Product details

The 1N6287A: For BOM positions that require this exact MPN, sourcing runs through independent distribution. Availability and pricing are confirmed at RFQ time against the required quantity.

44.7V breakdown, 64.8V clamp — a 40V rail protector

The 1N6287A is a unidirectional Zener TVS diode from the Mosorb™ series, rated for 1500 W peak pulse power. The reverse standoff voltage is 40.2 V, breakdown minimum is 44.7 V, and clamping at peak pulse current is 64.8 V. The axial package (through-hole) supports board-level replacement and rework without special profile equipment. Operating temperature spans -65°C to 175°C, suiting extreme environments.

Peak pulse power and clamping margin

The 1500 W peak pulse rating defines the surge energy the diode can absorb. The 64.8 V clamp sets the voltage seen by downstream circuitry during an event. No power line protection feature is listed — this is a general-purpose transient suppressor, not a dedicated rail comb clamp.

Frequently asked questions

How can I order 1N6287A or check stock?

1N6287A is obsolete — onsemi no longer manufactures it. Sourcing runs through independent distribution; we can source and quote it to order against your BOM quantity. Confirm availability and current pricing at quote time.
