1. Insulation characteristics are guaranteed only within the safety maximum ratings, which must be ensured by protective circuits within the
application.
2. Safety-limiting parameters are dependent on case temperature. The Input Current, IS,INPUT, derates linearly above 25°C free-air case temperature
at a rate of 1.2 mA/°C and 1.53 mA/°C for HCPL-0370 and HCPL-3700/3760 respectively; the Output Power, PS,OUTPUT, derates linearly above 25°C
free-air case temperature at a rate of 4.8 mW/°C and 4 mW/°C for HCPL-0370 and HCPL-3700/3760 respectively.
