VCUT0505B-HD1

ESD-Protection Diode in LLP1006-2L

CUT THE SPIKES WITH VCUT0505B-HD1:

The VCUT0505B-HD1 is a Bidirectional and Symmetrical (BiSy) ESD-protection device which clamps positive and negative

overvoltage transients to ground. Connected between the signal or data line and the ground the VCUT0505B-HD1 offers a high

isolation (low leakage current, low capacitance) within the specified working range. Due to the short leads and small package

size of the tiny LLP1006-2L package the line inductance is very low, so that fast transients like an ESD-strike can be clamped

with minimal over- or undershoots.
