BC547CTFR Description

Short technical summary and product information.

The BC547CTFR is a general-purpose NPN bipolar junction transistor manufactured by ON Semiconductor. It is designed for switching and amplification applications requiring moderate voltage and current handling.

 

Key electrical specifications include a collector-emitter voltage (Vce) of 45 V, a collector current rating of 100 mA, and a power dissipation of 500 mW. The DC current gain (hFE) is guaranteed at a minimum of 420 when tested at Ic=2 mA and Vce=5 V, ensuring consistent performance in linear operation. The transistor features a maximum Vce saturation voltage of 600 mV at Ib=5 mA and Ic=100 mA, and a transition frequency of 300 MHz, making it suitable for low-frequency amplification and switching circuits.

 

The device is housed in a through-hole TO-92-3 package (also known as TO-226-3, TO-226AA) with formed leads. It is rated for a maximum junction temperature of 150°C. The BC547CTFR is commonly used in consumer electronics, signal processing, and general-purpose switching applications.
