DATA SHEET SMP1304 Series: Low-Distortion Attenuator Plastic Packaged PIN Diodes Applications * TV distribution * Attenuator circuits Features * Low-distortion design * Frequency range from 5 MHz to >2 GHz * Designed for base station applications * Configured for PI and TEE attenuators * Packages rated MSL1 @ 260 C per JEDEC J-STD-020 Description The SMP1304 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes is designed for attenuator applications from 5 MHz to beyond 2 GHz. The thick 100 m I region of these PIN diodes makes them very attractive for use in low-distortion PI and TEE attenuators commonly found in TV distribution applications. The 1 s typical carrier lifetime of these diodes results in a resistance of 20 maximum at 1 mA and 7 maximum at 10 mA. The SMP1304 series is available in a selection of plastic packages: as a single diode in small footprint SOD-323 and SC-79 packages, and in a variety of configurations in an SOT-23 package, including the low inductance (0.4 nH) SMP1304-007. The SMP1304-019, a three-diode junction designed for insertion in PI attenuators, is available in an SOT-143 package. The SMP1304-027 is available in an SOT-5 package as a four-diode array designed for insertion in commonly used four-diode PI attenuator circuits. Table 1 describes the various packages and marking of the SMP1304 series.

SMP1304-007 The inductance of the SMP1304-007 is effectively reduced to 0.4 nH compared to the 1.5 nH of the standard configuration. The lower inductance is particularly beneficial when the diodes are used as shunt-connected switches at frequencies >500 MHz where inductance is the primary limitation on maximum switch isolation. To achieve the effective 0.4 nH, the SMP1304-007 must be inserted in the microstrip circuit board with a gap in the trace as shown in Figure 1. Because of the polarity of the diode junction, the low inductance can only be achieved with the cathode connected to ground. insertion in PI attenuator circuits in common use from 10 MHz to >1 GHz. The SMP1304-019 PIN diode junction was designed for low capacitance, a wide resistance dynamic range, and low distortion performance. Electrical and Mechanical Specifications The absolute maximum ratings of the SMP1304 series are provided in Table 2. Electrical specifications are provided in Table 3. Resistance versus temperature measurements are provided in Table 4. Typical performance characteristics of the SMP1304 series are illustrated in Figures 3 to 6. Package dimensions are shown in Figures 7 to 15 (odd numbers), and tape and reel dimensions are provided in Figures 8 to 16 (even numbers). Package and Handling Information Figure 1. SOT-23 Package Trace Gap Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SMP1304 series is rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. It can be used for lead or lead-free soldering.

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. The SMP1304 series PIN diodes are Class 1C ESD devices. Table 3.
