TPESDS552DBZR

Component

Bidirectional TVSRS-485 protectionRS-422 protectionSOT-23±30 kV ESD15 pF

TPESDS552DBZR is a bidirectional, two-line TVS array for protecting RS-485 and RS-422 differential interfaces from ESD and surge events.

Best for

  • RS-485 differential bus interfaces
  • RS-422 communication ports
  • Connector-side ESD protection

Avoid if

  • The protected circuit cannot tolerate up to 23.5 V clamping during a 20 A surge
  • Formal compliance or lifecycle documentation is mandatory but unavailable

Check before use

  • Confirm the 12 V working-voltage range matches the line voltage
  • Check clamping voltage against the protected IC ratings
  • Use a low-inductance ground connection
  • Verify the SOT-23 land pattern and pin assignment
