Application Note Remote ON/OFF Control Derating The CHB100/150 Series allows the user to switch the module on and off electronically with remote on/off feature. The CHB100/150 Series are available with "positive logic" or "negative logic" (option). The operating case temperature range of the CHB100/150 series is -40˚C to +100˚C. When operating the CHB100/150 series, proper derating or cooling is needed . Logic Table Following is the derating curve of CHB100/150 without heat sink.
