SCS110KGC Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor SCS110KGC is a silicon carbide (SiC) Schottky diode in the "Diodes, Rectifiers" category, provided in a TO-220-2 through-hole package. It is specified for 1200 V reverse voltage, 10A average rectified current, and 1.75 V forward voltage at 10 A, with zero recovery time. The product status is "Obsolete," making it necessary to find alternative models to ensure continuity in designs and maintenance where SCS110KGC is specified.

Engineering Selection Recommendations

Selection of substitute diodes for Rohm SCS110KGC must be based on product and environmental compliance criteria. Each of the listed substitute part numbers (IDH05G120C5XKSA1, C4D08120A, C4D10120A, C4D20120A) has active product status, ROHS3 compliance, REACH Unaffected status, and is designated as MSL 1 (Unlimited). These criteria align with the requirements for continuity in regulated or environmentally controlled applications.

Frequently Asked Questions (FAQ)

Q: What criteria are used to qualify a substitute for SCS110KGC?
A: Substitutes must match the SCS110KGC in technology (SiC Schottky), voltage rating (1200 V), through-hole mounting, TO-220 package compatibility, reverse recovery characteristics, and compliance standards (ROHS3, REACH).

Q: Are all substitute parts mechanically compatible with the SCS110KGC package?
A: All listed substitutes use TO-220-2 or its direct variant, matching the mechanical envelope for through-hole applications.

Q: How is electrical compatibility ensured between SCS110KGC and substitutes?
A: Voltage, current, recovery time, leakage, and capacitance parameters are directly compared. Each substitute meets or exceeds the 1200 V rating and zero recovery time specification.

Q: What about compliance certifications?
A: Every listed substitute part is ROHS3 Compliant, REACH Unaffected, and rated at Moisture Sensitivity Level 1 (Unlimited), aligning with industry compliance requirements.

Q: Is there any difference in performance such as speed or reverse recovery?
A: All substitutes specify 0 ns reverse recovery time and are SiC Schottky, matching the performance profile of SCS110KGC within the allowed parameter set.
