SMBJXXA Series ESD Protection Diodes

Semtech SMBJXXA Series 1-line ESD protection diodes feature large cross-sectional area junctions for conducting high transient currents

Image of Semtech SMBJXXA Series ESD Protection DiodesSemtech SMBJXXA series diodes protect sensitive electronics from damage or latch-up due to EOS, lightning, CDE and ESD. These diodes feature large cross-sectional area junctions for conducting high transient currents. Board level protection includes fast response time, low operating and clamping voltage, and no device degradation.

Engineered to safeguard sensitive electronic circuits against destructive transient voltage events, SMBJXXA TVS diodes deliver reliable protection for critical applications.
