Low Voltage µClamp TM for ESD and CDE Protection
PROTECTION PRODUCTS
- Micro Clamp TM Description
The µClamp series of Transient Voltage Suppressors (TVS) are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook puters, and PDAs. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when pared to MLVs. They are designed to protect sensitive semiconductor ponents from damage or upset due to electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE). The µclamp TM3301H is constructed using Semtech’s proprietary EPD process technology. The EPD process provides low standoff voltages with significant reductions in leakage currents and capacitance over siliconavalanche diode processes. They feature a true operating voltage of 3.3 volts for superior protection when pared to traditional pn junction devices. The µclamp3301H is in a SOD-523 package and will protect one unidirectional line. They give the designer the flexibility to protect one line in applications where arrays are not practical. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15k V air, 8k V contact discharge).
