描述 Description

The SMP1331-087LF is a surface mountable, low-capacitancesilicon PIN diode designed as a series connected PIN diode forhigh-power, high-volume switch and attenuator applications from10 MHz to beyond 6 GHz.

Typical resistance at 100 mA is 0.50 Ω and maximumcapacitance at 30 V is 0.35 pF. The combination of lowcapacitance, low parasitic inductance, and nominal 30 μmI-region width, makes the SMP1331-087LF useful in large signalswitches and attenuator applications.

The device has a 0.75 W dissipation power rating, which makes itcapable of handling up to 45 W @ 85 °C Continuous Wave (CW) ina series-connected transmit/receive (T/R) switch.

Design information for high-power switches may be found in theSkyworks Application Note, Design With PIN Diodes (documentnumber 200312).
