When the voltage across it exceeds the 34.2 V minimum breakdown threshold, it conducts avalanche current and holds the clamp at 49.9 V maximum. Rated for 1500 W peak pulse power (1.5 kW) under the 10/1000 µs waveform, this part handles the kind of energy a 24 V industrial supply line or automotive load-dump event throws at it. The DO-201AD axial package means it solders into a through-hole board — the leads carry the surge current into the silicon junction, so the PCB trace width to and from the anode/cathode matters for the peak current path. onsemi lists the 1N6284A as Obsolete. No direct factory orders or lifecycle buy window remains open. We source and quote the 1N6284A to order against your BOM quantity — confirm the date code and lot traceability requirements at quote time. The operating temperature range spans -65°C to 175°C junction, which covers military and downhole environments. That wide range is typical for a through-hole TVS — the axial package and large die handle the thermal cycling without the solder-joint fatigue risk of a surface-mount part. ## Clamping voltages and the protection window The reverse standoff voltage of 30.8 V is the maximum DC or AC peak voltage the diode can sit across without conducting leakage current. The breakdown voltage range starts at 34.2 V — that is where avalanche begins. Under a surge, the clamp holds at 49.9 V maximum. Power line protection is marked as No, which means this diode is not rated for continuous AC mains overvoltage — it is a transient suppressor, not a crowbar or a varistor. Use it on DC buses, signal lines, or low-frequency AC where the surge is a one-off event.","metaTitle":"1N6284A onsemi TVS Diode – 1500 W, 30.8 V Standoff, DO-201AD","metaDescription":"onsemi 1N6284A Mosorb™ Zener TVS, 1500 W peak pulse, 30.8 V reverse standoff, unidirectional, DO-201AD axial.
