Semtech PClamp1221P
Ultra Small PowerClamp® 1-Line ESD & Surge Protection

PowerClamp TVS diodes are designed for use in harsh transient environments to protect sensitive electronics from damage or latch-up due to EOS, lightning, CDE, and ESD. They feature large cross-sectional area junctions for conducting high transient currents. These devices offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.
