This part carries automotive-grade qualification (AEC-Q101) and is suitable only for applications where maximum operating voltage does not exceed 60V. Power dissipation rating is 375W, exceeding the primary part. Product status is Active with 4314 units in inventory.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and -55°C to 175°C operating temperature range. AUIRFS3107TRL and SQM120N06-3M5L_GE3 carry AEC-Q101 automotive qualification. Selection should prioritize Active status parts (PSMN2R8-80BS,118, PSMN3R3-80BS,118, STB160N75F3, SQM120N06-3M5L_GE3) over Last Time Buy status (AUIRFS3107TRL) for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q1: Can AUIRFS3107TRL be used as a direct replacement for IRFS3107TRLPBF?

A: Yes. AUIRFS3107TRL is a parametric equivalent with identical electrical specifications: 75V Vdss, 195A continuous drain current, 3mOhm Rds On at 140A/10V, and D2PAK packaging. Both parts are manufactured by Infineon Technologies and maintain identical gate charge (240nC), input capacitance (9370pF), and operating temperature range (-55°C to 175°C). The primary difference is product status: IRFS3107TRLPBF is Active, while AUIRFS3107TRL is Last Time Buy. AUIRFS3107TRL includes automotive-grade qualification (AEC-Q101), which may be advantageous for automotive applications.

Q2: What are the limitations when substituting with PSMN2R8-80BS,118 or PSMN3R3-80BS,118?

A: Both Nexperia parts are rated for 120A continuous drain current, which is 61.5% of the primary part's 195A rating. These substitutes are suitable only for applications where maximum continuous current does not exceed 120A. Voltage rating is 80V, exceeding the primary 75V specification, providing margin for overvoltage conditions. Both parts maintain D2PAK packaging and ±20V gate-source voltage rating. Rds On specifications differ: PSMN2R8-80BS,118 provides 3mOhm at 25A/10V; PSMN3R3-80BS,118 provides 3.5mOhm at 25A/10V. Gate charge is significantly lower (139nC and 111nC respectively) compared to the primary part (240nC).

Q3: Is STB160N75F3 a suitable substitute for high-current applications?

A: STB160N75F3 is limited to 120A continuous drain current, making it unsuitable for applications requiring the primary part's 195A rating. This STMicroelectronics part maintains the 75V voltage rating and D2PAK packaging. Rds On is specified at 4mOhm (60A, 10V), higher than the primary part's 3mOhm specification. Gate charge is 85nC, significantly lower than the primary part's 240nC, which may reduce gate drive requirements. STB160N75F3 is appropriate for designs where current requirements do not exceed 120A and lower gate charge is beneficial.

Q4: When should SQM120N06-3M5L_GE3 be considered?

A: SQM120N06-3M5L_GE3 should be considered only when application maximum drain-to-source voltage does not exceed 60V. This Vishay Siliconix part operates at 20% lower voltage rating than the primary part. The device is rated for 120A continuous current and includes automotive-grade qualification (AEC-Q101). Power dissipation rating is 375W, exceeding the primary part. This substitute is appropriate for automotive applications operating at reduced voltage levels where AEC-Q101 qualification is required.

Q5: Are all substitute parts compatible with the same PCB layout and thermal management design?

A: All substitute parts use D2PAK (TO-263-3) surface mount packaging, ensuring mechanical and thermal interface compatibility with the primary part's PCB footprint. However, thermal performance differs due to varying power dissipation ratings and current capabilities. IRFS3107TRLPBF and AUIRFS3107TRL are rated for 370W; PSMN2R8-80BS,118 and PSMN3R3-80BS,118 are rated for 306W; STB160N75F3 is rated for 330W; SQM120N06-3M5L_GE3 is rated for 375W. Thermal design calculations should account for actual operating current and Rds On specifications of the selected substitute to ensure adequate heat dissipation.

Q6: What is the significance of product status (Active vs. Last Time Buy)?

A: Product status indicates the manufacturing and supply phase. Active status means the part is in full production with established supply chains and long-term availability. Last Time Buy status indicates the manufacturer is discontinuing production; customers must place final orders within a specified window. IRFS3107TRLPBF is Active with 6677 units in inventory, ensuring continued availability. AUIRFS3107TRL is Last Time Buy, requiring confirmation of remaining supply before selection for new designs. For applications requiring long-term component availability, Active status parts (PSMN2R8-80BS,118, PSMN3R3-80BS,118, STB160N75F3, SQM120N06-3M5L_GE3) are preferred.

Q7: How do gate charge differences affect circuit design?

A: Gate charge (Qg) determines the energy required to switch the MOSFET on and off. IRFS3107TRLPBF and AUIRFS3107TRL specify 240nC gate charge at 10V. Substitute parts have lower gate charge: PSMN2R8-80BS,118 (139nC), PSMN3R3-80BS,118 (111nC), STB160N75F3 (85nC), and SQM120N06-3M5L_GE3 (330nC). Lower gate charge reduces gate drive power requirements and may enable faster switching transitions. Higher gate charge (SQM120N06-3M5L_GE3) requires increased gate drive capability. Gate drive circuit design should be verified for compatibility with the selected substitute's gate charge specification.

Q8: What compliance certifications are provided with each part?

A: All parts are ROHS3 compliant and have Unlimited moisture sensitivity level (MSL 1). IRFS3107TRLPBF, PSMN2R8-80BS,118, PSMN3R3-80BS,118, and STB160N75F3 do not carry automotive-grade qualification. AUIRFS3107TRL and SQM120N06-3M5L_GE3 carry AEC-Q101 automotive qualification. All parts are REACH Unaffected or REACH compliant. ECCN classification is EAR99 for all parts. Selection should prioritize AEC-Q101 qualification when automotive applications require formal qualification documentation.
