DMC3730UVT-7

Overview

The DMC3730UVT-7 is a complementary pair enhancement mode MOSFET manufactured by Diodes Incorporated. It integrates an N-channel device (Q1) and a P-channel device (Q2) within a single TSOT26 package. The N-channel component provides a drain-source breakdown voltage of 25V, with maximum on-resistance values of 0.45Ω at VGS=4.5V, 0.60Ω at VGS=2.7V, and 0.73Ω at VGS=1.8V. The continuous drain current for the N-channel is 0.68A. The P-channel component features a -25V breakdown voltage, with maximum on-resistance values of 1.1Ω at VGS=-4.5V, 1.5Ω at VGS=-2.7V, and 2.2Ω at VGS=-1.8V. Its continuous drain current is rated at -0.46A.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Confirm RoHS compliance status and lead-free definitions directly from the manufacturer's quality documentation before procurement. Ensure the component meets AEC-Q101 reliability standards if automotive applications are intended.

Selection Notes

Select this component when space-constrained designs require both high-side and low-side switching capabilities in a single footprint. Evaluate the thermal resistance characteristics against the expected power dissipation requirements. Consider the gate threshold voltage ranges to ensure compatibility with the driving logic levels used in the target application circuit.
