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.
