Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF830S is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical for Functional Compatibility):

• Drain-to-Source Voltage (Vdss): 500V
• Continuous Drain Current (Id): 4.5A @ 25°C
• On-State Resistance (Rds On): 1.5 Ohm @ 2.7A, 10V
• Gate Threshold Voltage (Vgs(th)): 4V @ 250µA
• Gate Charge (Qg): 38 nC @ 10V
• Power Dissipation: 3.1W (Ta), 74W (Tc)
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Critical for Physical Compatibility):

• Mounting Type: Surface Mount
• Package: TO-263 (D2PAK)
• Pin Configuration: 2 Leads + Tab

The IRF830SPBF meets all electrical and mechanical requirements for direct substitution. The primary distinction is product status and compliance certification, with IRF830SPBF carrying Active status and RoHS3 compliance, compared to the Obsolete status of IRF830S.

Parameter Comparison

Engineering Selection Recommendations

IRF830SPBF is the direct substitute for IRF830S based on complete electrical and mechanical parameter equivalence. Selection of IRF830SPBF provides the following advantages:

Product Status: IRF830SPBF carries Active product status, ensuring ongoing manufacturing availability and supply chain continuity. IRF830S is Obsolete, limiting future procurement options.

Compliance Certification: IRF830SPBF is RoHS3 Compliant, meeting current environmental and regulatory requirements for electronic components in regulated markets. IRF830S is RoHS non-compliant, which may restrict use in applications subject to RoHS directives.

Electrical Performance: All electrical parameters are identical between IRF830S and IRF830SPBF, including Vdss, Id, Rds On, Vgs(th), gate charge, and power dissipation ratings. No circuit redesign or thermal management modifications are required.

Mechanical Compatibility: Both devices use identical Surface Mount TO-263 (D2PAK) packaging with 2 leads plus tab configuration. PCB layout and thermal interface requirements remain unchanged.

Packaging: IRF830SPBF is supplied in Tube packaging, suitable for automated assembly processes and component handling.

Frequently Asked Questions (FAQ)

Q: Can IRF830SPBF be used as a direct replacement for IRF830S in existing designs?

A: Yes. IRF830SPBF is electrically and mechanically identical to IRF830S. All electrical parameters, including Vdss (500V), Id (4.5A), Rds On (1.5 Ohm), and operating temperature range (-55°C to 150°C), are equivalent. The TO-263 (D2PAK) package footprint and pin configuration are identical, requiring no PCB modifications.

Q: What is the primary difference between IRF830S and IRF830SPBF?

A: The primary differences are product status and compliance certification. IRF830SPBF is Active and RoHS3 Compliant, while IRF830S is Obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Why is IRF830S listed as Obsolete?
