MJD6039T4

Single Bipolar Transistors Overview

The MJD6039T4G is a single NPN bipolar power Darlington transistor manufactured by onsemi. It features an 80 V collector-emitter voltage (VCEO) and a 5 V emitter-base voltage (VEBO). The device supports a maximum DC collector current of 4 A and a power dissipation of 20 W. It operates within a temperature range of -65 °C to +150 °C. The component is housed in a TO-252-3 (DPAK) surface-mount package.

Single Bipolar Transistors Feature Summary

• High current gain capability suitable for driving loads with minimal base drive current
• Robust thermal performance allowing operation up to 150 °C junction temperature
• Integrated ESD protection structure for enhanced reliability

Single Bipolar Transistors Applications

• DC motor control circuits
• Relay driver interfaces
• Power switching applications requiring high input impedance

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official documentation, as 'MJD6039T4' may differ from the verified 'MJD6039T4G'. Confirm RoHS compliance status via the manufacturer's latest datasheet. Ensure the ordering quantity matches the reel specifications provided in the official product data sheet.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN switch is required for moderate power levels. The DPAK package offers a balance between thermal management and PCB space efficiency. Consider the 80 V rating for low-voltage DC systems. Verify that the 4 A continuous current limit meets the load requirements without excessive heat sinking.

Single Bipolar Transistors Part Context

This part belongs to the MJD6039 series of power Darlington transistors. It serves as a surface-mount alternative to through-hole variants like the 2N6039G. The series is designed for general-purpose power switching where high current gain is beneficial. It complements onsemi's broader portfolio of discrete semiconductor devices.

Single Bipolar Transistors Replacement Considerations

The 2N6039G is a pin-compatible through-hole replacement. Verify package differences and thermal resistance values before substitution. Ensure the replacement part meets the same voltage and current ratings for equivalent circuit performance.
