Notes:
1. V_R = 0V, f = 1MHz.
2. Clamping voltage value is based on an 8x20 μs peak pulse current (I_pp) waveform.
3. No purposefully added lead.
4. Diodes Inc.’s “Green” policy can be found on our website at http://www.diodes.com/products/lead_free/index.php.
5. Short duration pulse test used to minimize self-heating effect.
6. Device mounted on FR-4 PC board with suggested pad layout, which can be found on our website at http://www.diodes.com/datasheets/ap02001.pdf.
7. Measured across either pin 1 and pin 3 or pin 2 and pin 3.
