BD242CG

BD242CG Description

The BD242CG from onsemi is a high-performance PNP bipolar junction transistor (BJT) designed for robust power amplification and switching applications. Housed in a TO-220 package, it offers a collector-emitter voltage (Vce) rating of 100V and a maximum collector current (Ic) of 3A, making it suitable for medium-power circuits. With a transition frequency of 3MHz, it balances speed and efficiency, while its low Vce saturation voltage (1.2V @ 600mA, 3A) ensures minimal power loss during operation. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.

BD242CG Features

• High Voltage Tolerance: 100V collector-emitter breakdown voltage for reliable operation in demanding environments.
• Low Saturation Voltage: 1.2V at 3A reduces heat dissipation and improves efficiency.
• High Current Handling: Supports up to 3A continuous collector current, ideal for power stages.
• DC Current Gain (hFE): Minimum 25 @ 1A, 4V, ensuring stable amplification.
• Through-Hole Mounting: TO-220 package facilitates easy heat sinking and mechanical stability.
• Robust Construction: MSL Not Applicable and EAR99 classification for broad industrial use.

BD242CG Applications

The BD242CG excels in:

• Power Amplifiers: Audio and RF stages requiring high-voltage PNP transistors.
• Linear Regulators: Efficient voltage regulation in power supplies.
• Motor Control: Driver circuits for DC motors and solenoids.
• Switching Loads: Relay drivers, inductive load switches, and automotive systems.
• Industrial Equipment: Robust performance in harsh environments due to high power dissipation (40W max).
