PMBT3904,215 NPN bipolar junction transistor
The PMBT3904,215 is a general-purpose NPN bipolar junction transistor (BJT) from Nexperia, housed in the compact SOT-23 surface-mount package. It is a widely used, industry-standard device known for its reliability and versatility in low-power switching and amplification applications. With a collector-emitter voltage of 40V and a continuous collector current of 200 mA, it is well-suited for a broad range of circuit functions in consumer electronics, embedded systems, and industrial controls. Its primary role is to function as a switch to control higher-power loads or as a small-signal amplifier to boost audio, radio, or digital signals.
This transistor offers a DC current gain (hFE) typically ranging from 100 to 300 at 10 mA, ensuring sufficient amplification. Key specifications include a low collector-emitter saturation voltage, which minimizes power loss when the transistor is used as a switch. The device supports a transition frequency (fT) of 300 MHz, making it suitable for high-frequency applications. Housed in the ubiquitous SOT-23 package, it is characterized for operation over a junction temperature range of -55°C to +150°C.
