FDP6035AL Equivalent & Substitute Parts

Part Overview

The FDP6035AL is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 48A continuous drain current in a Through Hole TO-220-3 package. This device is classified as Obsolete product status. Locating equivalent and substitute parts is necessary due to discontinued production and potential supply constraints. Substitute parts must maintain compatibility across voltage ratings, current handling capability, package form factor, and thermal characteristics to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDP6035AL is based on the following critical parameters that must be maintained or exceeded:

Voltage Rating: Drain-to-source voltage (Vdss) must be 30V or greater to ensure safe operation within the same circuit topology.

Current Capability: Continuous drain current (Id) must support the application's maximum current demand. The FDP6035AL provides 48A; substitute parts with lower current ratings require circuit re-evaluation.

Package Compatibility: The TO-220-3 Through Hole package is the primary mechanical constraint. Substitute parts must use compatible package types to maintain PCB layout and thermal management integrity.

On-State Resistance (Rds On): This parameter directly affects power dissipation and thermal performance. Lower Rds On values improve efficiency; higher values increase heat generation.

Operating Temperature Range: The device must operate across the application's required temperature extremes. The FDP6035AL supports -65°C to 175°C.

Gate Charge and Input Capacitance: These parameters influence switching speed and gate drive requirements. Significant deviations may require gate driver circuit modifications.

The PSMN022-30PL,127 from Nexperia USA Inc. is identified as a substitute part. This device shares the same 30V voltage rating and TO-220 package family, but provides 30A continuous drain current, which is lower than the FDP6035AL's 48A rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Current Rating Mismatch: The PSMN022-30PL,127 provides 30A continuous drain current compared to the FDP6035AL's 48A. This 37.5% reduction in current capacity represents a significant functional difference. Selection of this substitute is appropriate only for applications where the maximum required drain current does not exceed 30A.

Voltage Rating Equivalence: Both devices maintain the same 30V Vdss rating, ensuring compatibility with circuits designed for this voltage class.

Package Compatibility: The FDP6035AL uses TO-220-3 packaging while the PSMN022-30PL,127 uses TO-220AB packaging. Both are Through Hole TO-220 family variants with compatible pin configurations and thermal characteristics for standard PCB layouts.

Thermal Performance: The PSMN022-30PL,127 has lower maximum power dissipation (41W vs. 52W), consistent with its reduced current rating. Thermal management requirements may be less stringent with this substitute.

Temperature Range: The PSMN022-30PL,127 operates from -55°C to 175°C, compared to the FDP6035AL's -65°C to 175°C. Applications requiring operation below -55°C cannot use this substitute.

Compliance Status: The PSMN022-30PL,127 carries ROHS3 compliance certification. Both devices are REACH Unaffected and classified under ECCN EAR99.

Product Status: Both devices are classified as Obsolete. Long-term availability of either part cannot be assured.

Frequently Asked Questions (FAQ)

Q: Can the PSMN022-30PL,127 directly replace the FDP6035AL in all applications?

A: Direct replacement is limited by current rating. The PSMN022-30PL,127 provides 30A continuous drain current versus the FDP6035AL's 48A. Substitution is valid only when application current requirements do not exceed 30A. For applications requiring 30A to 48A, this substitute is not functionally equivalent.

Q: What is the significance of the different package designations (TO-220-3 vs. TO-220AB)?

A: Both designations refer to Through Hole TO-220 family packages with compatible pin configurations and mounting footprints. TO-220-3 and TO-220AB are mechanically and electrically interchangeable for standard PCB applications. The primary difference is manufacturer nomenclature; both support identical thermal management approaches.

Q: How does the on-state resistance difference affect circuit performance?

A: The PSMN022-30PL,127 exhibits 22 mOhm Rds On (measured at 5A, 10V) compared to the FDP6035AL's 12 mOhm (measured at 24A, 10V). Higher on-state resistance increases power dissipation and heat generation. At equivalent current levels, the PSMN022-30PL,127 will dissipate approximately 83% more power due to the resistance differential. Circuit thermal design must account for this increased dissipation.

Q: Are there temperature range limitations with the PSMN022-30PL,127?

A: The PSMN022-30PL,127 operates from -55°C to 175°C, while the FDP6035AL operates from -65°C to 175°C. Applications requiring operation below -55°C cannot use the PSMN022-30PL,127 as a substitute.

Q: What do the gate charge and input capacitance differences mean for gate driver design?

A: The PSMN022-30PL,127 has lower gate charge (9 nC at 10V vs. 18 nC at 5V) and significantly lower input capacitance (447 pF vs. 1250 pF). These lower values typically result in faster switching transitions and reduced gate driver current requirements. Existing gate driver circuits designed for the FDP6035AL will function with the PSMN022-30PL,127, though switching performance will improve.

Q: What is the impact of both devices being classified as Obsolete?

A: Obsolete product status indicates discontinued manufacturing. Both the FDP6035AL and PSMN022-30PL,127 are no longer in active production. Inventory availability is limited to existing stock. For new designs, evaluation of current-generation N-Channel 30V MOSFETs from active product lines is recommended to ensure long-term supply chain viability.

Q: How do the different measurement conditions for Rds On affect comparison?

A: The FDP6035AL specifies Rds On at 24A and 10V gate voltage, while the PSMN022-30PL,127 specifies it at 5A and 10V gate voltage. On-state resistance varies with both drain current and gate voltage. Direct numerical comparison at different measurement points does not provide equivalent performance data. The PSMN022-30PL,127's lower current measurement point (5A vs. 24A) typically yields lower resistance values than would be observed at higher currents, making direct comparison imprecise.
