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
specified limits are for I
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
Z(AC)
= 0.1 I
with the AC frequency = 60 Hz.
