K814P

The Vishay K814P is an optocoupler designed with a phototransistor output, optically coupled to gallium arsenide infrared emitting diodes. It supports both AC and DC input signals and offers a high isolation test voltage of 5000 VRMS. This component is suitable for applications requiring reliable signal isolation.

The K814P features a current transfer ratio (CTR) ranging from a minimum of 20% at 5mA to a typical maximum of 300% at 5mA. Its output transistor has a collector-emitter voltage of up to 70V and can handle a continuous collector current of 60mA. The device exhibits fast switching characteristics with typical turn-on times of 6µs and turn-off times of 5µs, and rise times of 3µs.

This optocoupler operates within a wide ambient temperature range of -40°C to 100°C. It is packaged in a standard 4-DIP (Dual In-line Package) with a 7.62mm pitch, designed for through-hole mounting. The K814P is agency certified by UL, cUL, and CQC, indicating compliance with relevant safety standards.

Applications for the K814P include feature phones, answering machines, PBX systems, and fax machines, where robust isolation is critical. Its construction provides a fixed distance between input and output for enhanced safety requirements.
