DMN3020UFDF-13 Equivalent & Substitute Parts

Part Overview

The DMN3020UFDF-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with 15A continuous drain current at 25°C. This surface mount device is housed in a 6-UDFN package with exposed pad and is designed for general-purpose switching and amplification applications requiring moderate power dissipation up to 2.03W. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical characteristics, mechanical packaging, and compliance certifications remain identical across different manufacturing lots or date codes.

Substitute Part Grouping Explanation

Substitution of the DMN3020UFDF-13 is determined by strict equivalence across the following critical parameters:

Electrical Characteristics:

Drain-to-source voltage rating (Vdss): 30V
Continuous drain current (Id): 15A at 25°C
On-state resistance (Rds On): 19mOhm maximum at specified gate and drain conditions
Gate threshold voltage (Vgs(th)): 1V at 250µA
Gate charge (Qg): 27nC at 8V
Input capacitance (Ciss): 1304pF at 15V
Maximum power dissipation: 2.03W

Mechanical & Packaging Requirements:

Package designation: 6-UDFN Exposed Pad (U-DFN2020-6 Type F)
Mounting type: Surface Mount
Supplier device package: U-DFN2020-6 (Type F)

Compliance & Regulatory:

RoHS3 compliance
Moisture Sensitivity Level (MSL): 1 (Unlimited)
REACH status: Unaffected
Product status: Active

The DMN3020UFDF-7 qualifies as a parametric equivalent substitute because all electrical specifications, package dimensions, and compliance certifications are identical to the main part number.

Engineering Selection Recommendations

Both the DMN3020UFDF-13 and DMN3020UFDF-7 are Active products manufactured by Diodes Incorporated with identical electrical and mechanical specifications. Selection between these part numbers is based on availability and supply chain considerations rather than technical performance differences.

DMN3020UFDF-13 is suitable for applications where current inventory allocation or specific manufacturing lot traceability is required. Current inventory: 1177 pieces.

DMN3020UFDF-7 provides equivalent performance with higher current availability. Current inventory: 15738 pieces.

Both parts maintain full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), making them suitable for industrial, automotive, and consumer applications without additional handling restrictions. The identical package designation (6-UDFN Exposed Pad, U-DFN2020-6 Type F) ensures direct PCB layout compatibility and no redesign requirements for board-level integration.

Frequently Asked Questions (FAQ)

Q: Can DMN3020UFDF-7 be used as a direct replacement for DMN3020UFDF-13 without circuit modification?

A: Yes. All electrical parameters, including Vdss, Id, Rds On, gate charge, and input capacitance are identical. The package type, mounting method, and thermal characteristics are also identical. No circuit modifications are required.

Q: Are there any differences in gate drive requirements between these two part numbers?

A: No. Both parts have identical gate threshold voltage (Vgs(th) = 1V @ 250µA), maximum gate voltage (±12V), and gate charge specifications (27nC @ 8V). Gate drive circuits designed for one part number function identically with the other.

Q: Do these parts have the same thermal performance?

A: Yes. Maximum power dissipation is 2.03W (Ta) for both parts, and the operating temperature range is -55°C to 150°C (TJ) for both. Thermal management strategies remain unchanged between the two part numbers.

Q: Is the 6-UDFN package footprint identical between DMN3020UFDF-13 and DMN3020UFDF-7?

A: Yes. Both parts use the U-DFN2020-6 (Type F) package with exposed pad. PCB layouts, solder paste stencils, and pick-and-place programming require no modification when switching between these part numbers.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. No additional handling, storage, or documentation requirements differ between the two part numbers.

Q: What is the primary reason to select one part number over the other?

A: Availability and supply chain logistics. The DMN3020UFDF-7 has significantly higher current inventory (15738 pieces versus 1177 pieces), making it the preferred choice for high-volume production or time-sensitive procurement. Both parts are functionally and mechanically equivalent.
