1. What advantages do BJT arrays offer over single transistors?
BJT arrays provide better matching between transistors, reduce PCB space, and improve thermal performance since all transistors share the same substrate.
-
2. What packages are BJT arrays available in?
Common packages include surface-mount types like SC-88, SOT-363, or TSSOP, which are compact and suitable for space-constrained designs.
-
3. What are the limitations of BJT arrays?
While they save space, they can limit flexibility if specific transistor types or configurations are needed. Also, thermal coupling might not always be beneficial in all scenarios.
-
4. Are there specific applications for dual BJT arrays?
Dual BJT arrays are commonly used in push-pull amplifier stages, LED drivers, or signal switching circuits.
