HSMP-382x, 482x Surface Mount RF PIN Switch and Limiter Diodes Data Sheet
The HSMP‑382x and HSMP‑482x series are surface‑mount RF PIN switch and limiter diodes optimized for ultra‑low resistance, low distortion attenuation, and power‑limiting applications up to 1.5 GHz. They are offered in single and dual‑anode versions, in SOT‑23 and SOT‑323 packages, with lead‑free and RoHS‑compliant options.
The handbook contains absolute maximum ratings, electrical specifications, typical performance parameters, recommended PCB footprints, SMT assembly profiles, package dimensions, ordering information, and tape‑and‑reel handling details. It also includes application schematics for SPDT and SPST switches, biasing arrangements, and microstrip integration techniques.
| Forward Current (1 µs Pulse) | 1 A |
|---|---|
| Peak Inverse Voltage | 50 V |
| Junction Temperature | 150 °C |
| Storage Temperature | -65 °C to 150 °C |
| Package Inductance | 2 nH |
| Maximum Reflow Peak Temperature | 260 °C |
The maximum forward current is 1 A for a 1 µs pulse.
The peak reflow temperature should not exceed 260 °C, with a typical profile staying within that limit.
They are available in bulk (100 pcs per bag) or tape‑and‑reel formats such as TR1G (3000 devices per 7‑inch reel) and TR2G (10 000 devices per 13‑inch reel).
