Notes:
5. Device mounted on FR-4 PCB; pad layout as shown on Diodes Inc. suggested pad layout document AP02001, which can be found on our website at
http://www.diodes.com.
6. Short duration pulse test used to minimize self-heating effect.
7. ZENER IMPEDANCE (ZZ) DERIVATION ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current applied. The
specified limits are for IZ(AC) = 0.1 IZ(DC) with the AC frequency = 60 Hz.
