OPI7010 [Optek]

These optically coupled isolators consist of an infrared emitting diode coupled to either a NPN silicon phototransistor (OPI7002, OPI7010) or a NPN silicon photodarlington (OPI7320RCE, OPI7340RCE). They are encased in plastic housing (black low-cost for phototransistor, high dielectric for photodarlington) with pin spacing compatible with standard dual-in-line packages. The RCE versions reverse the emitter and collector pin-out. Key features include ±6 kV DC electrical isolation, inexpensive plastic housing, and UL registration (File No. E58730).
