FFSB0865B Equivalent & Substitute Parts

Part Overview

The FFSB0865B is a Silicon Carbide (SiC) Schottky diode rated for 650 V DC reverse voltage with 10.1 A average rectified current. This component is designed for surface mount applications in the TO-263 (D2PAK) package configuration. The part is currently in active production status with 1863 units available in new original inventory.

Substitute parts are identified when electrical characteristics, mechanical packaging, and operational parameters remain within the specified tolerances of the original component. Equivalent parts enable procurement flexibility while maintaining circuit performance and reliability requirements.

Substitute Part Grouping Explanation

Substitution of the FFSB0865B is determined by equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage must equal 650 V
Current Rating: Average rectified current must equal 10.1 A
Forward Voltage Drop: Maximum forward voltage at specified current must equal 1.7 V @ 8 A
Reverse Leakage: Current leakage at rated voltage must equal 40 µA @ 650 V
Capacitance: Junction capacitance must equal 336 pF @ 1 V, 100 kHz
Package Configuration: TO-263-3 (D2PAK) with 2 leads plus tab
Technology: SiC Schottky diode technology
Temperature Range: Operating junction temperature range -55°C to 175°C

The FFSB0865B-F085 is classified as a parametric equivalent. This substitute maintains identical electrical specifications and mechanical packaging while differing only in packaging format (Tape & Reel versus Cut Tape).

Engineering Selection Recommendations

Both the FFSB0865B and FFSB0865B-F085 are active production components manufactured by onsemi with identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements rather than functional performance.

FFSB0865B (Cut Tape Packaging): Suitable for applications requiring individual component handling, manual assembly processes, or lower-volume production runs.

FFSB0865B-F085 (Tape & Reel Packaging): Suitable for automated assembly operations, high-volume production environments, and pick-and-place machine compatibility.

Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity level) classification. The reverse recovery time specification of 0 ns applies to the FFSB0865B-F085 variant.

Frequently Asked Questions (FAQ)

Q: Can FFSB0865B-F085 be used as a direct replacement for FFSB0865B?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, voltage ratings, current ratings, forward voltage drop, reverse leakage current, capacitance, operating temperature range, and TO-263 (D2PAK) package configuration. The only difference is packaging format (Tape & Reel versus Cut Tape).

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual components on carrier tape, suitable for manual handling and lower-volume applications. Tape & Reel (TR) packaging provides components on continuous reel format, optimized for automated pick-and-place assembly equipment and high-volume production.

Q: Are there any electrical performance differences between the two part numbers?

A: No. Both FFSB0865B and FFSB0865B-F085 maintain identical specifications for voltage rating (650 V), current rating (10.1 A), forward voltage (1.7 V @ 8 A), reverse leakage (40 µA @ 650 V), capacitance (336 pF @ 1 V, 100 kHz), and operating temperature range (-55°C to 175°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Both maintain active production status.

Q: Which part should be selected for automated assembly?

A: FFSB0865B-F085 in Tape & Reel format is designed for automated pick-and-place assembly operations and high-volume manufacturing environments.

Q: Is the TO-263 (D2PAK) package identical for both parts?

A: Yes. Both parts use the TO-263-3 D2PAK package configuration with 2 leads plus tab for surface mount applications.
