Mechanical Data
Case: SOT-23 Plastic Package Weight: Approx. 0.008g Packaging Codes/Options: E8/10K per 13" reel (8mm tape), 30K box E9/3K per 7" reel (8mm tape), 30K box
* Silicon Planar Power Zener Diodes * The Zener voltages are graded according to the international E 24 standard. Standard Zener voltage tolerance is 5%. Replace "C" with "B" for 2% tolerance. Other voltage tolerances and other Zener voltages are available upon request. * These diodes are also available in other case styles and other configurations including: the SOD-123 case with type designation BZT52 series, the dual zener diode common anode configuration in the SOT-23 case with type designation AZ23 series and the dual zener diode common cathode configuration in the SOT-23 case with type designation DZ23 series.
