Substitute Part Grouping Explanation

Substitution of the LSIC2SD065C06A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage rating: 650V DC reverse voltage (Vr)
Package type: TO-252-3 DPAK (2 Leads + Tab) surface mount configuration
Technology: SiC (Silicon Carbide) Schottky diode
Operating temperature range: -55°C to 175°C junction temperature
Compliance: ROHS3 compliant

Current Rating Consideration: The LSIC2SD065C06A operates at 18.5A average rectified current. Substitute parts are grouped by current capacity: lower-rated devices (8A to 13.5A) provide reduced current capability, while higher-rated devices (20A to 32A) provide increased current capacity. Selection depends on circuit requirements.

Forward Voltage Characteristic: Forward voltage (Vf) at specified current levels remains consistent across the SiC Schottky technology platform at 1.7V to 1.8V, ensuring thermal and efficiency characteristics remain within acceptable design margins.

All substitute parts listed are manufactured by Wolfspeed, Inc. (Z-Rec® series) or SMC Diode Solutions, maintaining SiC Schottky technology and identical package specifications.

Engineering Selection Recommendations

For Direct Replacement (18.5A Equivalent Current Capacity):

The C3D06065E and C3D08065E provide current ratings closest to the original 18.5A specification. C3D08065E (25.5A) is the preferred active substitute, offering higher current capacity margin with identical 650V voltage rating, TO-252-3 DPAK package, and active product status. C3D06065E (20A) is also suitable but carries "Not For New Designs" status, limiting its use to maintenance applications only.

For Current-Reduced Applications:

When circuit design permits lower current operation, C3D04065E or C3D04065E-TR (13.5A) provide active alternatives with full compliance and unlimited moisture sensitivity level (MSL 1). These parts are suitable for applications where the 18.5A capacity is not required.

Packaging Consideration:

Wolfspeed Z-Rec® series parts are available in two packaging formats: Tube (standard) and Cut Tape (CT) & Digi-Reel® (-TR suffix). Selection depends on procurement and assembly requirements. Both formats maintain identical electrical specifications and compliance certifications.

Compliance and Regulatory Status:

All recommended substitute parts maintain ROHS3 compliance and REACH affected status, matching the original component's regulatory profile. Operating temperature range (-55°C to 175°C junction) is consistent across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can C3D04065E replace LSIC2SD065C06A in all applications?

A: C3D04065E is electrically compatible in terms of voltage rating (650V), package type (TO-252-3 DPAK), and technology (SiC Schottky). However, its 13.5A current rating is lower than the original 18.5A specification. Substitution is valid only if circuit design confirms that maximum current demand does not exceed 13.5A.

Q: What is the difference between C3D08065E and C3D08065E-TR?

A: Both parts are identical in electrical specifications and package type. The difference is packaging format: C3D08065E is supplied in Tube packaging, while C3D08065E-TR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on procurement method and assembly line requirements.

Q: Why is C3D06065E marked "Not For New Designs"?

A: C3D06065E carries this status from the manufacturer, indicating it is available for existing production support but should not be selected for new circuit designs. For new applications, C3D08065E (25.5A) is the recommended active alternative.

Q: Are all substitute parts pin-compatible with LSIC2SD065C06A?

A: Yes. All substitute parts use the TO-252-3 DPAK package with 2 leads plus tab configuration (SC-63), ensuring identical PCB footprint and pin assignment compatibility.

Q: What is the impact of forward voltage differences between parts?

A: Forward voltage (Vf) ranges from 1.7V to 1.8V across all parts at their respective rated currents. This variation is within normal SiC Schottky diode characteristics and does not require circuit redesign. Thermal performance and efficiency remain consistent.

Q: Can SICRD6650 from SMC Diode Solutions be used as a substitute?

A: SICRD6650 is electrically and mechanically compatible (650V, 6A, TO-252-3 DPAK, SiC Schottky). However, its 6A current rating is significantly lower than the original 18.5A specification. Substitution is valid only for applications with maximum current requirements below 6A.

Q: What is the reverse recovery time (trr) significance for these diodes?

A: The LSIC2SD065C06A and most Wolfspeed Z-Rec® substitutes specify 0 ns reverse recovery time, indicating true zero-recovery SiC Schottky behavior. Some C3D02065E-TR and C3D03065E-TR variants specify ≤500 ns fast recovery, which remains within acceptable performance for most applications but should be verified against specific circuit switching requirements.
