DATA SHEET SMP1331-085LF: 50 W Surface Mount Shunt Connected PIN Diode Applications Anode Anode (Pin 3) (Pin 1) Low-loss, high-power switches Low distortion attenuators Features Cathode Low-thermal resistance: 28 C/W (Pin 2, Exposed Paddle) Suitable for 50 W Continuous Wave T/R switches Figure 1. SMP1331-085LF Block Diagram Low capacitance: 0.35 pF Low distortion performance Description QFN (3-pin, 2 2 mm) package (MSL1, 260 C per JEDEC J-STD-020) The SMP1331-085LF 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 Skyworks Green products are compliant with 10 MHz to beyond 6 GHz. all applicable legislation and are halogen-free. Maximum resistance at 100 mA is 0.5 and typical capacitance For additional information, refer to Skyworks at 30 V is 0.35 pF. The combination of low junction capacitance, Denition of Green, document number low parasitic inductance, low thermal resistance, and nominal SQ04-0074. 30 m I-region width, makes the SMP1331-085LF useful in large signal switches and attenuator applications. The device has a 2.5 W dissipation power rating, making it capable of handling more than 50 W 85 C Continuous Wave (CW) in a shunt-connected transmit/receive (T/R) switch. Design information for high power switches may be found in the Skyworks Application Note, Design With PIN Diodes (document number 200312). A block diagram of the SMP1331-085LF 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.
