Description
The SMP1307 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 175
m I region of these PIN
diodes makes them very attractive for use in very low
distortion PI and TEE attenuators commonly used in TV
distribution applications. The 1.5
S typical carrier
lifetime of these diodes results in resistance of 100
maximum at 1 mA and 10
maximum at 10 mA. Available
in a selection of plastic packages, as a single diode in the
small footprint SOD-323, and in a variety of configurations
in the SOT-23. Also available in a SOT-5 (SMP1307-027)
package as a four diode array designed for insertion in the
commonly used 4 diode PI attenuator circuit.
