FDG330P Equivalent & Substitute Parts

Part Overview

The FDG330P is a P-Channel MOSFET manufactured by onsemi, rated for 12V drain-to-source voltage with 2A continuous drain current at 25°C. The device is housed in a 6-pin SC-88 (SC-70-6) surface mount package and dissipates up to 750mW. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement.

Substitute parts must maintain compatibility with the original circuit topology while meeting or exceeding the electrical performance requirements of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDG330P is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain-to-Source Voltage (Vdss) must equal or exceed 12V
• Continuous Drain Current (Id) must equal or exceed 2A at 25°C
• On-State Resistance (Rds On) should not significantly exceed 110 mOhm to maintain thermal performance
• Gate Threshold Voltage (Vgs(th)) must be compatible with existing gate drive circuitry
• Maximum Gate Voltage (Vgs Max) must be ±8V or greater
• Operating temperature range must encompass -55°C to 150°C

Physical Compatibility Requirements:

• Package type must be SC-88 (SC-70-6) or equivalent 6-pin surface mount configuration
• Mounting type must be surface mount
• Pin configuration must be compatible with existing PCB layouts

Regulatory and Compliance Requirements:

• Moisture Sensitivity Level (MSL) must be 1 (Unlimited) or equivalent
• REACH and ECCN compliance status must be maintained

The substitute parts identified below meet these criteria with enhanced or equivalent electrical performance characteristics.

Engineering Selection Recommendations

FDG332PZ (onsemi) - Direct Substitute

The FDG332PZ is the primary substitute for the FDG330P. Both devices are manufactured by onsemi within the PowerTrench® series and share identical package configurations (SC-88, SC-70-6). The FDG332PZ offers enhanced electrical performance with a higher Vdss rating (20V versus 12V), increased continuous drain current (2.6A versus 2A), and improved on-state resistance (95 mOhm versus 110 mOhm). The FDG332PZ maintains active product status, ensuring long-term availability and supply chain stability. All regulatory compliance parameters (REACH, ECCN, MSL) are equivalent. The higher voltage rating provides additional design margin for transient protection without compromising thermal performance, as both devices dissipate 750mW maximum.

AO7411 (Alpha & Omega Semiconductor Inc.) - Alternative Substitute

The AO7411 provides an alternative substitute option from a different manufacturer. This device meets the minimum electrical requirements with a 20V Vdss rating and maintains the required operating temperature range. The AO7411 features a lower gate charge (6.24 nC versus 7 nC), which may reduce gate drive power consumption. However, the continuous drain current rating (1.8A) is below the original FDG330P specification (2A), and the on-state resistance (120 mOhm) is higher than both the original part and the FDG332PZ. The AO7411 is suitable for applications where the 1.8A current rating is sufficient and where lower gate charge is beneficial. The device maintains active product status and equivalent compliance certifications. The SC-70-6 package is compatible with SC-88 footprints in most applications.

Selection Criteria:

• Use FDG332PZ for direct replacement requiring maximum performance margin and onsemi product continuity
• Use AO7411 when lower gate charge is advantageous and application current requirements do not exceed 1.8A
• Both substitutes are active products with established supply chains, addressing the obsolescence of the FDG330P

Frequently Asked Questions (FAQ)

Q: Can the FDG332PZ be used as a direct drop-in replacement for the FDG330P?

A: Yes. The FDG332PZ is electrically and mechanically compatible with the FDG330P. Both devices use the SC-88 (SC-70-6) package with identical pin configurations. The FDG332PZ provides enhanced performance with higher voltage rating (20V versus 12V) and improved on-state resistance (95 mOhm versus 110 mOhm), making it suitable for direct substitution without circuit modification.

Q: What is the primary advantage of the FDG332PZ over the FDG330P?

A: The FDG332PZ offers a higher drain-to-source voltage rating (20V versus 12V), increased continuous drain current capability (2.6A versus 2A), and lower on-state resistance (95 mOhm versus 110 mOhm). Additionally, the FDG332PZ maintains active product status, ensuring long-term availability compared to the obsolete FDG330P.

Q: Is the AO7411 suitable for all applications using the FDG330P?

A: The AO7411 is suitable for applications where the continuous drain current requirement does not exceed 1.8A. The device has a higher on-state resistance (120 mOhm) compared to the FDG330P (110 mOhm), which may result in increased power dissipation in high-current applications. The AO7411 is recommended for applications prioritizing lower gate charge and where current requirements are within its 1.8A rating.

Q: Are there package compatibility concerns when substituting these parts?

A: All three devices use compatible 6-pin surface mount packages (SC-88 or SC-70-6). The pin configurations are identical, and PCB footprints are interchangeable. No layout modifications are required for substitution.

Q: What is the impact of the higher gate charge in the FDG332PZ compared to the AO7411?

A: The FDG332PZ has a gate charge of 10.8 nC at 4.5V, while the AO7411 has 6.24 nC. Higher gate charge requires more energy from the gate drive circuit to switch the device. In applications with limited gate drive capability, the AO7411 may be preferable. In most standard applications, the difference is negligible.

Q: Do all substitute parts meet the same regulatory and compliance requirements?

A: Yes. Both the FDG332PZ and AO7411 maintain REACH Unaffected status, EAR99 ECCN classification, and MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the FDG330P.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across the same temperature range as the FDG330P: -55°C to 150°C (TJ). No thermal performance limitations exist when substituting these devices.

Q: Why is the FDG330P classified as obsolete?

A: The FDG330P is an older generation PowerTrench® MOSFET. onsemi has superseded this device with the FDG332PZ, which offers improved electrical performance and maintains active production status. The obsolescence classification indicates that the original part is no longer in active production, making substitution necessary for new designs and ongoing procurement.
