The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. [1][2][3] It is designed for low current and power, medium voltage, and can operate at moderately high speeds. It …

This device is designed as a general−purpose amplifier and switch. The useful dynamic range extends to 100 mA as a switch and to 100 MHz as an amplifier. Stresses exceeding those listed in the Maximum Ratings table may damage the device.

2024年3月23日 · 2N3904 is complementary to 2N3906 PNP bipolar junction transistor. It has a current rating of 200 mA, a voltage rating of 40 V, and a power rating of 625 mW. And provides a current gain of 100 when the current of 10 mA flows through the collector. 2N3N04 is popular due to its high gain and low saturation voltage.

2017年6月15日 · The 2N3904 is an extremely popular NPN transistor that is used as a simple electronic switch or amplifier that can handle 200 mA (absolute maximum) and frequencies as high as 100 MHz when used as an amplifier.

2017年11月23日 · 2N3904 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N3904 has a gain value of 300; this value determines the amplification capacity of the transistor. The maximum amount of current that could ...
