3 Description

The ESDS452-Q1 is a bidirectional ESD and TVS

diode. The ESDS452-Q1 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 as automotive systems require a high level

of robustness and reliability when controlling safety

devices.

The ESDS452-Q1 is available in a small leaded

SOT-23 (DBZ) package.
