ATP108-TL-H Equivalent & Substitute Parts

Part Overview

The ATP108-TL-H is a P-Channel MOSFET manufactured by onsemi, rated for 40V drain-to-source voltage with 70A continuous drain current in ATPAK surface mount packaging. This device is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating different package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATP108-TL-H is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 40V
• Continuous Drain Current (Id): Must support minimum 70A at rated conditions
• On-Resistance (Rds On): Lower values preferred for thermal performance
• Gate-Source Voltage (Vgs): Must accommodate ±20V maximum rating
• Power Dissipation: Must support thermal requirements of the application

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package Format: ATPAK, TO-252-3 (DPAK), or equivalent footprints
• Lead Configuration: 2 Leads + Tab standard

Compliance Requirements:

• RoHS3 Compliance mandatory
• Moisture Sensitivity Level (MSL): 1 (Unlimited) preferred

The three substitute parts listed below meet the core electrical specifications for P-Channel 40V MOSFET applications, though with variations in current rating and package format. Each substitute maintains the required voltage and thermal characteristics while offering different current handling capabilities and package options.

Engineering Selection Recommendations

IPD50P04P4L11ATMA1 (Infineon Technologies)

This substitute provides 50A continuous drain current with 40V Vdss rating in TO-252-3 DPAK package. The device is classified as "Not For New Designs," indicating limited future availability. On-resistance of 10.6 mOhm at 50A, 10V is comparable to the ATP108-TL-H. Power dissipation capability of 58W (Tc) is slightly lower than the original part. Operating temperature range extends to 175°C (TJ), exceeding the ATP108-TL-H specification of 150°C. Gate-source voltage maximum is ±16V, which is lower than the ±20V rating of the original device. This part is suitable for applications where 50A current capacity is sufficient and package conversion from ATPAK to TO-252-3 is acceptable.

NP50P04SDG-E1-AY (Renesas Electronics Corporation)

This substitute is classified as Active product status, ensuring long-term availability and supply continuity. It provides 50A continuous drain current with 40V Vdss in TO-252-3 DPAK package. On-resistance of 9.6 mOhm at 25A, 10V is superior to the ATP108-TL-H specification. Power dissipation capability of 84W (Tc) exceeds the original part, providing enhanced thermal performance. Operating temperature range extends to 175°C (TJ). Gate-source voltage rating of ±20V matches the ATP108-TL-H. Input capacitance of 5000 pF at 10V is higher than the original specification. This part is recommended for new designs and ongoing production where 50A current capacity meets application requirements.

TJ40S04M3L(T6L1,NQ (Toshiba Semiconductor and Storage)

This substitute provides 40A continuous drain current with 40V Vdss in DPAK+ package. The device is classified as Active, ensuring availability. On-resistance of 9.1 mOhm at 20A, 10V is superior to the ATP108-TL-H. Power dissipation capability of 68W (Tc) exceeds the original part. Operating temperature range extends to 175°C (TJ). Gate-source voltage rating is +10V, -20V, which differs from the ±20V symmetric rating of the ATP108-TL-H. This part is suitable for applications where 40A current capacity is sufficient and thermal performance is a priority.

Frequently Asked Questions (FAQ)

Q: Can the IPD50P04P4L11ATMA1 directly replace the ATP108-TL-H in existing designs?

A: The IPD50P04P4L11ATMA1 provides electrical compatibility at 40V, 50A operation with comparable on-resistance. However, the package differs from ATPAK to TO-252-3 DPAK, requiring PCB layout modification. The gate-source voltage maximum of ±16V is lower than the ATP108-TL-H specification of ±20V. Verification of gate drive voltage levels in the application circuit is necessary before substitution.

Q: What is the primary limitation of using the TJ40S04M3L(T6L1,NQ as a substitute?

A: The TJ40S04M3L(T6L1,NQ provides 40A continuous drain current, which is 30A lower than the ATP108-TL-H rating of 70A. This substitute is suitable only for applications where the maximum current requirement does not exceed 40A. The gate-source voltage rating of +10V, -20V differs from the symmetric ±20V specification of the original part.

Q: Why is the NP50P04SDG-E1-AY recommended for new designs?

A: The NP50P04SDG-E1-AY is classified as Active product status, ensuring long-term availability and supply chain continuity. It provides 50A continuous drain current with superior on-resistance of 9.6 mOhm and enhanced power dissipation capability of 84W (Tc). Gate-source voltage rating of ±20V matches the ATP108-TL-H specification. Operating temperature range of 175°C (TJ) exceeds the original part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three substitute parts listed are ROHS3 compliant, matching the compliance status of the ATP108-TL-H. All devices maintain Moisture Sensitivity Level (MSL) of 1 (Unlimited).

Q: What package conversion considerations apply when substituting from ATPAK to TO-252-3 DPAK?

A: ATPAK and TO-252-3 DPAK packages both feature 2 Leads + Tab configuration with identical electrical pin assignments. PCB footprint dimensions differ, requiring layout modification. Thermal performance may vary due to different package geometries and thermal resistance characteristics. Verification of thermal management in the application is recommended.

Q: Can multiple substitute parts be used interchangeably in the same application?

A: No. Each substitute part has distinct electrical characteristics including current rating, on-resistance, gate charge, and input capacitance. Selection must be based on specific application requirements for current capacity, thermal dissipation, and gate drive voltage compatibility. Mixing substitute parts in the same design is not recommended.

Q: What is the significance of the "Not For New Designs" status of the IPD50P04P4L11ATMA1?

A: This status indicates that Infineon Technologies is not recommending this part for new product development. While the part remains available in current inventory, future availability and supply continuity are not guaranteed. For new designs, the NP50P04SDG-E1-AY with Active status is preferred.
