Substitute Part Grouping Explanation

Substitute parts for the DMT4008LFDF-13 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:

• Drain to Source Voltage (Vdss): 40V
• Continuous Drain Current (Id) @ 25°C: 11.8A
• On-State Resistance (Rds On) @ 10A, 10V: 9.5mOhm
• Power Dissipation (Max): 800mW
• Package Type: 6-UDFN Exposed Pad
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C
• RoHS Compliance: ROHS3 Compliant

Parts meeting all these specifications are classified as parametric equivalents and may be substituted without circuit redesign or thermal management modifications.
