SMP1322 Series
Low Resistance, Plastic Packaged PIN Diodes

The SMP1322 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 ultra-low resistance of these diodes (1.5 Ω maximum at 1 mA and 0.5 Ω typical at 10 mA) makes the SMP1322 series particularly suited to low-loss PIN diode switches in battery operated circuits.

The SMP1322 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 miniature SOD-323, the ultra-low inductance SOT-143 (0.2 nH), and a miniature SOD-882.

The SMP1322-016 consists of two diodes in an SOT-143 package configured to enable insertion in a quarter-wave transmit/receive (T/R) switch with no crossover connections.

Features

  • Resistance: 0.8 Ω typical @ 1 mA
  • Packages rated MSL1, 260 °C per JEDEC J-STD-020)
