BC81740MTF Description

Short technical summary and product information.

The BC81740MTF is an NPN silicon bipolar junction transistor manufactured by ON Semiconductor. It is designed for general-purpose switching and amplification applications. Key electrical specifications include a collector-emitter voltage (Vce) of 45V, a collector current (Ic) of 800mA, and a power dissipation of 310mW. The transistor offers a minimum DC current gain (hFE) of 250 at 100mA collector current and 1V Vce, with a maximum Vce saturation voltage of 700mV at 50mA base current and 500mA collector current. The transition frequency (fT) is 100MHz, making it suitable for low to moderate frequency circuits. The device is housed in a surface-mount SOT-23-3 package, which is compact and suitable for automated assembly. The maximum operating junction temperature is 150°C. The BC81740MTF is part of the BC817 series and is commonly used in portable electronics, driver stages, and signal processing circuits.
