PZ1418B30U - NPN microwave power transistors

General Description

NPN silicon planar epitaxial microwave power transistor in a SOT443A metal ceramic flange package with the base connected to the flange.

Fig.1 Simplified outline and symbol.

Key Features

  • Interdigitated structure provides high emitter efficiency.
  • Diffused emitter ballasting resistors providing excellent current sharing and withstanding a high VSWR.
  • Gold metallization realizes very stable characteristics and excellent lifetime.
  • Multicell geometry gives good balance of dissipated power and low thermal resistance.
  • Internal input and output prematching ensures good stability and easy broadband use.
