DMN3028L-7 Equivalent & Substitute Parts

Part Overview

The DMN3028L-7 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 30 V drain-to-source voltage with a continuous drain current of 6.2 A at 25°C. This device is housed in a SOT-23-3 surface mount package and is designed for general-purpose switching and amplification applications in low-voltage circuits. The part is currently in active production status with 12,700 units available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the same package type and thermal specifications. Identifying alternative sources ensures design flexibility, supply chain continuity, and access to devices with extended qualification or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitution of the DMN3028L-7 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Drain-to-Source Voltage (Vdss): 30 V
Continuous Drain Current (Id) @ 25°C: 6.2 A
On-State Resistance (Rds On) @ 4A, 10V: 25 mOhm
Gate Threshold Voltage (Vgs(th)) @ 250µA: 1.8 V
Gate Charge (Qg) @ 10V: 10.9 nC
Input Capacitance (Ciss) @ 15V: 680 pF
Power Dissipation (Max): 860 mW
Operating Temperature Range: -55°C to 150°C

Mechanical Equivalence Criteria:

Package Type: SOT-23-3 (TO-236-3, SC-59)
Mounting Type: Surface Mount
FET Type: N-Channel
Technology: MOSFET (Metal Oxide)

The DMN3028LQ-7 meets all electrical and mechanical equivalence criteria and is therefore classified as a parametric equivalent. The primary distinction is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and automotive-grade qualification (AEC-Q101).

Engineering Selection Recommendations

DMN3028L-7 (Standard Grade)

The DMN3028L-7 is suitable for general-purpose applications where standard industrial compliance is required. The device is ROHS3 compliant and REACH unaffected. This part is recommended for consumer electronics, industrial control circuits, and non-automotive switching applications where AEC-Q101 qualification is not mandated.

DMN3028LQ-7 (Automotive Grade)

The DMN3028LQ-7 is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. This part is suitable for automotive applications, industrial systems requiring enhanced reliability, and designs where automotive-level component qualification is specified. The electrical and thermal performance is identical to the standard-grade DMN3028L-7. The primary difference is the packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and automotive qualification status.

Both parts are manufactured by Diodes Incorporated and maintain active production status. Selection between these parts depends on application requirements and supply chain preferences regarding packaging format and qualification level.

Frequently Asked Questions (FAQ)

Q: Can the DMN3028LQ-7 be used as a direct replacement for the DMN3028L-7?

A: Yes. The DMN3028LQ-7 is electrically and mechanically equivalent to the DMN3028L-7. All electrical parameters, including Vdss, Id, Rds On, gate charge, and input capacitance, are identical. Both devices use the SOT-23-3 package and surface mount technology. The primary differences are packaging format and automotive-grade qualification.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is a continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel® provides flexibility for lower-volume orders and mixed-component picking. Both formats contain the same device in the same SOT-23-3 package. The choice depends on production volume and assembly equipment compatibility.

Q: Is the DMN3028LQ-7 suitable for automotive applications?

A: Yes. The DMN3028LQ-7 carries AEC-Q101 automotive qualification, making it suitable for automotive and automotive-grade industrial applications. The DMN3028L-7 does not carry this qualification and is not recommended for applications requiring automotive-level component certification.

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

A: No. Both the DMN3028L-7 and DMN3028LQ-7 have identical power dissipation ratings (860 mW) and operating temperature ranges (-55°C to 150°C). Thermal performance is equivalent.

Q: What is the base product number for these parts?

A: The base product number is DMN3028. Both the DMN3028L-7 and DMN3028LQ-7 are variants of this base product, differentiated by packaging format and qualification level.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DMN3028L-7 and DMN3028LQ-7 are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.
