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
µm
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
µS
typical carrier
lifetime of these diodes results in resistance of 100
Ω
maximum at 1 mA and 10
Ω
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.
