The SMP1304-085LF is a surface mountable, low capacitance silicon PIN diode designed as a shunt connected PIN diode for high power, high volume switch and attenuator applications from 10 MHz to beyond 6 GHz.

Maximum resistance at 100 mA is 2 Ω and maximum capacitance at 30 V is 0.3 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 100 μm I-region width, makes the diode useful in large signal switches and attenuator applications.

The device has a 3 W dissipation power rating, making it capable of handling more than 100 W Continuous Wave (CW) and 500 W peak (1 μs pulse, 1 percent duty cycle) in a shunt-connected transmit/receive (T/R) switch.

The general market diode is ideal for the infrastructure and land mobile radio markets.
