SMP1321 Series
Low Capacitance, Plastic Packaged PIN Diodes

The SMP1321 series of plastic packaged, surface mountable PIN diodes is designed for use in high volume switch applications from 10 MHz to more than 10 GHz. The low capacitance of these diodes (0.25 pF), combined with a low resistance (2.0 Ω maximum at 10 mA), makes the SMP1321 series particularly suited to high isolation, series-connected PIN diode switches in battery operated circuits.

The SMP1321 series is available in a selection of plastic packages and a variety of configurations that include an SC-70, a small footprint SC-79, a low inductance SOT-23, and a miniature SOD-882.

Features

  • Capacitance: 0.18 pF typical @ 30 V
  • Series resistance: 1.05 Ω typical @ 10 mA
  • Packages rated MSL1, 260 °C per JEDEC J-STD-020
