UCLAMP1211P
UCLAMP1211P is 1-Line ESD protection manufactured by SEMTECH.
µClamp TM .. 1-Line ESD protection
PROTECTION PRODUCTS
- Micro Clamp TM Description
The µClamp series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. It is designed to replace multilayer varistors (MLVs) in portable applications. It Features large crosssectional area junctions for conducting high transient currents. It offers superior electrical characteristics such as lower clamping voltage and no device degradation when pared to MLVs. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.

Features
Transient protection for data lines to
IEC 61000-4-2 (ESD) ±15k V (air), ±8k V (contact) IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) Cable Discharge Event (CDE) Ultra-small package (1.0 x 0.6 x 0.5mm) Protects one I/O or power line Low clamping voltage Working voltage: ±12V Low leakage current Solid-state silicon-avalanche technology
Mechanical Characteristics
The µClamp 1211P is in a 2-pin, Ro HS/WEEE pliant, SLP1006P2 package. It measures 1.0 x 0.6 x 0.5mm. The leads are spaced at a pitch of 0.65mm and are finished with lead-free Ni Pd Au. Each device will protect one bidirectional line operating at ±12 volts. It gives the designer the flexibility to protect single lines 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). The bination of small size and high ESD surge capability makes them ideal for use in portable applications such as cellular phones, digital cameras, and MP3 players.
