FFSP2065B Silicon Carbide Schottky Diode Equivalent & Substitute Parts

Part Overview

The FFSP2065B is an active silicon carbide Schottky rectifier diode manufactured by onsemi, rated for 650 V DC reverse voltage and 22.5 A average rectified current in a through-hole TO-220-2 package. This component is designed for high-efficiency power conversion applications requiring fast switching characteristics and minimal reverse recovery time inherent to SiC Schottky technology.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while maintaining mechanical compatibility and compliance certifications. The FFSP2065B remains in active production; however, alternative sources may be required for supply chain continuity, inventory availability, or application-specific performance optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FFSP2065B are qualified based on the following criteria:

Voltage Rating Equivalence: Substitute parts must maintain the 650 V DC reverse voltage rating to ensure safe operation in the intended application circuit.

Current Rating Compatibility: The substitute part current rating must not fall below the application requirement. The FFSP2065B is rated for 22.5 A average rectified current. Substitute parts with equal or higher current ratings are acceptable; lower ratings require application circuit re-evaluation.

Technology Consistency: All qualified substitutes utilize SiC Schottky technology, ensuring zero reverse recovery time and comparable switching performance characteristics.

Package Mechanical Compatibility: Substitute parts must use the TO-220-2 package or equivalent mechanical footprint to ensure direct board-level compatibility without layout modification.

Forward Voltage Characteristics: Forward voltage drop at rated current must be specified to ensure conduction loss calculations remain valid.

Compliance Alignment: Substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

The PCDP2065G1_T0_00001 meets these criteria with the exception of current rating, which is specified at 20 A versus the 22.5 A rating of the FFSP2065B.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The FFSP2065B remains the preferred component for applications requiring the full 22.5 A current rating. This part is active in production with 1549 units in current inventory stock.

Substitute Selection Criteria: The PCDP2065G1_T0_00001 from Panjit International Inc. is electrically compatible for applications where the average rectified current requirement does not exceed 20 A. This substitute maintains voltage rating, forward voltage characteristics, and switching speed equivalence. The substitute is also ROHS3 compliant and maintains the same operating temperature range.

Leakage Current Consideration: The PCDP2065G1_T0_00001 exhibits reverse leakage current of 120 µA at 650 V, compared to 40 µA for the FFSP2065B. Applications with stringent leakage current specifications should retain the FFSP2065B.

Compliance Status: Both parts satisfy ROHS3 compliance and REACH unaffected status, permitting use in regulated markets without additional certification requirements.

Inventory Availability: The PCDP2065G1_T0_00001 is available with 2848 units in current inventory stock, providing supply chain flexibility when FFSP2065B availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can the PCDP2065G1_T0_00001 directly replace the FFSP2065B in all applications?

A: Direct replacement is possible only in applications where the average rectified current requirement does not exceed 20 A. The PCDP2065G1_T0_00001 is rated for 20 A, while the FFSP2065B is rated for 22.5 A. Applications operating at or above 20 A require the FFSP2065B to maintain design margin.

Q: What is the significance of the reverse leakage current difference?

A: The PCDP2065G1_T0_00001 exhibits 120 µA reverse leakage at 650 V, compared to 40 µA for the FFSP2065B. This 3× difference may impact standby power consumption or leakage-sensitive circuit performance. Applications with leakage current budgets should verify compatibility before substitution.

Q: Are both parts mechanically compatible with TO-220-2 footprints?

A: Yes. Both the FFSP2065B and PCDP2065G1_T0_00001 use the TO-220-2 package, ensuring mechanical and thermal interface compatibility without PCB layout modification.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for regulated markets and applications.

Q: What is the forward voltage drop difference between these parts?

A: Both parts specify 1.7 V maximum forward voltage at 20 A, ensuring equivalent conduction loss characteristics in power conversion circuits.

Q: Can the PCDP2065G1_T0_00001 be used in high-temperature applications?

A: Yes. The PCDP2065G1_T0_00001 maintains the same operating temperature range as the FFSP2065B, -55°C to 175°C junction temperature, supporting equivalent thermal performance.
