Overview

The PS2861B-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon phototransistor. The package has a shield effect to cut off ambient light, and is mounted in a Shrink SOP (Small Outline Package) for high density applications. Due to the high isolation voltage between the input and output, the PS2861B-1 is suitable for interface and signal transfer circuits that require surface or high-density mounting.

  • Operating ambient temperature: 110°C
  • Isolation distance (0.4 mm MIN.)
  • High isolation voltage (BV = 3 750 Vr.m.s.)
  • Shrink SOP (Small Outline Package) type
  • High-speed switching (tr = 4μs TYP., tf == 5μs TYP.)
  • Embossed tape product: PS2861B-1-F3: 3 500 pcs/reel
  • Pb-Free product
  • Safety standards UL approved: UL1577, Single protection CSA approved: CAN/CSA-C22.2 No. 62368-1, Reinforced insulation BSI approved: BS EN 62368-1, Reinforced insulation SEMKO approved: EN 62368-1, IEC 62368-1, Reinforced insulation NEMKO approved: EN 62368-1, Reinforced insulation FIMKO approved: EN 62368-1, Reinforced insulation DEMKO approved: EN 62368-1, Reinforced insulation CQC approved: GB8898, GB4943.1, Reinforced insulation VDE approved: DIN EN 60747-5-5 (Option)
