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.
