IRF820STRL Equivalent & Substitute Parts

Part Overview

The IRF820STRL is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 500V drain-to-source voltage with 2.5A continuous drain current. The device is housed in a TO-263 (D2PAK) surface mount package and is designed for applications requiring high-voltage switching and power dissipation up to 50W at the case temperature.

The IRF820STRL carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity, supply chain reliability, and access to components with active manufacturing support and current compliance certifications.

• On-State Resistance (Rds On Max): 3Ω @ 1.5A, 10V
• Gate Threshold Voltage (Vgs(th) Max): 4V @ 250µA
• Gate Charge (Qg Max): 24 nC @ 10V
• Input Capacitance (Ciss Max): 360 pF @ 25V
• Power Dissipation (Max): 3.1W (Ta), 50W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package Type: TO-263 (D2PAK), Surface Mount
• Gate Voltage (Vgs Max): ±20V
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)

All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the main part number. Differences in product status and compliance certifications are noted separately.

Parameter Comparison

Engineering Selection Recommendations

The IRF820STRL is functionally equivalent to both IRF820STRLPBF and IRF820STRRPBF at the electrical and mechanical level. All three parts share identical specifications for voltage rating, current capacity, on-state resistance, gate characteristics, and thermal performance.

The primary distinctions between these parts are product status and compliance certifications:

IRF820STRLPBF and IRF820STRRPBF are both active products with ROHS3 compliance certification. These parts are recommended for new designs and applications requiring current manufacturing support and regulatory compliance documentation. Both are available in Tape & Reel packaging, suitable for automated assembly processes.

IRF820STRL carries obsolete product status and RoHS non-compliant certification. This part number is suitable only for legacy system maintenance or repair applications where the original part specification must be maintained. Availability is limited to existing inventory.

For applications requiring new component procurement, regulatory compliance, or long-term supply chain assurance, IRF820STRLPBF or IRF820STRRPBF are the appropriate selections. The choice between these two active alternatives depends on packaging requirements and supplier availability.

Frequently Asked Questions (FAQ)

Q: Are IRF820STRLPBF and IRF820STRRPBF electrically identical to IRF820STRL?

A: Yes. All three parts share identical electrical specifications including Vdss (500V), Id (2.5A), Rds On (3Ω), gate threshold voltage, gate charge, input capacitance, and power dissipation ratings. They are mechanically compatible in the same TO-263 (D2PAK) package.

Q: What is the difference between IRF820STRLPBF and IRF820STRRPBF?

A: Both parts are electrically and mechanically identical. The difference lies in packaging format and supplier designation. Both are active products with ROHS3 compliance. Selection between them depends on supplier availability and internal part numbering conventions.

Q: Can IRF820STRLPBF or IRF820STRRPBF be used as direct replacements for IRF820STRL?

A: Yes. The substitute parts are direct replacements from an electrical and mechanical standpoint. They fit the same PCB footprint, operate within identical voltage and current ranges, and maintain the same thermal characteristics. No circuit modifications are required.

Q: Why is IRF820STRL marked as obsolete?

A: The IRF820STRL is an older product designation. Vishay Siliconix has transitioned to active production of IRF820STRLPBF and IRF820STRRPBF, which carry current compliance certifications and manufacturing support.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts meet the Restriction of Hazardous Substances Directive 3 requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. This certification is required for many commercial and industrial applications.

Q: Are the substitute parts available in the same packaging options?

A: IRF820STRLPBF and IRF820STRRPBF are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. The original IRF820STRL is available in bulk packaging. Both packaging formats are compatible with standard PCB assembly processes; the choice depends on production volume and assembly equipment.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. From a circuit design perspective, IRF820STRLPBF and IRF820STRRPBF are direct functional equivalents to IRF820STRL. No design changes, simulation updates, or performance re-qualification are necessary for substitution.
