概要
Description
BC816-16HR is a general-purpose small-signal transistor from the BC816 family, used for switching and amplification in low-power circuits. The “-16HR” suffix designates a specific gain class and a High-Reliability (HR) variant. Typical ratings (vary by manufacturer) include a collector-emitter voltage around 45 V, a collector current up to ~0.5 A, and a moderate current gain that depends on operating current and temperature. It is offered in common packages (SOT-23 for surface-mount or TO-92 for through-hole, depending on vendor). Applications include driver stages, signal amplification, and general switching. For exact electrical specs, pinout, and packaging, consult the supplier’s datasheet, as tolerances and packaging can differ between manufacturers.
