PS2915-1 is an optically coupled isolator containing GaAs light emitting diodes and an NPN silicon phototransistor in one package for high density mounting applications. An ultra small flat-lead package has been provided which realizes a reduction in mounting area of about 30% compared with the PS28xx series.
The PS2915-1 is an optically coupled isolator that combines a GaAs LED and an NPN phototransistor in an ultra‑small flat‑lead 4‑pin package, suited for high‑density mounting. It is intended for applications such as DC/DC converters and modem/PC cards.
The sheet lists mechanical dimensions, electrical characteristics, safety approvals (UL, BSI, DIN EN60747‑5‑2), and ordering options, along with recommended mounting pad dimensions and handling precautions for the GaAs material.
