IRF830AS N-Channel MOSFET 500V 5A Equivalent & Substitute Parts

Part Overview

The IRF830AS is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 500V drain-to-source voltage with 5A continuous drain current. The device is housed in a TO-263 (D2PAK) surface mount package and is designed for high-voltage switching applications. The IRF830AS is classified as obsolete, making identification of functionally equivalent active alternatives necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF830AS is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Drain-to-source voltage rating (Vdss): 500V
• Continuous drain current (Id): 5A at 25°C
• On-state resistance (Rds On): 1.4Ω maximum at specified conditions
• Gate threshold voltage (Vgs(th)): 4.5V maximum
• Gate charge (Qg): 24nC maximum
• Maximum gate-source voltage (Vgs): ±30V
• Input capacitance (Ciss): 620pF maximum
• Power dissipation capability: 3.1W (Ta), 74W (Tc)
• Operating temperature range: -55°C to 150°C

Mechanical Parameters:

• Mounting type: Surface Mount
• Package designation: TO-263 (D2PAK)
• Pin configuration: 2 Leads + Tab

Substitute parts must match all electrical specifications and maintain identical package geometry and pin configuration to ensure direct board-level compatibility without layout modification.

Parameter Comparison

Engineering Selection Recommendations

The IRF830ASPBF is a direct electrical and mechanical equivalent to the IRF830AS. Both devices share identical electrical specifications across all rated parameters, including voltage, current, on-state resistance, and thermal characteristics. Both are housed in the TO-263 (D2PAK) surface mount package with identical pin configuration.

The primary distinction between the two parts is product lifecycle status and regulatory compliance:

IRF830AS: Classified as obsolete with RoHS non-compliant status. This part number is suitable only for legacy system maintenance or repair applications where original component specifications are required.

IRF830ASPBF: Classified as active product status with ROHS3 compliance. This part number is the recommended selection for new designs, production builds, and systems requiring current regulatory compliance. The ASPBF variant is supplied in tube packaging, which is standard for active production inventory.

Both parts are manufactured by Vishay Siliconix and carry identical REACH and ECCN classifications. Selection between these parts should be based on application lifecycle requirements and regulatory compliance mandates rather than electrical performance, as electrical performance is identical.

Frequently Asked Questions (FAQ)

Q: Can IRF830ASPBF be used as a direct replacement for IRF830AS in existing designs?

A: Yes. The IRF830ASPBF is electrically and mechanically identical to the IRF830AS. All electrical parameters, including voltage rating, current rating, on-state resistance, and thermal characteristics, are identical. The TO-263 (D2PAK) package geometry and pin configuration are identical, enabling direct board-level substitution without layout modification.

Q: What is the difference between IRF830AS and IRF830ASPBF?

A: The IRF830AS and IRF830ASPBF are identical in electrical specification and package type. The differences are: (1) Product status—IRF830AS is obsolete while IRF830ASPBF is active; (2) RoHS compliance—IRF830AS is RoHS non-compliant while IRF830ASPBF is ROHS3 compliant; (3) Packaging format—IRF830AS is supplied in bulk while IRF830ASPBF is supplied in tube.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical power dissipation ratings of 3.1W (Ta) and 74W (Tc), identical operating temperature range of -55°C to 150°C, and identical electrical characteristics including Rds On, gate charge, and input capacitance.

Q: What does the "ASPBF" suffix indicate?

A: The ASPBF suffix indicates the part is supplied in tube packaging format and meets ROHS3 compliance requirements. The base part number IRF830 remains the same, with the suffix denoting packaging and compliance variant.

Q: Is the TO-263 (D2PAK) package the same across both part numbers?

A: Yes. Both IRF830AS and IRF830ASPBF use the TO-263-3 (D2PAK) surface mount package with 2 leads plus tab configuration. Package dimensions, pin spacing, and thermal characteristics are identical.

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

A: IRF830ASPBF should be selected for new designs. This part is active in production, ROHS3 compliant, and represents the current manufacturing standard from Vishay Siliconix. The IRF830AS is obsolete and should be reserved for legacy system support only.

Q: Are both parts available from the same manufacturer?

A: Yes. Both IRF830AS and IRF830ASPBF are manufactured by Vishay Siliconix. Both carry identical REACH and ECCN classifications.
