SMP1325-087LF

Surface Mount PIN Diode

The SMP1325-087LF is a surface mountable PIN diode suitable for use in an RF switch or attenuator circuit.

Maximum resistance at 100 mA is 0.55 Ω and maximum capacitance at 20 V is 0.6 pF. The combination of low capacitance, low parasitic inductance, low thermal resistance, and nominal 100 μm I-region width, makes the SMP1325-087LF useful in large signal switches and attenuator applications.

The device has a 2 W dissipation power rating, which makes it capable of handling up to 50 W Continuous Wave (CW) and 500 W peak (1 μs pulse, 1 percent duty cycle) in a shunt-connected transmit/receive (T/R) switch.

Design information for high power switches may be found in the Skyworks Application Note, Design With PIN Diodes (document number 200312).
