Description
μClamp® series of TVS diodes are designed 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.
uClamp04091P is in a DFN 1.00 x 0.60 x 0.50mm 2-Lead
package. Each device may be used to meet the ESD
immunity requirements of IEC 61000-4-2 (±20kV air, ±20kV
contact discharge). uClamp04091P also provides high
surge current capability (20A, tp=8/20μs). The combination
of small size and high ESD and surge capability makes them
ideal for use in applications such as portables, wearables
and various industrial equipment.
