Substitute Part Grouping Explanation

Substitution eligibility for the DSC06065 is determined by strict equivalence across the following parameters:

Primary Electrical Criteria:

Voltage - DC Reverse (Vr) (Max): 650 V
Current - Average Rectified (Io): 6 A or higher
Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 6 A
Reverse Recovery Time (trr): 0 ns
Technology: SiC (Silicon Carbide) Schottky

Mechanical & Thermal Criteria:

Mounting Type: Through Hole
Operating Temperature - Junction: -55°C to 175°C
Package / Case: TO-220-2 or compatible TO-220 variants

Compliance Criteria:

RoHS3 Compliant
REACH Status: Unaffected or Affected (both acceptable)
ECCN: EAR99

Substitute parts must satisfy all primary electrical criteria and maintain thermal operating range equivalence. Package variants within the TO-220 family (TO-220-2, TO-220AC, TO-247-3) are considered mechanically compatible for through-hole mounting applications where pin configuration and thermal dissipation requirements align.

Engineering Selection Recommendations

Direct Substitutes (TO-220-2 Package):

The following parts are direct substitutes for the DSC06065 with identical package configuration and electrical specifications:

UJ3D06506TS (Qorvo): Maintains 6 A current rating, 650 V reverse voltage, and TO-220-2 package. RoHS3 compliant, REACH unaffected. Reverse leakage of 40 µA at 650 V. Active product status.
IDH06G65C5XKSA2 (Infineon): CoolSiC™+ series, 6 A current rating, 650 V reverse voltage, TO-220-2 package. RoHS3 compliant, REACH unaffected. Reverse leakage of 110 µA at 650 V. Active product status.
PCDP0665G1_T0_00001 (Panjit): 6 A current rating, 650 V reverse voltage, TO-220AC package (TO-220-2 compatible). RoHS3 compliant, REACH unaffected. Reverse leakage of 50 µA at 650 V. Active product status.
S3D06065A (SMC Diode Solutions): 6 A current rating, 650 V reverse voltage, TO-220AC package (TO-220-2 compatible). RoHS3 compliant. Reverse leakage of 8 µA at 650 V. Active product status. REACH affected status noted.

Higher Current Substitute (TO-247-3 Package):

FFSH1265BDN-F085 (onsemi): Rated for 7.2 A current (exceeds 6 A requirement), 650 V reverse voltage. TO-247-3 package requires mechanical board layout modification. RoHS3 compliant, REACH unaffected. Automotive grade with AEC-Q101 qualification. Reverse leakage of 40 µA at 650 V. Active product status.

All substitute parts maintain the required thermal operating range of -55°C to 175°C junction temperature and zero reverse recovery time characteristic of silicon carbide Schottky technology. Selection between TO-220-2 variants depends on reverse leakage performance requirements and board space constraints. The TO-247-3 option provides higher current capacity at the cost of increased package footprint.

Frequently Asked Questions (FAQ)

Q: Can the FFSH1265BDN-F085 be used as a direct replacement for the DSC06065?

A: The FFSH1265BDN-F085 is electrically equivalent but uses a TO-247-3 package instead of TO-220-2. This requires different PCB mounting holes and thermal management layout. The higher 7.2 A current rating exceeds the 6 A requirement. Mechanical compatibility must be confirmed for your specific board design.

Q: What is the significance of reverse leakage current differences among the substitutes?

A: Reverse leakage current values range from 8 µA (S3D06065A) to 200 µA (DSC06065) at 650 V. Lower leakage reduces standby power dissipation and heat generation. Selection depends on application requirements for efficiency and thermal management. All values remain within acceptable ranges for silicon carbide Schottky diodes.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. REACH status varies: most are REACH unaffected, while S3D06065A is REACH affected. Both statuses are acceptable for component selection; REACH affected status indicates the part contains substances on the REACH candidate list but remains usable in most applications.

Q: What is the difference between TO-220-2 and TO-220AC packages?

A: TO-220-2 and TO-220AC refer to the same physical package configuration with two leads. The designation difference reflects manufacturer nomenclature. Both are mechanically and electrically compatible for through-hole mounting applications.

Q: Can I substitute based on current rating alone?

A: No. Substitution requires equivalence across all primary electrical criteria: 650 V reverse voltage, 1.7 V forward voltage at 6 A, zero reverse recovery time, and silicon carbide Schottky technology. Current rating of 6 A or higher is necessary but not sufficient for compatibility.

Q: Which substitute offers the lowest reverse leakage?

A: S3D06065A from SMC Diode Solutions exhibits the lowest reverse leakage at 8 µA at 650 V, compared to 200 µA for the original DSC06065. This represents a 96% reduction in leakage current.

Q: Are there inventory considerations for substitute selection?

A: Inventory levels vary significantly: UJ3D06506TS (Qorvo) has 59,318 pcs available, while DSC06065 has 892 pcs. Higher inventory availability may influence lead time and supply chain reliability for production applications.

Q: What thermal performance differences exist among substitutes?

A: All substitutes maintain the identical operating temperature range of -55°C to 175°C junction temperature. Differences in reverse leakage current and capacitance affect thermal dissipation characteristics, but thermal operating limits remain equivalent.
