A733 Specs and Replacement
The A733 is a PNP bipolar junction transistor widely used in low-frequency analog circuits. Designed for general-purpose signal processing, it provides reliable performance in amplification and switching applications. The device typically operates with a collector-emitter voltage of 50V and a collector current up to 150mA, making it suitable for small-signal stages in audio equipment, sensor interfaces, bias control networks. Its DC current gain ranges roughly from 120 to 600, depending on the specific grade, ensuring stable gain in low-noise environments. The transistor's low saturation voltage and modest noise figure contribute to efficient amplification in compact designs. Packaged commonly in TO92/SOT23, the A733 offers straightforward PCB integration and good thermal behavior for its size.
