2SA733P

The 2SA733P is a PNP bipolar junction transistor designed for general-purpose amplification and switching applications. Manufactured by On Semiconductor, this device offers a collector-emitter breakdown voltage (Vceo) of 50V and a continuous collector current (Ic) rating of 500mA. With a DC current gain (hFE) of at least 200 at Ic=1mA and Vce=6V, it provides consistent amplification performance. The transistor has a transition frequency (ft) of 50MHz, making it suitable for low-frequency switching and audio amplification circuits. The maximum collector-emitter saturation voltage (Vce(sat)) is 300mV at Ib=10mA and Ic=100mA, ensuring low power loss in saturation. The device can dissipate up to 625mW of power and operates over a junction temperature range of -55°C to 150°C. It is housed in a TO-92-3 through-hole package, which is easy to mount on printed circuit boards. The 2SA733P is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited), making it suitable for lead-free soldering processes. This transistor is commonly used in audio preamplifiers, driver stages, and general-purpose switching circuits.
