Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMN7022LFG-13 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel topology must be maintained
• Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 75V
• Continuous Drain Current (Id): Substitute must support the required current level
• On-Resistance (Rds On): Lower or equivalent values ensure thermal performance
• Gate Threshold Voltage (Vgs(th)): Must fall within compatible drive voltage ranges
• Gate Charge (Qg): Lower values reduce switching losses
• Input Capacitance (Ciss): Lower values improve switching speed
• Operating Temperature Range: Must encompass the application's thermal requirements

Mechanical Compatibility Criteria:

• Package Type: 8-PowerVDFN form factor required for PCB layout compatibility
• Mounting Type: Surface mount configuration must be maintained
• Supplier Device Package: PowerDI3333-8 package family

Compliance Criteria:

• RoHS3 Compliance: All substitutes must maintain regulatory compliance
• REACH Status: Unaffected status required

Two substitute parts are identified: DMN7022LFG-7 (parametric equivalent) and DMTH8028LFVW-13 (manufacturer-recommended upgrade).

Parameter Comparison

Engineering Selection Recommendations

DMN7022LFG-7 (Parametric Equivalent)

The DMN7022LFG-7 is a parametric equivalent to the DMN7022LFG-13, sharing identical electrical specifications including 75V Vdss, 7.8A continuous drain current, 22mOhm on-resistance, and 900mW power dissipation. Both devices are classified as obsolete. The primary distinction is packaging format: DMN7022LFG-7 is supplied in Tape & Reel (TR) configuration, whereas DMN7022LFG-13 uses standard packaging. This substitute is suitable for applications requiring identical electrical performance and thermal characteristics. Inventory availability is significantly higher for DMN7022LFG-7 (35,553 pieces versus 9,155 pieces).

DMTH8028LFVW-13 (Manufacturer-Recommended Upgrade)

The DMTH8028LFVW-13 is the manufacturer-recommended substitute, offering enhanced performance characteristics while maintaining package compatibility. Key advantages include:

• Higher Vdss rating (80V versus 75V) provides increased voltage margin
• Significantly higher continuous drain current (27A versus 7.8A) enables higher power handling
• Reduced gate charge (10.4nC versus 56.5nC) improves switching efficiency
• Lower input capacitance (631pF versus 2737pF) reduces switching losses
• Extended operating temperature range (-55°C to 175°C versus -55°C to 150°C)
• Higher power dissipation capability (1.5W versus 900mW)
• Active product status ensures long-term availability and supply continuity
• Wettable flank feature improves solder joint reliability

The DMTH8028LFVW-13 is suitable for new designs and applications requiring enhanced thermal performance or higher current capacity. This part is recommended for production continuity given the obsolete status of the original part.

Both substitutes maintain ROHS3 compliance, REACH unaffected status, and 8-PowerVDFN package compatibility.

Frequently Asked Questions (FAQ)

Q: Can DMN7022LFG-7 be used as a direct replacement for DMN7022LFG-13?

A: Yes. The DMN7022LFG-7 is a parametric equivalent with identical electrical specifications. The difference is packaging format (Tape & Reel versus standard packaging). Both parts are obsolete and share the same electrical performance characteristics, on-resistance, gate charge, and power dissipation ratings.

Q: What are the advantages of using DMTH8028LFVW-13 over DMN7022LFG-13?

A: The DMTH8028LFVW-13 offers multiple performance improvements: higher voltage rating (80V), significantly higher current capacity (27A), reduced gate charge (10.4nC), lower input capacitance (631pF), extended temperature range (175°C maximum), and higher power dissipation (1.5W). Additionally, it is an active product with assured long-term availability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-PowerVDFN package type, ensuring identical pinout and PCB layout compatibility. The Wettable Flank feature on DMTH8028LFVW-13 is a manufacturing enhancement that does not affect electrical or mechanical compatibility.

Q: What is the significance of the "Wettable Flank" feature on DMTH8028LFVW-13?

A: Wettable Flank is a manufacturing enhancement that improves solder joint visibility and reliability during assembly inspection. It does not affect electrical performance or thermal characteristics but provides improved manufacturing process control.

Q: Why is DMTH8028LFVW-13 recommended despite higher specifications?

A: Higher specifications provide design margin and improved reliability. The 80V Vdss rating offers protection against voltage transients. Higher current capacity (27A) reduces thermal stress at the same operating point. Lower gate charge and input capacitance improve switching efficiency. Extended temperature range accommodates wider application environments. The active product status ensures supply continuity and technical support.

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

A: DMTH8028LFVW-13 has higher power dissipation capability (1.5W versus 900mW) and extended maximum junction temperature (175°C versus 150°C). At equivalent current levels, the lower on-resistance (25mOhm at 5A versus 22mOhm at 7.2A) and higher power rating provide improved thermal headroom.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant and REACH unaffected. These certifications ensure regulatory compliance for industrial and consumer applications across multiple jurisdictions.

Q: Can DMTH8028LFVW-13 be used in existing designs without circuit modification?

A: Yes. The higher electrical ratings and improved performance characteristics of DMTH8028LFVW-13 are backward-compatible with designs using DMN7022LFG-13. No circuit modifications are required. The identical package and pinout ensure direct PCB compatibility.
