Product details

1500W peak pulse – the surge rating that defines the protection window

Breakdown voltage starts at 37.1V minimum, clamping at 53.9V maximum at the peak pulse current, with a 33.3V reverse standoff. The standoff voltage is the DC rail the part sits across without conducting; the clamp voltage is where the TVS forces the surge current to ground. The gap between them — roughly 20V — is the protection window the load must survive.

onsemi lists the 1N6285ARL4 as Obsolete. The package is axial, through-hole, supplied on Tape & Reel. That package is common across the 1N6285 family, so a same-package sibling (e.g. 1N6285A) is a drop-in candidate if the electrical ratings match the application.

Through-hole axial mounting simplifies hand-rework and retrofit but occupies more board area than a surface-mount equivalent.

Frequently asked questions

How can I order 1N6285ARL4 or check stock?

The 1N6285ARL4 is obsolete and not available through franchised distribution. We can source it through our independent supply network — submit an RFQ with your target quantity and we will confirm availability and current pricing at quote time. No stock-holding claim is made here.

Is 1N6285ARL4 compatible with 1N6285A?

The base product number is 1N6285, and the suffix 'ARL4' indicates a specific packaging option (Tape & Reel). The 1N6285A variant shares the same DO-201AD package and electrical ratings (37.1V breakdown min, 53.9V clamping max, 33.3V standoff) — it is a drop-in replacement if the reel packaging is not required. Confirm the exact voltage ratings match your application.

What is the peak pulse power of 1N6285ARL4?

This is the maximum surge energy the device can absorb in a single event.
