ACPL-827 is a DC input two-channel fully spaced phototransistor optical coupler consisting of two light-emitting diodes optically coupled to two independent transistors. It is encapsulated in an 8-pin DIP package. Similarly, ACPL-847 is a DC input four-channel full-pitch phototransistor optical coupler containing four light-emitting diodes optically coupled to four independent transistors.
ACPL-827 and ACPL-847 Pin arrangement
It comes in a 16-pin DIP package. Both couplers have wide lead spacing options and lead bending SMD options, and the input-output isolation voltage is 5000 Vrms. At an input current of 5 mA, tr is usually 4 μs and CTR is 50%.
Solder return temperature profile
（1）One-time welding reflow welding is recommended under the conditions of temperature and time profile as shown in the following figure.
（2）When other welding methods such as infrared lamps are used, the temperature in the equipment mold may partially rise.
