HJ814

HJ814 is a fully sealed, single-channel optocoupler. It consists of a GaAsP light-emitting diode and an optically coupled NPN phototransistor, featuring input compatibility with TTL circuits, an output transistor with a breakdown voltage exceeding 35 V, an input–output insulation resistance greater than 10 Ω, an isolation voltage of ≥1000 V, and a relatively high current transfer ratio. The device is housed in a dual‑in-line ceramic package and operates over a temperature range of −55 to +125 °C.
