Texas Instruments ESDS552 Bi-Directional ESD/Surge Protection Diode
Texas Instruments ESDS552 Bi-Directional ESD/Surge Protection Diode is for RS-485 and RS-422 interface protection. The ESDS552 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 25A in accordance with the IEC 61000-4-5 standard.
The low clamping voltage and low dynamic resistance help protect systems against transient events. This protection is critical because industrial systems require a high level of robustness and reliability. The Texas Instruments ESDS552 is available in a small leaded SOT-23 (DBZ) package.
