Engineering Selection Recommendations

Both the DMN2024UQ-13 and DMN2024UQ-7 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is determined by packaging configuration and inventory availability rather than performance differentiation. The DMN2024UQ-13 is supplied in Tape & Reel (TR) packaging designated as "1," while the DMN2024UQ-7 is supplied in Tape & Reel (TR) packaging designated as "3." Both devices maintain automotive-grade qualification under AEC-Q101 and comply with ROHS3 and REACH regulatory requirements. Component selection should be based on supply chain requirements, reel configuration compatibility with assembly equipment, and current inventory status.

Frequently Asked Questions (FAQ)

Q: Can the DMN2024UQ-7 be used as a direct replacement for the DMN2024UQ-13?

A: Yes. Both parts are electrically and mechanically identical N-Channel MOSFETs with matching Vdss (20V), drain current (6.8A), on-resistance (25mOhm), and power dissipation (800mW). Both are packaged in SOT-23-3 and carry AEC-Q101 automotive qualification. The difference lies in tape reel configuration (TR-1 versus TR-3), which affects assembly line compatibility but not device performance.

Q: Are there any differences in thermal or electrical performance between these parts?

A: No. The DMN2024UQ-13 and DMN2024UQ-7 share identical electrical characteristics, including operating temperature range (-55°C to 150°C), gate threshold voltage (900mV @ 250µA), and input capacitance (647pF @ 10V). Thermal performance is equivalent due to identical power dissipation ratings (800mW) and package geometry.

Q: What is the significance of the TR-1 and TR-3 designations?

A: The TR-1 and TR-3 designations refer to different tape reel configurations used for automated assembly. TR-1 and TR-3 indicate different reel sizes or component spacing on the tape. Selection depends on compatibility with your specific pick-and-place assembly equipment. Electrical and mechanical performance is unaffected by this designation.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the DMN2024UQ-13 and DMN2024UQ-7 carry automotive-grade classification and AEC-Q101 qualification, confirming suitability for automotive circuit applications. Both comply with ROHS3 and REACH regulatory standards.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use the identical SOT-23-3 package footprint (also designated TO-236-3 or SC-59). PCB layouts, solder pad dimensions, and component placement are interchangeable. No design modifications are required when substituting between these parts.

Q: What is the difference in inventory availability?

A: The DMN2024UQ-13 has 873 pieces in stock, while the DMN2024UQ-7 has 2800 pieces in stock. Selection may be influenced by delivery timeline and quantity requirements.
