Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html 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. Automotive products are AEC-Q10x qualified and are PPAP capable. Automotive, AEC-Q10x and standard products are electrically and thermally the
same, except where specified. For more information, please refer to http://www.diodes.com/quality/product_compliance_definitions/.

Notes: 6. For a device mounted with the exposed collector pad on 15mm x 15mm 1oz copper that is on a single-sided 1.6mm FR4 PCB; device is measured
under still air conditions whilst operating in a steady-state.

7. Same as note (5), except the device is mounted on 25mm x 25mm 1oz copper.

8. Same as note (5), except the device is mounted on 50mm x 50mm 1oz copper.

9. Thermal resistance from junction to solder-point (on the exposed collector pad).

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