DMN3028LQ-13 Equivalent & Substitute Parts

Part Overview

The DMN3028LQ-13 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 qualified to AEC-Q101 automotive standards. The part is actively produced and maintains ROHS3 compliance with REACH unaffected status.

Substitute parts are identified when electrical characteristics, mechanical packaging, and operational ratings remain equivalent across the device family. The DMN3028LQ-13 is supplied in Tape & Reel (TR) packaging; alternative packaging formats of the same base device may be required for different procurement or assembly workflows.

Engineering Selection Recommendations

The DMN3028LQ-13 and DMN3028LQ-7 are electrically and mechanically equivalent N-Channel MOSFETs from Diodes Incorporated. Both devices meet AEC-Q101 automotive qualification requirements and maintain ROHS3 compliance. Selection between these parts is determined by packaging and supply chain requirements:

DMN3028LQ-13 is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations where continuous reel feeding is standard.

DMN3028LQ-7 is supplied in Cut Tape (CT) and Digi-Reel® format, appropriate for lower-volume applications, mixed component kits, or procurement workflows requiring alternative packaging configurations.

Both parts share identical electrical performance, thermal characteristics, and regulatory compliance. Substitution between these variants does not alter circuit behavior or reliability when used within specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Are the DMN3028LQ-13 and DMN3028LQ-7 electrically identical?

A: Yes. Both devices are N-Channel MOSFETs with identical electrical specifications: 30 V Vdss, 6.2 A continuous drain current, 25 mOhm Rds On, and 860 mW power dissipation. All switching characteristics, gate charge, and capacitance parameters are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The DMN3028LQ-13 is supplied in Tape & Reel (TR) format, while the DMN3028LQ-7 is supplied in Cut Tape (CT) and Digi-Reel® format. The physical device and electrical performance remain unchanged.

Q: Can I substitute DMN3028LQ-7 for DMN3028LQ-13 in my design?

A: Yes, from an electrical and thermal standpoint. Both parts are AEC-Q101 qualified, automotive-grade MOSFETs with identical SOT-23-3 package dimensions and pinout. Substitution is valid for circuit operation. Verify that your assembly process accommodates the alternative packaging format.

Q: Are both parts still in active production?

A: Yes. Both the DMN3028LQ-13 and DMN3028LQ-7 maintain Active product status with Diodes Incorporated.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both devices are automotive-grade, AEC-Q101 qualified, ROHS3 compliant, and REACH unaffected. They are suitable for automotive applications requiring these certifications.

Q: What is the SOT-23-3 package?

A: SOT-23-3 is a three-pin surface mount package, also designated as TO-236-3 or SC-59. It is a standard small-outline transistor package widely used for discrete MOSFETs and other semiconductor devices.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel and Cut Tape formats are supply and assembly logistics variations. The physical device, electrical characteristics, and performance are identical.

Q: What is Digi-Reel® packaging?

A: Digi-Reel® is a proprietary packaging format offered by certain distributors as an alternative to standard tape and reel. It provides the same component in a different supply configuration suitable for specific procurement workflows.
