Application Scenarios & Design Considerations

Transient Voltage Suppressors

Alternative Part Number

  • SRV05-4 --: Same manufacturer's low-capacitance TVS diode array in a similar package, commonly used as a drop-in protection alternative for SMDB03.
  • USBLC6-2SC6 --: Widely available ESD protection array with comparable clamping performance and pinout, suitable for data-line protection applications.
  • TPD4E05U06 --: Four-channel ESD protection diode array with low capacitance and similar voltage ratings, offering a cross-manufacturer alternative.
  • SMDB03C --: Same SMDB series TVS diode array with similar 3-line protection and working voltage, widely available from Semtech as a direct functional equivalent.
