FDD8876 N-Channel MOSFET 30V 15A/73A TO-252AA Equivalent & Substitute Parts

Part Overview

The FDD8876 is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with continuous drain current of 15A at Ta (ambient temperature) and 73A at Tc (case temperature). This device is packaged in the TO-252AA (DPAK) surface mount configuration and belongs to the PowerTrench® series. The FDD8876 is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, thermal characteristics, and package specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDD8876 are selected based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
• Continuous Drain Current (Id): Must support the application's current requirements
• On-State Resistance (Rds On): Lower values indicate improved performance; substitutes with comparable or lower Rds On are acceptable
• Gate Threshold Voltage (Vgs(th)): Must fall within compatible operating ranges
• Operating Temperature Range: Must span -55°C to 175°C minimum

Mechanical Compatibility Criteria:

• Package Type: Must be TO-252-3 (DPAK) surface mount configuration
• Mounting Type: Surface mount only
• Pin Configuration: 2 Leads + Tab standard

Regulatory Compliance:

• RoHS3 Compliance: Required
• REACH Status: Must be REACH Unaffected or compliant

The three substitute parts listed (IPD090N03LGATMA1, IPD30N03S4L09ATMA1, and IPD40N03S4L08ATMA1) all meet these core criteria. Differences in continuous drain current ratings and power dissipation reflect design variations within the acceptable substitution envelope.

Engineering Selection Recommendations

IPD30N03S4L09ATMA1 (Infineon Technologies)

This part is the primary recommended substitute for the FDD8876. It maintains full electrical compatibility with 30V Vdss and -55°C to 175°C operating temperature range. The continuous drain current of 30A (Tc) is lower than the FDD8876's 73A rating but remains suitable for applications within this current envelope. The part is currently in active production status with high inventory availability (48,787 pcs), ensuring long-term supply continuity. RoHS3 compliance and REACH unaffected status meet all regulatory requirements. The OptiMOS™ series technology provides optimized performance characteristics with lower gate charge (20 nC) compared to the FDD8876 (47 nC), resulting in improved switching efficiency.

IPD090N03LGATMA1 (Infineon Technologies)

This substitute offers higher continuous drain current capability at 40A (Tc), providing additional design margin for applications approaching the FDD8876's current limits. Electrical parameters remain compatible with 30V Vdss and full temperature range operation. The part is in active production status with 5,400 pcs in stock. Gate charge is significantly lower at 15 nC, offering superior switching performance. This part is suitable when higher current capacity is required within the same voltage and package constraints.

IPD40N03S4L08ATMA1 (Infineon Technologies)

This part provides 40A continuous drain current capability with the lowest on-state resistance (8.3 mOhm @ 40A, 10V) among the substitutes, matching the FDD8876's Rds On performance closely. However, this part is listed as discontinued at DiGi Electronics, limiting its availability for new designs. It is included for reference in legacy system support where existing inventory may be available. The part carries AEC-Q101 automotive qualification, indicating suitability for automotive applications if required.

Selection Priority:

For new designs and production continuity, IPD30N03S4L09ATMA1 is the recommended primary substitute due to active product status and high inventory availability. IPD090N03LGATMA1 serves as a secondary option when higher current capacity is required. IPD40N03S4L08ATMA1 should be considered only for legacy system support where supply has been secured.

Frequently Asked Questions (FAQ)

Q: Can the IPD30N03S4L09ATMA1 directly replace the FDD8876 in existing PCB layouts?

A: Yes. Both parts use identical TO-252-3 (DPAK) surface mount packaging with the same pin configuration (2 Leads + Tab). PCB footprints are directly compatible without modification.

Q: What is the significance of the lower continuous drain current rating in the IPD30N03S4L09ATMA1 (30A vs. 73A)?

A: The FDD8876 is rated for 73A at case temperature (Tc), while the IPD30N03S4L09ATMA1 is rated for 30A (Tc). The substitute is suitable for applications requiring up to 30A continuous current. Applications exceeding this threshold require either the IPD090N03LGATMA1 (40A) or thermal management design review to ensure case temperature remains within acceptable limits.

Q: Are there differences in gate drive requirements between the FDD8876 and substitute parts?

A: Gate threshold voltages are comparable (FDD8876: 2.5V max; substitutes: 2.2V max), ensuring compatible gate drive circuits. However, gate charge differs significantly (FDD8876: 47 nC; IPD30N03S4L09ATMA1: 20 nC; IPD090N03LGATMA1: 15 nC). Lower gate charge in substitutes results in faster switching transitions and reduced gate drive power consumption, which is beneficial for most applications.

Q: Do all substitute parts meet the same regulatory compliance as the FDD8876?

A: Yes. All three substitute parts are ROHS3 compliant and REACH unaffected, matching the FDD8876's regulatory status. IPD40N03S4L08ATMA1 additionally carries AEC-Q101 automotive qualification.

Q: What is the impact of lower power dissipation ratings in the substitutes (42W vs. 70W)?

A: The FDD8876 is rated for 70W power dissipation at case temperature, while substitutes are rated for 42W. This reflects differences in die design and thermal characteristics. For applications operating below 42W, substitutes are fully compatible. Applications approaching or exceeding 42W require thermal analysis to confirm case temperature remains within the -55°C to 175°C operating range.

Q: Why is IPD40N03S4L08ATMA1 listed as discontinued?

A: IPD40N03S4L08ATMA1 is discontinued at DiGi Electronics, a major distributor, but may remain available through other channels or existing inventory. This part is included for reference in legacy system support scenarios. For new designs, IPD30N03S4L09ATMA1 or IPD090N03LGATMA1 are recommended.

Q: Are there thermal management considerations when substituting the FDD8876?

A: Yes. The FDD8876's higher power dissipation rating (70W) indicates it was designed for higher thermal loads. When substituting with lower-rated parts, verify that actual power dissipation in the application remains below the substitute's rating. If thermal margins are tight, consider IPD090N03LGATMA1 (40A) for additional current capacity, which may reduce on-state losses in current-limited applications.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Gate charge differences affect switching speed. Substitutes with lower gate charge (IPD090N03LGATMA1: 15 nC; IPD30N03S4L09ATMA1: 20 nC) enable faster switching compared to the FDD8876 (47 nC). This is generally advantageous, reducing switching losses and improving efficiency. Gate drive circuits must supply sufficient current to charge/discharge the gate within the required switching time.

Q: What packaging options are available for these substitutes?

A: All substitute parts are supplied in TO-252-3 (DPAK) surface mount configuration only. IPD30N03S4L09ATMA1 and IPD090N03LGATMA1 are available in Tape & Reel (TR) packaging for automated assembly. No alternative package options are provided for these substitutes.
