Discrete Semiconductors

Discrete semiconductors — 12 profiles of MOSFETs, bipolar transistors and diodes (switching, Schottky, TVS, rectifier) — do the raw switching, rectification and protection work in power and signal paths. Voltage and current ratings, on-resistance or forward drop, and package thermal performance are the interchange criteria; match the datasheet electrical tables, not just the package, before approving a cross. Confirm the full ordering code, since suffixes change packing, grade or automotive qualification.

Sourcing notes for Discrete Semiconductors. Start from the exact manufacturer part number: similar-sounding parts across vendors are rarely interchangeable, and parametric differences hide in the datasheet electrical tables. Confirm package, pinout and grade against the datasheet before requesting a quote, and check lifecycle status for anything headed into a long production run — line up a second source early for allocated or single-source lines. Always request traceability documents (date code, lot code, original packing) and confirm the inspection process applied to your lot.
