MJB41C

Single Bipolar Transistors Overview

The onsemi MJB41C is a single NPN silicon power bipolar junction transistor (BJT) housed in a D2PAK-3 (TO-263) surface-mount package. It features a maximum collector-emitter voltage of 100V and a continuous collector current of 6A. The device has a total power dissipation rating of 2W at 25°C case temperature, with a transition frequency of 3MHz. It operates within a junction temperature range of -65°C to +150°C and includes an integrated thermal pad for efficient heat sinking.

Single Bipolar Transistors Feature Summary

• Single NPN configuration designed for general-purpose power switching and amplification applications.
• Low saturation voltage characteristics to minimize conduction losses during operation.
• Robust construction with ESD protection capabilities exceeding human model ratings.

Single Bipolar Transistors Applications

• Switching regulators and DC-DC converters
• Power amplifier output stages
• General-purpose high-current switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix (e.g., T4G, CT4G) against the datasheet to confirm packaging type and compliance status. Ensure the ordering part number matches the required lead time and moisture sensitivity level. Confirm RoHS and REACH declarations are current for the manufacturing site. Cross-reference the manufacturer's latest product change notification for any marking or assembly updates.

Single Bipolar Transistors Selection Notes

Select this component when a 100V NPN switch is required in a surface-mount form factor. Evaluate thermal management requirements carefully due to the 2W power dissipation limit without adequate heatsinking. Compare hFE gain ranges and VCE(sat) values against circuit drive capabilities. Consider the complementary PNP variant if push-pull configurations are needed.

Single Bipolar Transistors Part Context

The MJB41C belongs to the MJB series of plastic power transistors from onsemi. This series is characterized by low saturation voltages and fast switching speeds. It is often paired with its complementary PNP counterpart, the MJB42C, to form matched pairs for efficient push-pull amplifier designs.

Single Bipolar Transistors Replacement Considerations

Direct functional substitutes include the NJVMJB41CT4G for automotive-grade variants. Other compatible replacements may include similar 6A/100V NPN TO-263 devices from other manufacturers, provided pinouts and electrical parameters align.
