The SMP1302-085LF 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 1.5 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 50 μm I-region width, makes the SMP1302-085LF
useful in large signal switches and attenuator applications.
The device has a 3 W dissipation power rating, making it capable
of handling more than 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.
