DMTH8012LPS-13 Equivalent & Substitute Parts

Part Overview

The DMTH8012LPS-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 80V drain-to-source voltage with 10A continuous drain current at 25°C (Ta) and 72A at case temperature (Tc). This device is housed in a 8-PowerTDFN surface mount package and is designed for power switching applications requiring efficient thermal management. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating application-specific constraints such as packaging availability, thermal requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMTH8012LPS-13 is determined by equivalence in the following critical parameters:

Voltage Rating: Both the main part and substitute must maintain the same 80V Vdss rating to ensure safe operation within the intended application voltage envelope.

FET Type and Technology: Both parts must be N-Channel MOSFETs using metal oxide technology to maintain functional compatibility with existing gate drive circuits and switching logic.

Package Type: Both parts utilize the 8-PowerTDFN surface mount package, ensuring mechanical and thermal interface compatibility with printed circuit board layouts.

Operating Temperature Range: The substitute part must support the full operating temperature range of -55°C to 175°C (TJ) to maintain reliability across all specified environmental conditions.

Compliance Standards: Both parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and supply chain requirements.

Continuous Drain Current: While the substitute may have different absolute current ratings, the electrical characteristics must remain within acceptable operating margins for the target application.

The FDMC86324 from onsemi meets these substitution criteria while offering alternative thermal and packaging characteristics within the PowerTDFN family.

Engineering Selection Recommendations

Primary Part Selection: The DMTH8012LPS-13 is the recommended primary selection for applications requiring the specified 80V, 10A continuous drain current performance with maximum thermal dissipation capability at case temperature (136W Tc). This part is in active production status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part Selection: The FDMC86324 serves as an equivalent substitute when supply constraints or packaging preferences necessitate an alternative source. Both parts share identical voltage ratings (80V Vdss), FET type (N-Channel), technology (MOSFET Metal Oxide), package form factor (8-PowerTDFN), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. Moisture sensitivity level remains at MSL 1 (unlimited) for both devices, eliminating moisture-related handling constraints.

Product Status: Both the DMTH8012LPS-13 and FDMC86324 maintain active production status, ensuring long-term availability and supply chain stability.

Temperature Range Limitation: The FDMC86324 operates to a maximum junction temperature of 150°C, compared to 175°C for the DMTH8012LPS-13. Applications requiring operation above 150°C junction temperature must retain the primary part selection.

Frequently Asked Questions (FAQ)

Q: Can the FDMC86324 directly replace the DMTH8012LPS-13 in all applications?

A: The FDMC86324 is electrically compatible for applications operating within its specified maximum junction temperature of 150°C. The primary part supports operation to 175°C. Applications requiring the full temperature range must use the DMTH8012LPS-13. Both parts share identical 80V voltage ratings, N-Channel FET type, and 8-PowerTDFN package form factor.

Q: What are the key differences between these two parts?

A: The primary differences are continuous drain current ratings (10A Ta / 72A Tc for DMTH8012LPS-13 versus 7A Ta / 20A Tc for FDMC86324), on-resistance characteristics (17 mOhm versus 23 mOhm at 10V), gate charge (34 nC versus 18 nC), and maximum operating temperature (175°C versus 150°C). Both maintain identical voltage ratings and package specifications.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both the DMTH8012LPS-13 and FDMC86324 are surface mount devices in the 8-PowerTDFN package, compatible with standard pick-and-place assembly processes and reflow soldering procedures.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Standard handling procedures apply to both devices.

Q: What is the significance of the different gate charge values?

A: The FDMC86324 exhibits lower gate charge (18 nC versus 34 nC), resulting in faster switching transitions and reduced gate drive power requirements. This characteristic may provide advantages in high-frequency switching applications, though both parts are functionally compatible with standard gate drive circuits.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DMTH8012LPS-13 and FDMC86324 maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for industrial and commercial applications.

Q: Which part should be selected for new designs?

A: The DMTH8012LPS-13 is the recommended selection for new designs requiring the full specified performance envelope, including maximum continuous drain current and extended temperature range to 175°C. The FDMC86324 is appropriate for applications with lower current requirements or when supply chain considerations necessitate an alternative source.
