Notes: 6. Device mounted on 1.5" × 1.5", FR-4 PCB; 2 oz. Cu with 1" × 1" pa d layout.
7. Theoretical RθJS calculated from the top center of the die straight down to the PCB/cathode tab solder junction.
8. Short duration pulse test used to minimize self-heating effe ct.
9. The Zener impedance (Zzt) is measured by superimposing a minute alternating current on the regulated current (Izt).
