Product details
Overview
DSC06A065 from Diodes Incorporated is a 650 V, 6 A silicon carbide Schottky diode in TO220AC (Type WX) package, delivering 1.5 V max forward voltage at 6 A and 25°C, 0.4 µA typical reverse leakage at 650 V/25°C, and 16 nC total capacitive charge - optimized for high-efficiency PFC stages and industrial inverters.
For engineers reviewing the DSC06A065 datasheet, DSC06A065 pinout, DSC06A065 application, or DSC06A065 equivalent, key selection criteria include its 650 V blocking rating, low VF temperature coefficient, 175°C maximum junction temperature, and robust surge capability (38 A IFSM) in non-automotive industrial power conversion designs.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency switching topologies. Its zero reverse recovery charge (Qrr ≈ 0) eliminates switching losses associated with minority-carrier storage, while its positive VF temperature coefficient enables inherent current sharing in parallel configurations.
The device operates across -55°C to +175°C with RθJC = 5°C/W and RθJL = 3°C/W, enabling direct mounting on aluminum heatsinks or copper pads per JESD-51 test conditions. Its 272 pF junction capacitance at 0.1 V reverse bias supports stable snubberless operation in 50–100 kHz PFC and inverter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 V AC input PFC and 600 V DC bus inverters without derating. |
| IO | 6 A average - Supports continuous conduction mode (CCM) PFC output rectification up to 1 kW at 100 kHz. |
| VF Max | 1.5 V @ 6 A, 25°C - Reduces conduction loss by ~40% vs. comparable Si FRD (VF ≈ 2.5 V). |
| IR Typ | 0.4 µA @ 650 V, 25°C - Ensures minimal standby power loss in offline SMPS standby circuits. |
| QC | 16 nC - Low capacitive charge minimizes turn-off losses and EMI in hard-switched boost converters. |
| RθJC | 5 °C/W - Allows thermal design with ≤30 W dissipation using standard 35 mm × 22 mm × 16 mm Al heatsink. |
| TJ Max | +175°C - Permits operation in sealed industrial enclosures without forced air cooling. |
Pinout & Package
Package: TO220AC (Type WX), 3-terminal through-hole package with isolated tab (cathode-connected tab). Molded plastic body, matte tin-plated copper leadframe, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current terminal | Connected to AC or switching node; requires minimum 1.5 mm creepage clearance to ground. |
| Cathode (Lead 2) | Output current terminal | Electrically tied to metal tab; must be insulated from heatsink unless system common-cathode topology. |
| Tab (Cathode) | Thermal & electrical cathode path | Primary heat transfer surface; electrically identical to Lead 2; requires dielectric pad or mica insulator if heatsink grounded. |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (Qrr) | Eliminates turn-off switching loss and associated EMI in hard-switched PFC and inverter legs. |
| Positive VF temperature coefficient | Enables stable parallel operation without external current-sharing resistors or active balancing. |
| High surge current capability (IFSM = 38 A) | Withstands 10 ms half-sine surges during cold-start or overload in UPS and motor drive applications. |
| Low junction-to-case thermal resistance (5 °C/W) | Reduces thermal interface material dependency and simplifies heatsink sizing for 30 W+ dissipation. |
| RoHS 3 / Halogen-free / "Green" compliant | Meets IPC-1752A material declaration requirements for automotive and industrial OEM supply chains. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon carbide Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPSC6H065D | Same 650 V/6 A rating; VF = 1.7 V max @ 6 A/25°C; RθJC = 4.5 °C/W; TO220AC package. | Higher VF increases conduction loss by ~15% at full load; slightly better thermal resistance. | Select when marginally lower thermal resistance outweighs higher VF penalty in thermally constrained layouts. |
| WOLFSPEED C4D06120A | 1200 V rating; 6 A IO; VF = 1.8 V max @ 6 A/25°C; TO247-2L package; RθJC = 2.5 °C/W. | Over-spec'd voltage rating adds cost and capacitance; unsuitable for 650 V systems without redesign. | Choose only if future-proofing for 1200 V bus or requiring TO247 mechanical compatibility. |
Compared with STPSC6H065D and C4D06120A, DSC06A065 offers the lowest VF among 650 V/6 A SiC diodes in TO220AC, making it optimal for efficiency-critical PFC and inverter rectification where thermal headroom exists but conduction loss dominates.

FAQ
Is DSC06A065 qualified for automotive applications?
No. DSC06A065 is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949-certified manufacturing traceability. It is intended for industrial, computing, and telecom applications. For automotive-grade alternatives, contact Diodes Incorporated directly to request AEC-Q101-compliant variants such as the DSC06A065Q series.
What is the recommended heatsink mounting method for DSC06A065?
Mount the TO220AC tab directly to an aluminum heatsink using a thermally conductive, electrically isolating pad (e.g., Sil-Pad 2000) and torque screw to 0.5–0.7 N·m. Avoid thermal paste alone - the tab is cathode-connected, so electrical isolation is mandatory unless the heatsink is floating or system-common cathode.
Does DSC06A065 require a snubber circuit in 100 kHz PFC applications?
Typically no. With near-zero Qrr and 272 pF junction capacitance at low VR, DSC06A065 exhibits minimal voltage overshoot and ringing in well-layout boost PFC circuits. Snubbers may still be needed only if PCB layout introduces excessive stray inductance (>20 nH) between diode and bulk capacitor.
How does VF drift with temperature, and why does it matter?
VF increases linearly with junction temperature (positive TC), reaching ~1.67 V at 175°C/6 A. This behavior prevents thermal runaway in parallel configurations and simplifies current-sharing design - unlike Si diodes with negative VF TC that require external balancing components.
