Notes:  

5. For a device mounted with the collector lead on minimum recommended pad layout 1oz copper that is on a single-sided 1.6mm FR-4 PCB; device is  

measured under still air conditions whilst operating in a steady-state.  

6. Refer to JEDEC specification JESD22-A114 and JESD22-A115.  

7. Short duration pulse test used to minimize self-heating effect.
