DMT3003LFGQ-7 Equivalent & Substitute Parts

Part Overview

The DMT3003LFGQ-7 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with 22A continuous drain current at 25°C (Ta) and 100A at case temperature (Tc). This device is housed in an 8-PowerVDFN surface mount package and is qualified to AEC-Q101 automotive standards. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or manufacturing discontinuation. The substitute parts listed maintain electrical and mechanical equivalence to ensure direct replacement capability in existing designs without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the DMT3003LFGQ-7 are derived from the same base product family (DMT3003) and maintain identical electrical specifications across all critical parameters. Substitution is determined by the following key parameters:

Electrical Equivalence Criteria:

• Drain-to-Source Voltage (Vdss): 30V
• Continuous Drain Current (Id): 22A (Ta), 100A (Tc)
• On-Resistance (Rds On): 3.2 mOhm @ 20A, 10V
• Gate Threshold Voltage (Vgs(th)): 3V @ 250µA
• Gate Charge (Qg): 44 nC @ 10V
• Input Capacitance (Ciss): 2370 pF @ 15V
• Maximum Gate Voltage (Vgs): ±20V
• Power Dissipation: 2.4W (Ta), 62W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical & Compliance Equivalence Criteria:

• Package Type: 8-PowerVDFN
• Mounting Type: Surface Mount
• Packaging Format: Tape & Reel (TR)
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts differ only in manufacturing date code designations (suffix -7, -13, or -Q designation) and inventory availability. These designations do not affect electrical performance or mechanical compatibility.
