HJ521 single-channel optocoupler
Release time:
2014-06-04
HJ521 is a fully sealed single-channel optocoupler circuit. It consists of a CaAsP light-emitting diode and an optically coupled NPN phototransistor, featuring compatibility with TTL circuits for input, an output transistor with a breakdown voltage greater than 35V, an insulation resistance between input and output greater than 10^10Ω, an isolation voltage of ≥1000V, and a high current transfer ratio. It uses a special dual in-line 4-pin ceramic package (with a shell length shorter than the standard package length to facilitate multi-channel optocoupler installation on printed circuit boards), and operates within a temperature range of -55~
