SMP1325-085LF Block Diagram Low capacitance: 0.56 pF typical 20 V Low distortion performance Description QFN (3-pin, 2 x 2 mm) package (MSL1, 260 C per JEDEC J-STD-020) The SMP1325-085LF 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. TM Maximum resistance at 100 mA is 0.5 and maximum Skyworks Green products are compliant with capacitance at 20 V is 0.65 pF. The combination of low junction all applicable legislation and are halogen-free. capacitance, low parasitic inductance, low thermal resistance, For additional information, refer to Skyworks TM and nominal 100 m I-region width, makes the SMP1325-085LF Denition of Green , document number useful in large signal switches and attenuator applications. SQ040074. The device has a 4.5 W dissipation power rating, making it capable of handling more than 100 W continuous wave (CW) and 1000 W peak (1 s pulse, 1 percent duty cycle, TC = 85 C) in a shunt-connected transmit/receive (T/R) switch. Design information for high-power switches can be found in the Skyworks Application Note, Design With PIN Diodes (document number 200312). A block diagram of the SMP1325-085LF is shown in Figure 1.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
