The data sheet introduces the features of Agilent HSMP-381x, 481x Surface Mount RF PIN Low Distortion Attenuator Diodes, including packages, maximum working frequency, maximum working current, maximum reverse voltage, etc.
The HSMP‑381x and HSMP‑481x series are surface‑mount RF PIN diodes designed for low‑distortion attenuation at microwave frequencies. They are offered in single‑ and dual‑cathode versions and are available in SOT‑23 and SOT‑323 (SC‑70) packages with bulk, tape, or reel options.
Key electrical parameters include a forward current rating of 1 A (1 µs pulse), a junction temperature limit of 150 °C, and storage temperature range from –65 °C to 150 °C. The devices feature ultra‑low parasitic inductance and capacitance (typical 0.08 pF) and are qualified for a maximum soldering temperature of 260 °C for 5 seconds. Recommended PCB footprints and assembly profiles are provided to ensure reliable surface‑mount assembly.
