Description:
The MBT3946 is a versatile bipolar junction transistor (BJT) capable of operating in both NPN and PNP configurations, offering flexibility in various circuit designs. With a maximum collector-emitter voltage (Vceo) of 40V and a collector current (Ic) rating of 200mA, it is suitable for low-power applications where moderate voltage and current handling are required. The transistor is designed to dissipate up to 150mW of power (Pd) and operates efficiently at frequencies up to 300MHz (fT), making it suitable for applications requiring high-frequency performance.

Features:

● Type: NPN/PNP
● Vceo: 40V
● Ic: 200mA
● Power Dissipation (Pd): 150mW
● Transition Frequency (fT): 300MHz, ideal for applications requiring high-speed switching and amplification.
● Versatile Configuration: Can be used as either an NPN or PNP transistor, offering flexibility in circuit design and integration.
● Compact Design: Suitable for space-constrained applications due to its small form factor and low power dissipation.

Applications:
The MBT3946 transistor finds application in a wide range of electronic circuits, including:
