SOT-23 (DBZ)-3-6.9204 mm² 2.92 x 2.37
The ESDS552 is a bidirectional ESD and surge protection diode 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 dynamic resistance and low clamping voltage help protect systems against transient events. This protection is key because industrial systems require a high level of robustness and reliability.
The ESDS552 is available in a small leaded SOT-23 (DBZ) package.
