DATA SHEET SMP1345-087LF: Surface Mount PIN Diode Applications • Switches • Attenuators Features • Low-series resistance: 2 Ω maximum @ 10 mA • Low total capacitance: 0.2 pF maximum @ 5 V • QFN (2 x 2 mm) package (MSL1, 260 °C per JEDEC J-STD-020) Description The SMP1345-087LF is a surface mountable PIN diode suitable for use in an RF switch or attenuator circuit. Maximum resistance at 10 mA is 2 Ω and maximum capacitance at 5 V is 0.2 pF. The combination of low capacitance, low parasitic inductance, and nominal 10 μm I-region width, makes the SMP1345-087LF useful in large signal switches and attenuator applications. The device has a 0.5 W dissipation power rating, which makes it capable of handling up to 40 W Continuous Wave (CW) and 440 W peak (1 μs pulse, 1% duty cycle) 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).

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.
