SMP1331-087LF Block Diagram Description The SMP1331-087LF is a surface mountable, low-capacitance silicon PIN diode designed as a series connected PIN diode for high-power, high-volume switch and attenuator applications from 10 MHz to beyond 6 GHz. Typical resistance at 100 mA is 0.50 Ω and maximum capacitance at 30 V is 0.35 pF. The combination of low capacitance, low parasitic inductance, and nominal 30 μm I-region width, makes the SMP1331-087LF useful in large signal switches and attenuator applications. The device has a 0.75 W dissipation power rating, which makes it capable of handling up to 45 W @ 85 °C Continuous Wave (CW) in a series-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 SMP1331-087LF 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.
