• The Zener voltages are graded according to the
international E24 standard. Standard Zener
voltage tolerance is ± 5 %, indicated by the “C”
in the ordering code. Replace “C” with “B” for
± 2 % tolerance.
• AEC-Q101 qualified
• ESD capability acc. to AEC-Q101:
human body model: > 8 kV,
machine model: > 800 V
• Base P/N-E3 - RoHS-compliant, commercial grade
• Base P/N-HE3 - RoHS-compliant, AEC-Q101 qualified
• Material categorization: For definitions of compliance
