applied.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and
Antimony-free, "Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine
(<1500ppm total Br + Cl) and <1000ppm antimony compounds.
4. Perform static test after the temperature of oven is steady 20 minutes.
5. Measured at 1.0MHz and applied reverse voltage of 4.0V DC
6. Thermal resistance junction to case, lead and ambient in accordance with JESD-51. Unit mounted on 15mmx12mmx1.6mm AL
Pad attached on 40mmx30mmx24mm Fin heatsink.
