What:
available bipolar transistor packages

Direction:
depends on application

Surface mount (SMT) compatibility is a requirement for most volume assembly applications. Plastic packages limit maximum junction temperatures to 150 C vs 200 C for other packages, so may limit performance of power products. Ceramic or hermetic packages are typically required for hi-rel applications, and typically offer better performance through reduced parasitics. Packages with high parasitic inductance and/or capacitance (typically plastic packages) may severely limit device performance at higher frequencies (above 2 GHz).

Range:

SMT (surface mount)
Surface mount packages have co-planer leads that allow for device mounting without the use of through holes. Surface mount capability is generally considered to be a requirement for automated assembly.
