CNY21Exi Datasheet
TELEFUNKEN Semiconductors
Optocoupler with Phototransistor Output
Description
The CNY21Exi consists of a phototransistor optically coupled to a gallium arsenide infrared emitting diode in a 4 lead plastic dual inline packages. The single components are mounted on one leadframe in opposite position, providing a fixed distance between input and output for highest safety requirements of > 3 mm.
CNY21Exi
95 10533
Applications
Used for circuits with intrinsic safety Ex-i (G5).
PTB-approval-file number Ex-90.C.2106 U confirms, that this coupler can be used for intrinsic circuits up to a line voltage in series ≤ 375 V.
Features
D UL-recognized-file No: E 76414
D DC isolation test voltage: 10 kV
D Creeping current resistance of isolation material according to VDE 0303/DIN 53480: KB ≥ 150/KC ≥ 175
D Isolation material according to UL 94 -flammability class
D Test class 25/100/21 DIN 40045 D Very low coupling capacity, typical 0.3 pF
therefore high noise voltage resistant D Current Transfer.
