Product details

onsemi lists the 1N6283ARL4 as obsolete. We source it through our multi-supplier network against an RFQ.

Peak pulse power and clamping for 28 V rails

The reverse standoff voltage is 28.2V, which means it sits across a 24 V or 28 V DC rail without conducting in normal operation. Breakdown occurs at 31.4V minimum, so the device starts shunting surge current before the rail exceeds the downstream component's absolute maximum.

Single unidirectional channel in DO-201AD axial

One unidirectional channel in a through-hole axial package.

Frequently asked questions

How can I order the 1N6283ARL4 or check availability?

The 1N6283ARL4 is obsolete per onsemi. We source it through our independent distribution network against an RFQ. Submit your BOM quantity; we confirm current availability and pricing at quote time. No stock count or lead time is published here.

What is the difference between 1N6283A and 1N6283ARL4?

The 1N6283ARL4 suffix indicates Tape & Reel packaging (TR), while the base 1N6283A is typically supplied in bulk or other packaging formats. Electrical specifications — 28.2V standoff, 31.4V breakdown, 45.7V clamp, 1500W peak pulse — are identical between the two.
