SMP1304-027LF

The SMP1304-027LF is a surface-mount PIN diode array from Skyworks Solutions, part of the SMP1304 series optimized for low-distortion attenuator circuits. It is configured as a 2-pair common anode and common cathode array, suitable for PI and TEE attenuator topologies. Electrical specifications include a maximum reverse voltage of 200V, typical capacitance of 0.3 pF at 30V and 1 MHz, and maximum series resistance of 2 Ω at 100 mA and 100 MHz. The device is rated for maximum power dissipation of 250 mW and operates over a temperature range of -65°C to 150°C.

Designed for RF applications from 5 MHz to beyond 2 GHz, the SMP1304-027LF features a thick 100 μm I region that provides low distortion performance. The 1 μs typical carrier lifetime results in a resistance of 20 Ω maximum at 1 mA and 7 Ω maximum at 10 mA, ensuring consistent attenuation. The component is housed in a compact SOT-5 package, which is rated MSL1 at 260°C per JEDEC J-STD-020.

The part is lead-free and RoHS3 compliant, as indicated by the 'LF' suffix in the part number. The SMP1304-027LF is commonly used in TV distribution systems, base station equipment, and other RF attenuator applications requiring low distortion and wide bandwidth.
