TClamp1202P Low Capacitance TClamp Surge Protection for 12V Interfaces PROTECTION PRODUCTS Description Features Transient protection for high-speed data lines to TClamp1202P provides dedicated surge and ESD IEC 61000-4-2 (ESD) 20kV (air), 15kV (contact) protection for RS-485 and other 12V lines in industrial IEC 61000-4-4 (EFT) 40A (5/50ns) applications. It features high surge current capability IEC 61000-4-5 (Lightning) 100A (8/20s) of 100A (tp=8/20 s) and low clamping voltage making Array of surge rated diodes with internal TVS Diode them ideal for use in harsh transient environments. Protects up to two lines Low capacitance: (<12pF) Operating voltage: 12V This device is designed to replace mulitple discrete Low leakage current components by integrating low capacitance, surgerated Solid-state silicon-avalanche technology compensation diodes with a high power transient voltage suppressor (TVS). Capacitance is limited to Mechanical Characteristics 12pF maximum to ensure correct signal transmission on high-speed lines. Each TClamp1202P may be used SLP2020P5 Package to protect up to two lines. A voltage bus operating up Pb-Free, Halogen Free, RoHS/WEEE Compliant to 12V can also be optionally protected. Lead Finish: NiPdAu Molding Compound Flammability Rating: UL 94V-0 Marking : Marking code + Date Code The TClamp1202P is in a 5-pin SLP2020P5 package, Packaging : Tape and Reel measuring 2.0 x 2.0mm with a nominal height of 0.60mm. The flow- through package design simplifies Applications PCB layout.
