IRF830PBF N-Channel MOSFET 500V 4.5A Equivalent & Substitute Parts

Part Overview

The IRF830PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 500V drain-to-source voltage with 4.5A continuous drain current at 25°C. This device is packaged in TO-220AB through-hole configuration and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts from active manufacturers is essential for design continuity and procurement planning. The IRF830PBF operates across a temperature range of -55°C to 150°C (junction temperature) and dissipates up to 74W at the case temperature.

All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the original IRF830PBF, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: IRF830PBF-BE3 (Vishay Siliconix)

The IRF830PBF-BE3 is the direct manufacturer equivalent from Vishay Siliconix. This part maintains active product status, ensuring long-term availability and supply chain stability. All electrical parameters, mechanical specifications, and compliance certifications are identical to the original Infineon IRF830PBF. The IRF830PBF-BE3 is supplied in tube packaging and carries ROHS3 compliance with MSL Level 1 rating.

Secondary Recommendation: IRF830PBF (Vishay Siliconix)

The Vishay Siliconix IRF830PBF is a parametric equivalent offering identical electrical and mechanical characteristics. This part is also in active production status. The primary distinction is REACH status classification (REACH Affected versus REACH Unaffected for the original Infineon part). Both Vishay options provide equivalent functional performance and are suitable for direct substitution in applications previously using the Infineon IRF830PBF.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and EAR99 export classification. The Vishay IRF830PBF carries REACH Affected status, while the IRF830PBF-BE3 status is vendor-undefined. Organizations with specific REACH compliance requirements should verify regulatory status with the supplier before final selection.

Frequently Asked Questions (FAQ)

Q: Can the IRF830PBF-BE3 directly replace the obsolete Infineon IRF830PBF?

A: Yes. The IRF830PBF-BE3 is a direct equivalent with identical electrical specifications, on-state resistance, gate charge, input capacitance, and power dissipation ratings. The TO-220-3 package and through-hole mounting are mechanically compatible with existing PCB designs.

Q: What is the difference between IRF830PBF-BE3 and IRF830PBF from Vishay?

A: Both parts are from Vishay Siliconix and share identical electrical and mechanical parameters. The primary difference is packaging format: IRF830PBF-BE3 is supplied in tube packaging, while the IRF830PBF packaging format is specified as tube. REACH status differs between the two variants. Consult the supplier datasheet for specific packaging and compliance details.

Q: Are there any thermal or electrical performance differences between the Infineon and Vishay versions?

A: No. All thermal characteristics, including maximum power dissipation (74W at case temperature) and operating temperature range (-55°C to 150°C junction temperature), are identical across all three part numbers. On-state resistance (1.5 Ohm @ 2.7A, 10V) and gate charge (38 nC @ 10V) specifications are matched.

Q: Is the TO-220-3 package compatible with existing PCB layouts?

A: Yes. All substitute parts use the TO-220-3 through-hole package, which is mechanically and electrically compatible with PCB designs originally specified for the Infineon IRF830PBF. No PCB redesign is required.

Q: What is the inventory status for substitute parts?

A: The Infineon IRF830PBF (obsolete) has 25,300 pieces in stock. The Vishay IRF830PBF-BE3 has 4,109 pieces available. The Vishay IRF830PBF has 25,300 pieces in stock. Availability should be confirmed with the supplier for production requirements.

Q: Do the substitute parts meet RoHS and export compliance requirements?

A: Yes. All parts are ROHS3 compliant and classified as EAR99 for export purposes. HTSUS code 8541.29.0095 applies to all variants. REACH status varies: verify specific regulatory requirements with your compliance team before final selection.

Q: Can these parts be used in high-temperature applications?

A: Yes. All parts operate across the full temperature range of -55°C to 150°C (junction temperature), supporting both industrial and high-temperature circuit applications within this specification window.
