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 websit5. 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 at7. Measured across either pin 1 and pin 3 or pin 2 and pin 3.
