).


1. Transient protection for data lines to
IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact)
IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)
Cable Discharge Event (CDE)

2. Small SOD-523 package

3. Protects one data line

4. Low clamping voltage

5. Working voltage: 3.3V

6. Low leakage current

7. Solid-state silicon-avalanche technology
