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.
