1. EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. All applicable RoHS exemptions 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. LT4ME5.0 thru LT4ME24 devices that comply IEC 61000-4-2 levels.
5. Non-repetitive current pulse, per fig. 3 and derated above TA= 25℃ per fig.1.
6. Only for unidirectional units.
7. VF max=3V at IF=16 A 300us square wave pulse.
