FDB6030L Equivalent & Substitute Parts

Part Overview

The FDB6030L is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 48A continuous drain current in a surface mount TO-263 (D2PAK) package. This device is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement requirements. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDB6030L are qualified based on the following electrical and mechanical criteria:

Mandatory Compatibility Parameters:

• Drain to Source Voltage (Vdss): 30 V (exact match required)
• Package Type: TO-263-3, D2PAK (2 Leads + Tab) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Technology: N-Channel MOSFET (exact match required)

Performance Parameters (allowable variation):

• Continuous Drain Current (Id): Substitute must meet or exceed 48 A requirement
• Rds On (Max): Lower values are acceptable (improved performance)
• Gate Charge (Qg): Variation permitted within design margin
• Power Dissipation (Max): Substitute must support thermal requirements
• Operating Temperature Range: Substitute must cover or exceed -65°C ~ 175°C range

The following parts satisfy these substitution criteria:

1. PSMN017-30BL,118 (Nexperia USA Inc.) – Lower current rating (32 A), suitable for applications not requiring full 48 A capacity
2. PSMN4R3-30BL,118 (Nexperia USA Inc.) – Higher current rating (100 A), suitable for applications requiring enhanced current handling

Parameter Comparison

Engineering Selection Recommendations

PSMN017-30BL,118 Selection Criteria:

• Suitable for applications where continuous drain current requirement is 32 A or less
• Product status is obsolete; use only when existing inventory is available
• ROHS3 compliant; meets modern environmental standards
• Operating temperature range (-55°C ~ 175°C) covers most industrial applications but does not extend to -65°C minimum of original part
• Lower gate charge (10.7 nC) reduces switching losses compared to FDB6030L

PSMN4R3-30BL,118 Selection Criteria:

• Suitable for applications requiring continuous drain current up to 100 A
• Product status is active; recommended for new designs requiring long-term availability
• ROHS3 compliant; meets modern environmental standards
• Operating temperature range (-55°C ~ 175°C) covers most industrial applications but does not extend to -65°C minimum of original part
• Superior on-resistance (4.1 mOhm) provides lower power dissipation in high-current applications
• Higher gate charge (41.5 nC) increases switching losses but supports higher current handling

Frequently Asked Questions (FAQ)

Q: Can PSMN017-30BL,118 directly replace FDB6030L in all applications?

A: No. PSMN017-30BL,118 has a maximum continuous drain current of 32 A, compared to FDB6030L's 48 A. Direct substitution is only valid for applications where the actual operating current does not exceed 32 A. Verify circuit current requirements before selection.

Q: What is the primary advantage of PSMN4R3-30BL,118 over FDB6030L?

A: PSMN4R3-30BL,118 offers significantly lower on-resistance (4.1 mOhm versus 13 mOhm) and higher continuous drain current rating (100 A versus 48 A). These characteristics reduce power dissipation and thermal stress in high-current switching applications. Additionally, PSMN4R3-30BL,118 has active product status, ensuring long-term availability.

Q: Are all three parts pin-compatible?

A: Yes. FDB6030L, PSMN017-30BL,118, and PSMN4R3-30BL,118 all use the TO-263-3 (D2PAK) package with identical pin configuration (2 leads plus tab). PCB layout modifications are not required for package compatibility.

Q: What is the impact of the operating temperature range difference?

A: FDB6030L specifies -65°C ~ 175°C, while both Nexperia substitutes specify -55°C ~ 175°C. If the application requires operation below -55°C, neither substitute is suitable. For applications within -55°C ~ 175°C range, both substitutes are compatible.

Q: Which substitute should be selected for new product designs?

A: PSMN4R3-30BL,118 is recommended for new designs due to active product status, ensuring availability throughout the product lifecycle. PSMN017-30BL,118 should only be considered if current requirements are confirmed below 32 A and existing inventory is available.

Q: Are there compliance differences between the parts?

A: FDB6030L status is REACH Unaffected. Both PSMN017-30BL,118 and PSMN4R3-30BL,118 are ROHS3 compliant and REACH Unaffected. All three parts carry ECCN EAR99 classification and HTSUS 8541.29.0095 tariff code.

Q: How do gate charge differences affect circuit performance?

A: FDB6030L has 18 nC gate charge at 5 V. PSMN017-30BL,118 has lower gate charge (10.7 nC at 10 V), reducing driver power requirements and switching losses. PSMN4R3-30BL,118 has higher gate charge (41.5 nC at 10 V), requiring stronger gate drive but supporting higher current levels. Gate driver capability must be verified for each substitute.
