CNY21N Datasheet Optocoupler

Manufacturer: TEMIC Semiconductors (now Microchip)

Overview: Optocoupler with Phototransistor Output.

General Description

The CNY21N consists of a phototransistor optically coupled to a gallium arsenide infrared emitting diode in a 4-lead plastic dual inline package.

The single ponents are mounted on one leadframe in the opposite position, providing a fixed distance between input and output for highest safety requirements of > 3 mm.

Application Circuits for safe protective separation against electrical shock according to safety class II (reinforced isolation): D For application class I - IV at mains voltage ≤ 300 V D For application class I - IV at mains voltage ≤ 600 V D For application class I - III at mains voltage ≤ 1000 V according, to VDE 0884, table 2, suitable for: Switch-mode power supplies, puter peripheral interface, microprocessor system interface, line receiver.

Key Features

  • According to VDE 0884 D Rated impulse voltage (transient overvoltage) VIOTM = 8 kV peak D Isolation test voltage (partial discharge test voltage) Vpd = 2.8 kV peak D Rated isolation voltage (RMS includes DC) VIOWM = 1000 VRMS (1450 V peak) D Rated recurring peak voltage (repetitive) VIORM = 1000 VRMS D Creeping current resistance according to VDE 0303/IEC 112 Comparative Tracking Index: CTI = 275 D Thickness through insulation > 3 mm D Isolation materials according to UL 94 D Pollution degree.
