Product details

What this Zener TVS does on the board

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.

onsemi lists the 1N6283A as Obsolete. 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. The single channel means one TVS per rail; if you need bidirectional, look at the 'C' suffix variants in the same series.

Frequently asked questions

How can I order the 1N6283A or check stock?

The 1N6283A is obsolete per onsemi. 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.

What is the difference between 1N6283A and 1N6283?

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.

What package type does the 1N6283A use?

DO-201AD axial, through-hole. The supplier device package is also listed as Axial. It is a two-lead package with a 0.375-inch body length typical.
