Its minimum breakdown voltage is 7.79V, and it clamps at 12.1V at the peak pulse current of 124A under the 10/1000µs waveform. The 1500W peak pulse power rating makes it suitable for general-purpose surge protection in surface-mount designs using the DO-214AB (SMC) package. ## Sourcing reality: obsolete status This part is marked Obsolete by onsemi. For existing BOMs, we can source remaining inventory from our supply network — submit an RFQ with your target quantity and date code requirements. ## Key ratings for your BOM decision The reverse standoff voltage is 7.02V, meaning this diode will not conduct appreciably below that rail voltage. The breakdown window starts at 7.79V min, so a 5V rail is too low — the TVS would never trigger. It is unidirectional only; for bidirectional protection you need a different part number. Operating temperature spans -65°C to 150°C junction, covering industrial and some automotive underhood environments. The DO-214AB package is hand-solderable with care — the large tab helps heat sinking.","metaTitle":"1.5SMC8.2AT3G onsemi TVS Diode – 7.79V Breakdown, 1500W","metaDescription":"onsemi 1.5SMC8.2AT3G Zener TVS, 7.79V min breakdown, 12.1V clamp, 1500W peak pulse.
