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. 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.
-
4. What are key specifications to consider when selecting a BJT array?
Important parameters include collector current (Ic), voltage rating (Vce), hFE (current gain), and thermal resistance for reliability in operation.
