DMT3002LPS-13 Equivalent & Substitute Parts

Part Overview

The DMT3002LPS-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with 100A continuous drain current at Tc. This device is housed in a PowerDI5060-8 surface mount package and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with 964 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the application's thermal, voltage, and current requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMT3002LPS-13 is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a Vdss rating of 30V or greater to ensure safe operation within the application's voltage envelope.

Drain Current Capability: Substitute parts must support the required continuous drain current at the specified temperature condition (Tc). The DMT3002LPS-13 delivers 100A at Tc; substitute parts must meet or exceed this specification to maintain equivalent performance.

On-Resistance (RDS(on)): The on-resistance directly affects power dissipation and thermal performance. Substitute parts with comparable or lower RDS(on) values ensure thermal compatibility.

Gate Charge (Qg): Gate charge affects switching speed and driver requirements. Substitute parts with similar gate charge specifications maintain consistent switching characteristics.

Package and Mounting: All substitute parts must be surface mount devices compatible with the application's PCB layout and thermal management design.

Compliance and Status: All substitute parts must maintain active production status and equivalent RoHS and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

FDMS8018 (onsemi): This substitute part exceeds the continuous drain current requirement of the DMT3002LPS-13, delivering 120A at Tc compared to the main part's 100A. The FDMS8018 maintains equivalent voltage rating (30V), comparable on-resistance (1.8 mOhm), and lower gate charge (61 nC), which reduces switching losses. Both parts are active production devices with ROHS3 compliance and identical operating temperature ranges. The FDMS8018 is available in higher inventory (45,200 units) and is packaged in 8-PQFN (5x6) format.

FDMS0300S (onsemi): This substitute part is rated for 49A continuous drain current at Tc, which is below the DMT3002LPS-13 specification of 100A. The FDMS0300S maintains the 30V voltage rating and comparable on-resistance (1.8 mOhm) but exhibits higher gate charge (133 nC) and input capacitance (8705 pF). This part is suitable only for applications where the required drain current does not exceed 49A at Tc. Both parts maintain active production status, ROHS3 compliance, and identical operating temperature ranges. The FDMS0300S is available in higher inventory (18,826 units).

All substitute parts maintain AEC-Q101 or equivalent automotive-grade qualification, REACH compliance status, and moisture sensitivity level MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the FDMS8018 directly replace the DMT3002LPS-13 in all applications?

A: The FDMS8018 meets or exceeds all critical electrical parameters of the DMT3002LPS-13, including voltage rating, drain current capability, and on-resistance. However, the package type differs (8-PQFN versus PowerDI5060-8), which requires PCB layout verification to ensure thermal management and mechanical fit compatibility.

Q: What is the primary limitation of the FDMS0300S as a substitute?

A: The FDMS0300S is rated for 49A continuous drain current at Tc, which is significantly lower than the DMT3002LPS-13 specification of 100A. This part is suitable only for applications with reduced current requirements. The higher gate charge (133 nC) and input capacitance (8705 pF) may also affect switching performance compared to the main part.

Q: How do package differences affect substitution?

A: The DMT3002LPS-13 uses PowerDI5060-8 packaging, while both substitute parts use 8-PQFN (5x6) packaging. These packages have different thermal characteristics, footprints, and mounting requirements. PCB layout, thermal via placement, and heat dissipation paths must be re-evaluated when switching between package types.

Q: Are all substitute parts automotive-qualified?

A: The DMT3002LPS-13 carries AEC-Q101 qualification. The FDMS8018 and FDMS0300S are manufactured by onsemi and maintain active production status with equivalent compliance certifications (ROHS3, REACH Unaffected). Verification of specific automotive qualification requirements for your application is necessary.

Q: What is the impact of gate charge differences on circuit design?

A: The DMT3002LPS-13 has a gate charge of 77 nC at 10V. The FDMS8018 has lower gate charge (61 nC), which reduces switching losses and driver power requirements. The FDMS0300S has higher gate charge (133 nC), which increases switching losses and may require a more robust gate driver. Gate driver specifications must be verified for compatibility.

Q: Can thermal performance be maintained when substituting parts with different packages?

A: Thermal performance depends on package design, die size, and thermal interface properties. The DMT3002LPS-13 dissipates 136W at Tc, while the FDMS8018 dissipates 83W and the FDMS0300S dissipates 96W at Tc. Lower power dissipation in substitute parts may improve thermal performance, but PCB thermal design, copper area, and via placement must be re-evaluated for each package type.
