IS725SM

Transistor, Photovoltaic Output Optoisolators Overview

The IS725SM is a high-voltage Darlington output optically coupled isolator manufactured by Isocom Components. It integrates an infrared LED with a high-voltage NPN silicon photo-Darlington transistor featuring an integral base-emitter resistor to optimize switching speed and elevated temperature performance. The device provides high isolation voltage of 5.3kVRMS and 7.5kVPK, ensuring robust signal transmission between systems with different potentials. Key electrical parameters include a minimum current transfer ratio of 1000%, a minimum collector-emitter breakdown voltage (BVCEO) of 300V, and a maximum collector dark current of 1μA at 200V VCE. The input forward current is specified at 1mA. This component is housed in a surface-mount package variant of the standard 6-pin dual in-line plastic configuration.
