BD243CG Description

Short technical summary and product information.

The BD243CG is an NPN bipolar junction power transistor from onsemi, part of the complementary silicon plastic power transistor family. It is designed for general-purpose amplifier and switching applications. The device supports a maximum collector-emitter voltage (VCEO) of 100 V, a continuous collector current of 6 A, and a peak collector current of 10 A.

 

The transistor offers a minimum DC current gain (hFE) of 15 at IC = 3 A and 30 at IC = 0.3 A, both at VCE = 4 V. Maximum collector-emitter saturation voltage is 1.5 V at IC = 6 A and IB = 1 A. With a current-gain bandwidth product of 3 MHz, it is suitable for low-to-medium frequency amplification and switching circuits. Total device dissipation is 65 W at a case temperature of 25°C, derated at 0.52 W/°C above 25°C.

 

The BD243CG comes in a through-hole TO-220-3 package (supplier device package TO-220). Junction-to-case thermal resistance is 1.92 °C/W. The device operates and stores over a junction temperature range of -65°C to 150°C. Standard packaging is 50 units per rail.

 

The device is Pb-Free and RoHS3 compliant, making it suitable for lead-free soldering processes. Typical applications include general-purpose amplifier output stages, motor drivers, switching regulators, and other power switching circuits.
