Note 1. These ratings are limiting values above which the serviceability of this device may be impaired.
Note 2. This rating refers to a high current point where collector to emitter voltage is lowest.
Note 3. These ratings are steady state limits.
Note 4. These ratings give a maximum junction temperature of +200
°
C and junction to case thermal
resistance of +25
°
C/W (derating factor of 40mW/
