AOB2906 N-Channel MOSFET 100V 122A TO-263 Equivalent & Substitute Parts

Part Overview

The AOB2906 is an N-Channel MOSFET manufactured by Alpha & Omega Semiconductor Inc., rated for 100V drain-to-source voltage with 122A continuous drain current at 25°C in a Surface Mount TO-263 (D2PAK) package. This device is part of the AlphaSGT™ series and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent substitute parts are necessary to maintain design continuity and ensure long-term supply chain reliability for applications requiring comparable electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AOB2906 are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

1. Drain to Source Voltage (Vdss): Must equal or exceed 100V to maintain voltage rating compatibility
2. Continuous Drain Current (Id): Must meet or exceed 122A at 25°C to support the same current-handling capacity
3. Package Type: Must be TO-263-3, D2PAK (2 Leads + Tab), or TO-263AB to ensure mechanical and thermal interface compatibility
4. Mounting Type: Must be Surface Mount to maintain PCB assembly compatibility
5. FET Type & Technology: Must be N-Channel MOSFET to preserve circuit functionality

Substitute parts are grouped into two categories based on their electrical performance relative to the AOB2906:

Category A - Direct Current Equivalents (≥122A @ 100V): Parts meeting or exceeding both the voltage and current ratings of the AOB2906, providing direct functional replacement without derating.

Category B - Reduced Current Alternatives (75A–131A @ 100V): Parts with 100V rating but lower continuous drain current ratings, suitable for applications where the full 122A capacity is not required or where thermal management allows operation within the substitute's current limits.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement Capability)

IXFA180N10T2 (IXYS) and IXTA180N10T (IXYS) are the preferred substitutes for the AOB2906. Both devices are rated for 100V / 180A, exceeding the AOB2906's 122A specification and providing enhanced current-handling capacity. Both are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental compliance. The IXFA180N10T2 is packaged in Tube format, while IXTA180N10T is also in Tube format. Both maintain identical TO-263-3 D2PAK mechanical compatibility.

SUM70060E-GE3 (Vishay Siliconix) is a secondary substitute rated for 100V / 131A, providing current capacity exceeding the AOB2906's 122A requirement. This device is an active product with ROHS3 compliance, MSL 1 rating, and is part of the ThunderFET® series. It maintains full TO-263-3 D2PAK package compatibility.

Alternative Substitute (Reduced Voltage Rating)

IPB067N08N3GATMA1 (Infineon Technologies) is rated for 80V / 80A and represents a reduced-specification alternative. This device is suitable only for applications where the 100V voltage rating is not required and where the 80A current capacity is sufficient. This part is an active product with ROHS3 compliance and is qualified to AEC-Q101 automotive standards.

Not Recommended

SQM70060EL_GE3 (Vishay Siliconix) is rated for 100V / 75A, which falls below the AOB2906's 122A continuous drain current specification. This part is suitable only for applications where current requirements do not exceed 75A.

All substitute parts maintain Surface Mount TO-263-3 D2PAK package compatibility, MSL 1 moisture sensitivity, and operating temperature range of -55°C to 175°C (TJ).

Frequently Asked Questions (FAQ)

Q: Can the IPB067N08N3GATMA1 be used as a direct replacement for the AOB2906?

A: No. The IPB067N08N3GATMA1 is rated for 80V maximum drain-to-source voltage, which is below the AOB2906's 100V rating. Use of this part in a 100V application would result in device failure. Additionally, its 80A continuous drain current rating is below the AOB2906's 122A specification. This part is suitable only for applications with lower voltage and current requirements.

Q: What is the difference between IXFA180N10T2 and IXTA180N10T?

A: Both devices are rated identically at 100V / 180A and use the same TO-263-3 D2PAK package. The primary difference is packaging format: IXFA180N10T2 is supplied in Tube format, while IXTA180N10T is also supplied in Tube format. Both are active products with equivalent electrical performance and compliance certifications. Selection between these two parts is based on packaging and inventory availability requirements.

Q: Is the SQM70060EL_GE3 suitable for the AOB2906 application?

A: The SQM70060EL_GE3 is rated for 100V / 75A, which is below the AOB2906's 122A continuous drain current specification. This part is not suitable for applications requiring the full 122A capacity. However, it may be used in applications where continuous drain current does not exceed 75A. The SQM70060EL_GE3 maintains full TO-263-3 D2PAK package compatibility and is AEC-Q101 qualified for automotive applications.

Q: Are all substitute parts compatible with the same PCB footprint as the AOB2906?

A: Yes. All substitute parts listed use the TO-263-3 D2PAK (2 Leads + Tab) package, which maintains identical mechanical and thermal interface compatibility with the AOB2906. No PCB layout modifications are required for substitution.

Q: What is the significance of the MSL 1 rating on these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All listed substitute parts carry MSL 1 rating, matching the AOB2906's moisture sensitivity specification. This ensures equivalent handling and storage requirements.

Q: Why is the AOB2906 classified as obsolete?

A: The AOB2906 is no longer in active production by Alpha & Omega Semiconductor Inc. Obsolete status indicates that the manufacturer has discontinued this product line. Active substitute parts from manufacturers such as IXYS, Infineon Technologies, and Vishay Siliconix provide equivalent or superior electrical performance with guaranteed long-term availability and supply chain support.

Q: Can SUM70060E-GE3 be used in all applications where AOB2906 was previously used?

A: Yes. The SUM70060E-GE3 is rated for 100V / 131A, which exceeds the AOB2906's 100V / 122A specification. It maintains identical TO-263-3 D2PAK package compatibility and operating temperature range (-55°C to 175°C). The SUM70060E-GE3 is an active product with ROHS3 compliance and is suitable for direct substitution in all AOB2906 applications.

Q: What compliance certifications should I verify when selecting a substitute?

A: All listed substitute parts carry ROHS3 compliance and MSL 1 moisture sensitivity rating, matching the AOB2906's environmental compliance profile. The SQM70060EL_GE3 additionally carries AEC-Q101 automotive qualification. Verify that the selected substitute meets any application-specific compliance requirements, such as automotive, industrial, or medical certifications.
