Product details

1500W Zener TVS in DO-201AD axial

The 1N6291ARL4 is a unidirectional Zener TVS diode from onsemi's Mosorb™ series, rated for 1500W peak pulse power at 1ms. It clamps at 92V max with a 58.1V reverse standoff, making it a fit for 48V-60V rail protection in industrial and telecom gear.

Obsolete — sourcing through independent channels

onsemi lists the 1N6291ARL4 as Obsolete. For BOM lines needing this exact order code, supply is limited to existing distributor and broker inventory — sourced per RFQ against the required quantity.

Breakdown and clamping for 58V rails

Minimum breakdown voltage is 64.6V, clamping at 92V at peak pulse current. The 1500W rating gives a 16A Ipp margin on a 58V nominal rail — enough for secondary surge protection in AC-DC stages or DC bus inputs.

Frequently asked questions

How can I order 1N6291ARL4 or check stock?

The 1N6291ARL4 is obsolete per onsemi. We source it through our independent supply network — submit an RFQ with your target quantity for a current availability and price check. No stock-holding claim is made; every quote is order-specific.

Is 1N6291ARL4 a Zener diode or a TVS diode?

It is a Zener-type TVS diode — the Mosorb™ series uses Zener avalanche technology for transient suppression. The listed type is Zener, and it is applied as a unidirectional TVS clamp.

What is the difference between 1N6291ARL4 and 1N6291A?

The 1N6291ARL4 suffix indicates Tape & Reel packaging. The 1N6291A base part shares the same electrical ratings (58.1V standoff, 64.6V breakdown, 92V clamp, 1500W). The only difference is the reel format — the ARL4 variant is supplied on tape for automated insertion.
