BC847BW

BC847BW Description

The BC847BW from Diotec Semiconductor is a high-performance NPN bipolar junction transistor (BJT) designed for surface-mount applications. With a collector-emitter breakdown voltage (Vce) of 45V and a maximum collector current (Ic) of 100mA, it is optimized for low-power amplification and switching tasks. The transistor boasts a transition frequency of 100MHz, making it suitable for high-frequency signal processing. Its low saturation voltage (600mV @ 5mA, 100mA) ensures efficient switching performance, while the high DC current gain (hFE ≥ 200 @ 2mA, 5V) guarantees reliable amplification in small-signal circuits. Packaged in bulk for cost-effective production, the BC847BW is ideal for compact, high-density PCB designs.
