Product details

1500W peak pulse power in a through-hole axial package

That 1500W rating tells you it can absorb a substantial transient without failing — useful for clamping surges on 48V or 53V rails in industrial or telecom gear. The DO-201AD axial package is a through-hole legacy footprint; it's robust for high-energy pulses but takes up more board area than a surface-mount alternative.

Voltage window and unidirectional clamping

Reverse standoff voltage is 53V, breakdown minimum is 58.9V, and clamping at peak pulse current is 85V max. This window means the diode stays off below 53V, starts conducting around 59V, and holds the line to 85V under full surge — a tight enough clamp to protect a 60V-rated downstream device. It is a single unidirectional channel, so polarity matters on the board.

onsemi lists the 1N6290A as Obsolete.

Temperature range and storage considerations

Frequently asked questions

How can I order the 1N6290A or request a quote?

The 1N6290A is obsolete per onsemi, so we source it through our independent supply network. Submit an RFQ with your target quantity and target price; we confirm availability and current pricing at quote time. No stock-holding claim — every order is sourced to your BOM line.

What is the difference between 1N6290A and 1N6290?

The 'A' suffix typically indicates a tighter tolerance on breakdown voltage, but the evidence does not carry the exact delta. For fit, both share the same DO-201AD package and 1500W rating; confirm the breakdown voltage tolerance from the respective datasheets before substituting.
