DMC2990UDJ-7

Overview

The DMC2990UDJ-7 is a complementary pair enhancement mode MOSFET manufactured by Diodes Incorporated. It integrates one N-channel and one P-channel device in an SOT963 package. The N-channel transistor provides a drain-source breakdown voltage of 20V, with a maximum on-resistance of 0.99Ω at VGS=4.5V and a continuous drain current of 450mA. The P-channel counterpart features a -20V breakdown voltage, a maximum on-resistance of 1.9Ω at VGS=-4.5V, and a continuous drain current of -310mA. Both channels operate within a junction temperature range of -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard part number includes a suffix indicating taping orientation. Confirm that the received component matches the required reel orientation for automated assembly equipment. Ensure compliance with RoHS directives and verify date codes if manufacturing history is relevant to the production timeline.

Selection Notes

Select this component for applications requiring a matched N/P channel pair in a minimal footprint. Evaluate thermal resistance and power dissipation limits under steady-state conditions. Consider the gate threshold voltage requirements relative to the driving logic levels. Verify that the package dimensions fit the available PCB space constraints.

Part Context

This component belongs to the DMC2990 series from Diodes Incorporated. It is designed as a complement pair to minimize on-state resistance while maintaining fast switching performance. The series targets high-efficiency power management applications where small form factors are critical.

Replacement Considerations

The DMC2990UDJ-7B is listed as an alternative part number within the same series. It utilizes the identical SOT963 case but may feature a different taping orientation. Verify mechanical compatibility before substitution.
