ESDS552
- IEC 61000-4-5 surge protection:
- 25A (8/20µs)
- IEC 61000-4-2 ESD protection:
- ±30kV contact discharge
- ±30kV air gap discharge
- 12V working voltage
- Bidirectional polarity to support positive and negative voltage swings
- 2 channel device provides complete ESD/Surge protection with single component
- Small, leaded SOT-23 allows low cost automatic optical inspection (AOI)
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.
