Product details

Mosorb™ Zener – 1500 W peak pulse, DO-201AD axial

It clamps transients from an 8 V reverse standoff rail, with a breakdown voltage minimum of 9.4 V and a clamping ceiling of 15 V at peak current. The through-hole axial body (DO-201AD) suits point-to-point wiring or PCB mounting where a soldered lead absorbs mechanical strain better than a surface-mount package.

Obsolete – source through independent distribution

onsemi lists the 1N6374G as Obsolete. No official successor is published. For BOM lines that still call out this exact order code, independent distribution is the sourcing channel – we can quote against your quantity from available inventory or locate last-time-buy stock. The DO-201AD package and axial format are common across many Zener families, so a cross-reference search is worth the time if you are consolidating SKUs.

Voltage ratings and clamping margin

That 7 V window between standoff and clamp gives the downstream circuitry a defined transient suppression envelope.

Frequently asked questions

How can I order the 1N6374G or check stock?

The 1N6374G is obsolete per onsemi. We source it through independent distribution – submit an RFQ with your target quantity and we will confirm availability and current pricing at quote time. The DO-201AD axial package is common, so we can often locate stock from multiple sources.

What is the peak pulse power rating of the 1N6374G?

The 1N6374G is rated for 1500 W peak pulse power (1.5 kW) at 1 ms pulse width. That is the headline transient energy capability for this Mosorb™ Zener.
