Note: 

1. Halogen free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. 

2. The value of RθJA is measured with the device mounted on 1in[2] FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. 

3. Repetitive rating; pulse width limited by max. junction temperature. 

4. PD is based on max. junction temperature, using junction-ambient thermal resistance.
