It clamps transients on a 28.2V nominal rail, with a minimum breakdown of 31.4V and a maximum clamping voltage of 45.7V at the rated Ipp. The DO-201AD axial package is through-hole, which means it survives a hot-air rework cycle without lifting a pad — the leads are robust enough to hand-solder back if a replacement is needed. ## Obsolete — sourcing through independent channels onsemi lists the 1N6283A as Obsolete. The operating temperature range is -65°C to 175°C junction, which covers military and industrial environments. The wide range does not change the obsolete status — it just means any stock you find was built to the original spec. ## Package and mounting — rework-friendly axial lead DO-201AD axial leads are through-hole — the body is 9.1 mm long typical, leads are 1.3 mm diameter. The part is, so you get loose parts, not tape-and-reel. That is fine for bench repair or low-volume production; for automated insertion you would need to confirm feeder compatibility. No power line protection — this is a unidirectional device for DC rail clamping. The single channel means one TVS per rail; if you need bidirectional, look at the 'C' suffix variants in the same series.","metaTitle":"1N6283A Zener TVS – onsemi Mosorb™ 1500W DO-201AD Obsolete","metaDescription":"1N6283A onsemi Mosorb™ Zener TVS, 1500W peak pulse, 28.2V standoff, DO-201AD axial.

We do not hold stock on the shelf. Submit an RFQ with your target quantity and we source it from our independent supply network — pricing and lead time are confirmed at quote time."},{"question":"What is the difference between 1N6283A and 1N6283?","answer":"The 'A' suffix typically indicates a tighter breakdown voltage tolerance. The 1N6283A has a minimum breakdown of 31.4V; the base 1N6283 (without 'A') has a wider tolerance. Both share the same 1500W rating and DO-201AD package."},{"question":"What package type does the 1N6283A use?","answer":"DO-201AD axial, through-hole.
