Phototransistor optocoupler Broadcom 4N25-000E offering signal transmission and wide lead spacing options
Product Overview
The 4N25 is a general-purpose optocoupler designed for reliable signal transmission between circuits of different potentials and impedances. It integrates a light-emitting diode optically coupled to a phototransistor, housed in a 6-pin DIP package. This optocoupler offers a fast response time of typically 3 s and a minimum Current Transfer Ratio (CTR) of 20% at an input current of 10 mA. Its robust input-output isolation voltage of 2500 Vrms makes it suitable for various applications including I/O interfaces for computers, system appliances, and measuring instruments. Available options include wide-lead spacing and surface-mount configurations.
