Notes:
1. RoHS revision 13.2.2003. Glass and high temperature solder exemptions applied, see EU Directive Annex Notes 5 and 7.
2. Thermal resistance from junction to lead vertical PC board mounting, 9.5mm lead length.
3. Device mounted to heat sink with 1/8" lead length.
4. Pulse width ≤ μs - Duty Cycle ≤ 2%.
5. Short duration pulse test used to minimize self-heating effect.
