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.
uClamp5591P is in a DFN 1.0x0.6x0.50mm 2-Lead package.
Each device may be used to meet the ESD immunity
requirements of IEC 61000-4-2 (±20kV air, ±20kV contact
discharge). uClamp5591P 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.
