DMC3350LDWQ-7

Overview

The DMC3350LDWQ-7 is a complementary pair enhancement mode MOSFET array manufactured by Diodes Incorporated. It integrates an N-channel and a P-channel device within a compact SOT-363 surface-mount package. The component features a drain-source voltage rating of 30V for both channels. Continuous drain current capabilities are specified at 900mA for the N-channel and 600mA for the P-channel under ambient temperature conditions. The total power dissipation is rated at 350mW. This configuration supports efficient switching applications requiring minimal board space.

Feature Summary

• Integrates complementary N-channel and P-channel enhancement mode MOSFETs in a single package
• Provides low profile surface mount packaging suitable for space-constrained designs
• Supports bidirectional switching configurations through integrated complementary pairs

Applications

• DC-DC converter input protection circuits
• Battery management system load switches
• Portable electronic device power distribution

Procurement Notes

Verify the specific ordering suffix to ensure correct tape and reel quantity specifications, as variations exist between standard and bulk packaging options. Confirm that the SOT-363 footprint matches your PCB layout requirements. Cross-reference the manufacturer datasheet for thermal derating curves relevant to your operating environment. Ensure compliance with RoHS directives if required for your final assembly process.

Selection Notes

Select this component when a matched N/P channel pair is required for synchronous rectification or high-side/low-side driving. Evaluate the 30V voltage rating against your circuit's maximum transient voltages. Consider the 350mW power dissipation limit relative to your thermal management strategy. The SOT-363 package offers a smaller footprint compared to discrete dual packages, aiding in miniaturization efforts.

Part Context

This part belongs to Diodes Incorporated's portfolio of complementary MOSFET arrays designed for portable electronics. These devices are engineered to replace discrete transistor pairs, reducing component count and assembly time. The series typically targets applications where space efficiency and switching performance are critical constraints in consumer and industrial hardware design.

Replacement Considerations

Direct substitutes include other 30V complementary MOSFET arrays in SOT-363 packages from various manufacturers. Verify pinout compatibility and electrical parameters such as Rds(on) and threshold voltage before substitution. Ensure the replacement device meets the same thermal and voltage ratings to maintain circuit integrity.
