PNP/PNP matched double transistors

PNP/PNP matched double transistors in small Surface-Mounted Device (SMD) plastic packages. The transistors are fully isolated internally.

Features and benefits

  • Current gain matching
  • Base-emitter voltage matching
  • Drop-in replacement for standard double transistors
  • AEC-Q101 qualified


  • Current mirror
  • Differential amplifier
