SMP1304-011

The SMP1304 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes are designed for use in attenuator applications from 5 MHz to beyond 2 GHz. The thick 100 µm I region of these PIN diodes makes SMP1304 series  very attractive for use in low distortion PI and TEE attenuators commonly used in TV distribution applications. The 1 µS typical carrier lifetime of these diodes results in resistance of 20 Ω maximum at 1 mA and 7 Ω maximum at 10 mA. Available in a selection of plastic packages: as a single diode in the small footprint SOD-323 package and in a variety of configurations in the SOT-23 package, including a low inductance (0.4 nH) SMP1304-007 package. Also available in the SOT-143 package are three diode junctions designed for insertion in TEE attenuators (SMP1304-018) and PI attenuators (SMP1304-019). Also available in a SOT-5 (SMP1304-027) package as a four diode array designed for insertion in the commonly used 4 diode PI attenuator circuit.
