The BA282/BA283 are Vishay Semiconductors' silicon planar diodes that have a low differential forward resistance, low diode capacitance and a high reverse impedance. Applications include band switching in VHF tuners.
The BA282 and BA283 are silicon planar band‑switching diodes intended for VHF‑tuner applications. They feature low differential forward resistance, low capacitance and high reverse impedance, making them suitable for high‑frequency switching.
The datasheet lists key parameters such as a 35 V reverse voltage, 100 mA forward current, and junction temperature up to 150 °C. Mechanical data include a DO‑35 glass case with a maximum weight of 130 mg, and packaging options of tape‑and‑reel or Ammopack.
