Notes:
5. Standard test condition is IEC61000-4-2 level 4 test circuit with each (AOUT/BOUT) pin subjected to ±12kV contact discharge for 1000 pulses.
Discharges are timed at 1 second intervals and all 1000 strikes are completed in one continuous test run.
6. Device mounted on FR-4 PCB pad layout (2oz copper) as shown on Diodes, Inc. suggested pad layout, which can be found on our website at
http://www.diodes.com/package-outlines.html.
7. Short duration pulse test used to minimize self-heating effect.
8. Clamping voltage value is based on an 8x20µs peak pulse current (Ipp) waveform.
9. Capacitance measured from VOUT to VN with VIN floating.
