Application Scenarios & Design Considerations

Low Capacitance Plastic Packaged PIN Diodes

Alternative Part Number

  • BAR64-02V --: PIN diode in a similar small SMD package with comparable switching and low-capacitance characteristics, suitable as a functional replacement in RF switching and attenuator circuits.
  • HSMP-3810 --: PIN diode from a well-known RF diode family offering similar low insertion loss and low capacitance, commonly used as a cross-reference for Skyworks SMP1321 series parts.
  • MA4P1250-1072 --: PIN diode with comparable RF performance and power handling, usable as an alternative when the SMP1321-011 is unavailable, though package and exact parasitics should be verified.
