SMP1304-087LF

Surface Mount PIN Diode

Please note: SMP1304-087LF is being discontinued and is not recommended for new designs. The suggested replacement is SMP1304-079LF



The SMP1304-087LF is a surface mountable PIN diode suitable for use in an RF switch or attenuator circuit.

Maximum resistance at 100 mA is 2.0 Ω and maximum capacitance at 30 V is 0.3 pF. The combination of low capacitance, low parasitic inductance, low thermal resistance, and nominal 100 μm I-region width, makes the SMP1304-087LF useful in large signal switches and attenuator applications.

The device has a 3 W dissipation power rating, which makes it capable of handling up to 125 W @ 25 °C Continuous Wave (CW) in a series-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).
