Product details

It clamps transients on a 15.3V nominal rail to 25.2V maximum, protecting downstream semiconductors from surges caused by load dump, inductive kickback, or lightning coupling in general-purpose industrial and telecom equipment.

Obsolete — sourcing options for the 1N6277A

onsemi lists the 1N6277A as Obsolete. For a BOM line that must be filled, we source this part to order against your quantity — confirm the required date-code range and volume, and we will quote from available inventory or broker channels. The DO-201AD axial package is through-hole.

Key ratings that define the protection window

The reverse standoff voltage is 15.3V — the rail should never exceed this during normal operation. Breakdown occurs at a minimum of 17.1V, and the clamping voltage at peak pulse current is 25.2V maximum.

Frequently asked questions

Is 1N6277A obsolete or still active?

Buyers need to know lifecycle status to decide if they should redesign or seek replacements.

What is the direct replacement for 1N6277A?

Critical for sourcing when the original is obsolete; ensures continuity in the BOM.

What are the specifications of 1N6277A?

Design engineers must verify peak power, voltage, and package fit before using the part.

Where can I buy 1N6277A and is it in stock?

Buyers need to check real-time availability and lead times to avoid production delays.

What is the cross reference for 1N6277A?

Allows comparison with equivalent parts from other brands for alternate sourcing.

What is the price of 1N6277A?

Budgeting and BOM cost estimation require current pricing from multiple distributors.
