Discretes
Power discretes, MOSFETs, IGBTs, diodes, small-signal transistors.
Lead-time range, Dec 2025 – Oct 2026 Reading the chartsThe shaded band is the lead-time range in weeks; the line is its midpoint. A red triangle marks an open-ended “52+” month.
The colored strip shows each month’s status. Gaps are months the category wasn’t reported.
Numbered dots are dated market events. They are listed under the chart on each category page.

Monthly status Status scale1 Stable: normal lead times, predictable supply.
2 Watch: early signals such as rising prices or stretching in some families. Monitor.
3 Alert: lead times stretching or selective allocation. Check exposed parts on your BOM.
4 Critical: broad allocation or severe extension. Plan around constraint.
The status is the analyst’s judgment, informed by the sources. It is not a formula.
