SM1KxxCF Series Transient Voltage Suppressor

FEATURES:

 Excellent clamping capability.

 Low profile package and low inductance.

SMBF

 High peak pulse voltage capability on 1.2/50μs-8/20μs@2Ω waveform.

 Fast response time: typically less than 1.0ps from 0V to V_BRmin.

 High temperature soldering: 260℃/40s at terminals.

 Plastic package has underwriters laboratory flammability 94V-0.

 For surface mounted applications in order to optimize board space.
