Overview
The DMC4040SSD-13 is a complementary pair enhancement mode MOSFET manufactured by Diodes Incorporated. It integrates one N-channel and one P-channel transistor within an 8-SOIC surface-mount package. The device supports a drain-source voltage of 40V and operates with a continuous drain current up to 5.1A for the N-channel and 7A for the P-channel. Maximum on-resistance values are specified at 24 mΩ for the N-channel and 45 mΩ for the P-channel. The component features a gate-source voltage rating of ±20V, a maximum power dissipation of 1.3W, and an operating temperature range from -55°C to +150°C.
Feature Summary
- Integrates complementary N-channel and P-channel enhancement mode MOSFETs in a single compact package
- Optimized for low on-resistance applications with specific Rds(on) ratings for each channel polarity
- Designed for surface-mount assembly using standard 8-SOIC footprint
Applications
- DC-DC converter synchronous rectification stages
- Motor control bridge circuits
- Power management load switches
Procurement Notes
Verify the exact suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required packaging format, such as reel or cut tape, as specified in the procurement documentation. Cross-reference the part number with official distributor catalogs to validate authenticity and current production status before finalizing purchase orders.
Selection Notes
Select this component when a matched complementary pair is required for 40V logic-level switching applications. Compare the specific on-resistance requirements of both channels against the 24 mΩ and 45 mΩ specifications. Confirm that the 1.3W power dissipation limit aligns with the thermal design constraints of the target PCB layout and ambient operating conditions.
Part Context
This part belongs to the DMC series of complementary MOSFET arrays produced by Diodes Incorporated. It shares the 8-SOIC package form factor with other devices in the family, such as the DMC4050SSD-13, but differs in specific electrical parameters like threshold voltage and on-resistance. The series is designed to simplify circuit design by replacing discrete dual-transistor solutions.
Replacement Considerations
The DMC4050SSD-13 is a related complementary pair in the same package family. Verify if the higher current ratings and different on-resistance values of the DMC4050 variant are acceptable for the specific application requirements.
