Application Scenarios & Design Considerations

Unidirectional TVS Array for Protection of Four Lines

Alternative Part Number

  • SRV05-4 --: Same manufacturer's TVS diode array family with similar multi-line ESD protection characteristics, often used as a drop-in for SMDA15 in data-line protection.
  • SP0504BAHT --: Four-channel TVS diode array offering comparable clamping voltage and ESD protection, suitable replacement for SMDA15 in interface protection.
  • USBLC6-4SC6 --: Quad-line ESD protection array with similar working voltage and low capacitance, a common cross-reference for SMDA15 in USB and data-line applications.
  • SDA15 --: Similar 15V TVS diode array in a comparable package with equivalent clamping performance, widely available and pin-compatible for most SMDA15 applications.
  • PESD15VS2UT --: 15V ESD protection diode with low capacitance, suitable as a functional replacement for transient suppression in signal lines where SMDA15 is used.
  • CDSOT23-SM712 --: TVS diode array in SOT-23 package offering comparable 15V-class transient protection, usable as an alternative with layout verification.
