Discrete transistors and diodes are commonplace in electronic designs and are used throughout applications for small signal to high power requirements and over DC to RF/Microwave signal rates. With devices typically having multiple sources and a current environment of relaxed lead times, these components are often taken for granted and seen as a “commodity.” However, the inability to purchase a single discrete component can halt production as easily as the main microprocessor.

Like most electronics, the technology and packaging of discrete components continually evolve, leaving some products with limited sources as they age. Extensive planning and qualification efforts may be necessary for potential alternatives. When possible, the best option is sourcing original components.

In the current market environment, lead times are relatively short. As a reaction, many distributors and suppliers have reduced available inventory. This has a limited impact unless it is a part of your bill of materials that has been removed from the in-stock inventory.

Rochester Electronics considers long-term market needs, not just momentary highs and lows. The market is currently steady, but history and industry experts show this can change abruptly. To prepare and support our customers, Rochester has proactively strengthened key product inventory, including a significant increase in our discrete product portfolio. Our selection covers obsolete and active lifecycle devices, including newer SiC and GaN technologies, and many proprietary packaged devices, such as those used in RF power amplifiers and IGBT power modules.

Rochester’s 100% authorized, traceable, and guaranteed inventory is sourced from top industry suppliers, including onsemi, Infineon, Nexperia, and Renesas.
