Notes: 1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.

2. See http://www.diodes.com 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-Q101 qualified and are PPAP capable. Automotive, AEC-Q101 and standard products are electrically and thermally
the same, except where specified.

Electrostatic Discharge - Machine Model ESD MM ≥ 400 V C

Notes: 6. For a device surface mounted on 25mm X 25mm FR4 PCB with high coverage of single sided 1 oz copper, in still air conditions; device measured when

operating in steady state condition.

7. Same as note (6), except the device is mounted on 50mm X 50mm single sided 2oz weight copper.

8. Thermal resistance from junction to solder-point (at the end of the collector lead).

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