Description
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 0.35 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 2.8 W dissipation power rating, making it capable of handling more than 140 W Continuous Wave (CW) and 500 W peak (1 μs pulse, 1 percent duty cycle) in a shunt-connected transmit/receive (T/R) switch.

FEATUREs
• Low-thermal resistance: 22 °C/W
• Suitable for 140 W Continuous Wave T/R switches
• Low capacitance: 0.3 pF
• Low distortion performance
• QFN (3-pin, 2 x 2 mm) package (MSL1, 260 °C per
   JEDEC J-STD-020)

APPLICATIONs
• Low loss, high power switches
• Low distortion attenuators
