PESD3V3L1BA — SOD323 Package

Notes

• Package: SOD323 (SC-76); 2-lead surface-mounted package
• Function: Bidirectional ESD protection diode. Both pins (K1 and K2) serve as the protected signal line; the device provides bidirectional clamping for transient suppression.
• Key Ratings:
  • Max peak pulse power: 500 W (8/20 μs pulse)
  • Max peak pulse current: 18 A
  • ESD protection: up to 30 kV (IEC 61000-4-2 contact discharge)
  • Low clamping voltage: 26 V @ 18 A
  • Ultra-low leakage: 0.09 μA typical @ 3.3 V
  • Diode capacitance: 101 pF typical @ 1 MHz

The device is designed for the protection of one bidirectional data line from surge pulses and ESD damage. The device is suitable on lines where the signal polarities are both positive and negative with respect to ground.
