Notes:
1. Above graph is accurate for NON REPETITIVE applications operating in an ambient
temperature of 70°C or less. For temperatures above 70°C, the graph power must be derated
further linearly down to zero at 125°C.
2. For appl icable surge power in continuous-surge applications pl ease see SURGE POWER
