ATP301-TL-H Equivalent & Substitute Parts

Part Overview

The ATP301-TL-H is a P-Channel MOSFET manufactured by onsemi, rated for 100V drain-to-source voltage with 28A continuous drain current in ATPAK surface mount packaging. This device is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within specified operating parameters while accommodating potential package and thermal characteristic differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATP301-TL-H is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: P-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Minimum 100V rating required
• Continuous Drain Current (Id): Minimum 26A at rated conditions
• Drive Voltage: 10V gate drive compatibility
• On-State Resistance (Rds On): Maximum 90 mOhm at specified conditions
• Gate Charge (Qg): Maximum 73 nC at 10V
• Maximum Gate-Source Voltage (Vgs): Minimum ±15V tolerance
• Input Capacitance (Ciss): Maximum 4000 pF at rated voltage
• Power Dissipation: Minimum 70W thermal capability
• Operating Temperature: Minimum 150°C junction temperature rating

Mechanical and Compliance Criteria:

• Surface Mount technology required
• RoHS3 compliance mandatory
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

The IXTY26P10T meets these substitution criteria with equivalent electrical performance and active product status, though package configuration differs from the original ATPAK form factor.

Parameter Comparison

Engineering Selection Recommendations

ATP301-TL-H Status: The ATP301-TL-H is classified as obsolete. Continued procurement from existing inventory is limited to 33,400 pieces. New designs should transition to active alternatives to ensure long-term supply chain stability and manufacturing support.

IXTY26P10T as Primary Substitute: The IXTY26P10T is an active product with 18,600 pieces in current inventory. This device maintains electrical equivalence across all critical parameters: 100V Vdss rating, 26A continuous drain current (within 93% of original specification), 10V drive voltage compatibility, and comparable on-state resistance characteristics. The IXTY26P10T features superior power dissipation capability (150W versus 70W), lower gate charge (52 nC versus 73 nC), and extended operating temperature range (-55°C to 150°C).

Compliance Status: Both devices maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity classification, ensuring regulatory continuity in production environments.

Package Consideration: The primary design constraint is package transition from ATPAK to TO-252-3 (DPAK) form factor. PCB layout modification is required to accommodate the different lead configuration and thermal tab positioning. Thermal performance improvement (150W versus 70W) may permit reduced heatsinking requirements in thermal-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the IXTY26P10T directly replace the ATP301-TL-H without circuit modification?

A: Electrical substitution is valid. The IXTY26P10T maintains 100V Vdss, 10V gate drive compatibility, and comparable on-state resistance. However, package geometry differs (TO-252-3 DPAK versus ATPAK), requiring PCB layout redesign. Pin-to-pin electrical connections are compatible with appropriate footprint adaptation.

Q: What is the current drain difference between these devices?

A: The ATP301-TL-H is rated for 28A continuous drain current (Ta), while the IXTY26P10T is rated for 26A (Tc). This represents a 7% reduction in current capacity. Applications operating near maximum current specifications require thermal analysis to confirm adequate margin with the substitute device.

Q: Does the IXTY26P10T provide better thermal performance?

A: Yes. The IXTY26P10T is rated for 150W power dissipation (Tc) compared to 70W (Tc) for the ATP301-TL-H. This 2.14× improvement in thermal capability results from the TO-252-3 package design and may reduce heatsinking requirements in thermally constrained applications.

Q: Are there compliance or regulatory differences between these devices?

A: No. Both devices are ROHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited). Regulatory and environmental compliance status is equivalent.

Q: What is the gate charge difference, and does it affect circuit performance?

A: The IXTY26P10T has lower gate charge (52 nC @ 10V) compared to the ATP301-TL-H (73 nC @ 10V), representing a 29% reduction. Lower gate charge reduces switching losses and gate drive power requirements, providing improved efficiency in high-frequency switching applications.

Q: Is the IXTY26P10T suitable for designs with ±20V gate drive capability?

A: The IXTY26P10T is rated for ±15V maximum gate-source voltage, compared to ±20V for the ATP301-TL-H. Designs utilizing ±20V gate drive must be modified to operate within ±15V limits. Standard gate drive circuits operating at ±10V or ±12V are fully compatible.

Q: What is the product availability status for long-term procurement?

A: The ATP301-TL-H is obsolete with limited inventory (33,400 pieces). The IXTY26P10T is an active product with current inventory (18,600 pieces) and ongoing manufacturing support, ensuring supply chain continuity for new designs and production ramp.
