Circuit Protection

TVS diode arrayBidirectionalAutomotiveAEC-Q101SOT-23-3ESD protection

ESDS452DBZRQ1 is a two-channel automotive bidirectional TVS array for protecting ±5.5 V signal lines against high-level ESD and 8/20 µs surge events.

Best for

  • Automotive bidirectional signal-line protection
  • Low-capacitance ESD protection
  • BMS communication and sensing interfaces

Avoid if

  • Continuous line voltage exceeds ±5.5 V
  • The downstream circuit cannot tolerate the specified clamp level
  • A single unidirectional protection path is required

Check before use

  • Verify actual surge waveform and current against the 18 A, 8/20 µs rating.
  • Use a short, wide, low-inductance ground connection.
  • Confirm channel assignment and package orientation.
