Overview

The PS9905 is optically coupled isolator containing an AlGaAs LED on the input side and a photo diode, a signal processing circuit and a power output transistor on the output side on one chip.

  • Long creepage distance (15 mm MIN.)
  • Large peak output current (2.5 A MAX., 2.0 A MIN.)
  • High speed switching (tPLH, tPHL = 0.15 μs MAX.)
  • UVLO (Under Voltage Lock Out) protection with hysteresis
  • High common mode transient immunity (CMH, CML = ±25 kV/μs MIN.)
  • 8-pin LSDIP (Long Creepage SDIP) type
  • Embossed tape product: PS9905-F3: 1000 pcs/reel
  • Pb-Free Product
  • Safety standards
