DATA SHEET SMP1304-085LF: Surface Mount PIN Diode for High Power Switch Applications Applications Low loss, high power switches Low distortion attenuators Features Low-thermal resistance: 35 °C/W Suitable for 100 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) Figure 1. SMP1304-085LF Block Diagram Description 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 SMP1304-085LF useful in large signal switches and attenuator applications. The device has a 2.5 W dissipation power rating, maki...
