This document describes the features of the K817P/ K827PH/ K847PH optocouplers, including endstackable design, DC isolation test voltage, low coupling capacitance, current transfer ratio selection, low temperature coefficient, wide ambient temperature range, etc.
The Vishay K817P, K827PH and K847PH series are optocouplers with a phototransistor output, available in single, dual and quad channel packages. They feature end‑stackable 2.54 mm spacing, low coupling capacitance (≈0.3 pF), and a wide CTR range (50‑600 %).
The document provides absolute maximum ratings, electrical and switching characteristics, package dimensions, and compliance information such as RoHS and ozone‑depleting‑substance policies.
