1. What are BJT arrays used for?
BJT arrays are often used in analog circuits like amplifiers, switches, and oscillators where matched transistor pairs are required for balanced performance.
-
2. 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.
-
3. What is a pre-biased BJT array?
Pre-biased arrays have integrated resistors, simplifying circuit design and reducing external component count, ideal for switching or logic applications.
-
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.
