Product details
Overview
DSC06065 from Diodes Incorporated is a 650 V, 6 A silicon carbide Schottky diode in TO220AC (Type WX) package, optimized for high-efficiency rectification with 1.7 V max forward voltage at 6 A and 25°C, 0.3 µA typical reverse leakage at 650 V/25°C, and 15 nC total capacitive charge-used as a freewheel or blocking diode in industrial motor drivers and power inverters.
For engineers reviewing the DSC06065 datasheet, DSC06065 pinout, DSC06065 application, or DSC06065 equivalent, key selection criteria include its SiC-based low conduction loss, stable high-temperature leakage performance up to +175°C, fast reverse recovery, and compatibility with high-frequency SMPS and PFC stages requiring minimal switching loss.
Technical Context
This SiC Schottky diode operates without minority-carrier storage, eliminating reverse recovery charge and enabling zero-recovery switching in hard-switched topologies. Its positive temperature coefficient on VF ensures inherent current sharing in parallel configurations.
Rated for 650 V DC blocking and 36 A non-repetitive surge (8.3 ms half-sine), it maintains thermal resistance of 3 °C/W (junction-to-case) when mounted on a fin-type heatsink, supporting continuous operation at case temperatures up to 150°C per derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in DC-link and inverter bridge applications. |
| IO | 6 A - Average rectified forward current at TC = +25°C; usable up to ~4.5 A at TC = +125°C per derating curve. |
| VF (max) | 1.7 V @ 6 A, +25°C - Low conduction loss enables high efficiency in PFC and output rectification stages. |
| IR (typ) | 0.3 µA @ 650 V, +25°C - Ultra-low leakage supports stable blocking in high-voltage, high-temperature environments. |
| QC | 15 nC - Total capacitive charge at IF = 6 A, di/dt = 250 A/µs, VR = 400 V - determines turn-off energy loss in switching circuits. |
| RθJC | 3 °C/W - Junction-to-case thermal resistance with fin-type heatsink - enables predictable thermal design for forced-air or passive cooling. |
| TJ Range | –55°C to +175°C - Extended operating junction temperature supports under-hood and industrial ambient conditions. |
Pinout & Package
Package: TO220AC (Type WX), 3-terminal through-hole package with isolated tab (cathode-connected tab). Molded plastic housing, UL 94V-0 rated, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Anode) | Anode terminal / thermal interface | Electrically connected to anode; serves as primary heat path to heatsink; requires insulating washer if mounting to grounded metal. |
| Lead 1 (Cathode) | Cathode terminal | Main cathode connection; carries full forward current; solderable per MIL-STD-202, Method 208. |
| Lead 2 (NC) | No-connect | Unused lead; not internally connected; must remain unconnected in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| SiC Schottky construction | Zero reverse recovery charge (Qrr ≈ 0), enabling lossless turn-off and EMI reduction in high-frequency converters. |
| Positive VF temperature coefficient | Enables natural current balancing in paralleled diodes without external ballasting resistors. |
| High surge capability (IFSM = 36 A) | Withstands transient overloads in motor drive startup and UPS inverter fault conditions. |
| Green, RoHS-compliant packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); compliant with EU RoHS 2015/863/EU. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSC06A065FP | Same 650 V/6 A rating; TO220AC-3L package with improved RθJC (2.5 °C/W); lower VF (1.6 V typ @ 6 A, 25°C); recommended for new designs. | Direct drop-in replacement with enhanced thermal performance; supports higher ambient or higher-power density layouts. | Select for new designs requiring extended lifetime, tighter thermal margins, or qualification to latest Diodes reliability standards. |
| STPSC6H065D | 650 V/6 A SiC Schottky; TO220AC package; VF = 1.7 V max @ 6 A, 25°C; IR = 0.5 µA typ @ 650 V, 25°C; RθJC = 3.2 °C/W. | Slightly higher leakage and thermal resistance; validated in ST's industrial motor drive reference designs. | Choose when cross-supply sourcing is required or when leveraging ST's ecosystem support and evaluation tools. |
Compared with DSC06065, DSC06A065FP offers better thermal performance and is Diodes' designated successor, while STPSC6H065D provides second-source assurance with minor trade-offs in leakage and thermal resistance-both retain identical circuit function and footprint compatibility.

FAQ
Is DSC06065 suitable for automotive applications?
No-DSC06065 is not qualified to AEC-Q101 and is not recommended for automotive use. Diodes explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; this part lacks those qualifications and is intended for industrial and commercial power systems only.
What is the maximum allowable case temperature for continuous operation?
The DSC06065 supports continuous operation up to 150°C case temperature, as shown in Figure 1 (Forward Current Derating Curve). At TC = 150°C, IO derates to approximately 4.2 A; operation beyond this point risks exceeding the +175°C maximum junction temperature under typical thermal resistance conditions.
Does the TO220AC (Type WX) package have an electrically isolated tab?
No-the tab is electrically connected to the anode. The DSC06065 TO220AC (Type WX) uses a non-isolated tab configuration. When mounting to a heatsink, electrical isolation (e.g., mica washer + shoulder washer) is required unless the heatsink and associated circuitry are referenced to the anode potential.
Why is DSC06065 marked "not recommended for new designs"?
Diodes has superseded DSC06065 with DSC06A065FP, which features improved thermal resistance (2.5 vs. 3.0 °C/W), tighter VF distribution, and updated process controls. While DSC06065 remains available for legacy support, new designs should adopt the FP variant to ensure long-term supply, enhanced reliability, and alignment with current Diodes quality standards.
