DATA SHEET AF002C1-39, AF002C1-39LF, AF002C4-39, AF002C4-39LF: GaAs IC Control FET Series 300 kHz–2.5 GHz Pin Out Features ● Drain (D) Source (S) ● 2 1 Low-cost SOT-23 package Series or shunt configuration ● Low DC current drain ● Ideal switch building blocks ● Pin diode replacements ● High-power antenna switches ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 250 °C per JEDEC J-STD-020 3 Gate (G) Description This group of GaAs control FETs can be used in both series and shunt configurations. They incorporate on-chip circuitry that eliminates the need for extra bias components and minimizes power drain to typically 25 µW. These features make the devices ideal replacements for PIN diodes, where low DC drain is critical. Isolation performance degrades at higher frequencies due to package parasitics. They can be tuned out in narrow band applications as shown in the circuit examples on the following pages. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.
