Product details

Transient suppressor for 12 V rails — 1500 W peak pulse

The 1N6275ARL4 is a 1500 W peak pulse power Zener TVS diode from the onsemi Mosorb™ series, designed to clamp transients on a 12.8 V nominal rail (reverse standoff) with a breakdown voltage minimum of 14.3 V and a maximum clamping voltage of 21.2 V at the peak pulse current.

Obsolete — plan a replacement now

onsemi lists the 1N6275ARL4 as Obsolete. No official successor is cited.

Through-hole axial — DO-201AD footprint

The DO-201AD axial package with through-hole mounting suits point-of-use transient clamping on a PCB or terminal strip. The -65°C to 175°C junction temperature range covers military and industrial environments.

Frequently asked questions

How can I order 1N6275ARL4 or check stock?

onsemi lists this part as Obsolete, so new factory orders are not available. We source from our multi-supplier network — submit an RFQ with your target quantity and we will confirm availability and current pricing from distributor inventory or the spot market. The RL4 suffix indicates Tape & Reel packaging; if you need bulk tubes or cut tape, note that on the RFQ.

What is the difference between 1N6275A and 1N6275ARL4?

The base product number is 1N6275. The 'A' suffix typically denotes a tighter tolerance or a specific breakdown voltage bin. The 'RL4' suffix indicates Tape & Reel packaging. The die and electrical ratings (1500 W peak pulse, 12.8 V standoff, 21.2 V clamping) are identical between the two suffixes — the difference is only the packaging format.

What is the closest pin-compatible alternative to 1N6275ARL4?

Within the same onsemi Mosorb™ family, the 1N6275A (same base product number, bulk packaging) is electrically identical. For a second-source alternative, look for a Zener TVS in DO-201AD axial with 12.8 V standoff and 1500 W peak pulse — many manufacturers offer a 1.5KE12 or 1.5KE13A series part that will fit the same footprint and voltage window. Confirm the clamping voltage and breakdown tolerance against your protected rail margin before substituting.
