3 Description
The ESDS452 is a bidirectional ESD and TVS diode.
The ESDS452 is rated to dissipate ESD strikes
beyond the maximum level specified in the IEC
61000-4-2 international standard (±30kV Contact,
±30kV Air-gap). The device can clamp 8/20μs surges
with peak pulse currents up to 18A in accordance
with the IEC 61000-4-5 standard. Additionally, the low
clamping voltage of the diodes in both the positive
and negative directions can help prevent downstream
circuitry from being exposed to large voltages and
currents during ESD or surge events. This protection
is key in industrial systems which require a high level
of robustness and reliability.
The ESDS452 is available in a small leaded SOT-23
(DBZ) package.
