➀ Nexperia has introduced 20 bipolar power transistors in the 2 x 2mm DFN2020D-3 package, with half being automotive-qualified. ➁ These transistors range from 50 to 80V ratings and 1 to 3A currents, with both npn and pnp types available. ➂ The DFN2020D-3 package offers an 80% reduction in board space compared to SOT89 and a 90% reduction compared to SOT223, featuring side-wettable flanks for automated optical inspection.

➀ The article reviews a free handbook on bipolar junction transistors by Nexperia, which requires providing personal details for download. ➁ The handbook covers a wide range of topics from basic physics to practical circuit applications. ➂ The author highly recommends the book, despite its Nexperia-centric focus.
