Product details
Overview
DSC08065D1 from Diodes Incorporated is an 8 A, 650 V silicon carbide Schottky diode in TO252 (Type WX) package, designed for high-efficiency power conversion. It delivers low forward voltage (1.7 V max at 8 A, 25°C), ultra-low reverse leakage (0.65 µA typ at 650 V, 25°C), and fast recovery-enabling use as a rectifier or freewheel diode in PFC stages of industrial SMPS.
For engineers reviewing the DSC08065D1 datasheet, DSC08065D1 pinout, DSC08065D1 application, or DSC08065D1 equivalent, key selection criteria include its SiC-specific thermal stability (–55°C to +175°C operation), junction-to-case thermal resistance (3°C/W), and surge capability (48 A non-repetitive peak).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-temperature switching applications. Its zero reverse recovery charge (Qr ≈ 0) eliminates switching losses associated with minority-carrier storage, while its positive temperature coefficient on VF enables inherent current sharing in parallel configurations.
The device operates with stable leakage up to 175°C (IR = 700 µA max at 650 V, 175°C) and exhibits low junction capacitance (240–295 pF at 1–40 V), supporting high dV/dt immunity and reduced EMI in hard-switched inverters and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Blocks DC bus voltages up to 650 V in 400 V nominal systems with margin. |
| IO | 8 A continuous - Supports sustained conduction in compact PFC boost stages without forced cooling. |
| VF (max) | 1.7 V @ 8 A, 25°C - Reduces conduction loss vs. Si diodes (~0.5 V lower), improving efficiency by ~0.8% in 3 kW PFC. |
| IR (typ) | 0.65 µA @ 650 V, 25°C - Enables stable blocking in high-impedance gate drive or sensing circuits. |
| RθJC | 3 °C/W - Allows direct mounting to heatsink for thermal management in space-constrained industrial enclosures. |
| IFSM | 48 A (8.3 ms half-sine) - Withstands inrush currents during UPS startup or motor phase commutation. |
| QC | 17 nC - Low capacitive charge minimizes turn-off energy loss in high-frequency (>100 kHz) converters. |
Pinout & Package
Package: TO252 (Type WX), surface-mount, 3-terminal plastic package with exposed cathode pad for thermal and electrical performance. Dimensions per Diodes DS44283 Rev. 4–3: D = 6.10 mm, E = 6.60 mm, H = 10.10 mm, L = 1.50 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry terminal | Connected to AC input or switching node; requires low-inductance layout to minimize voltage overshoot. |
| Cathode (Lead 2 & Exposed Pad) | Current exit terminal / Thermal path | Electrically and thermally tied to output rail; pad must be soldered to ≥100 mm² copper pour for RθJC compliance. |
| Source/Drain Tab (Lead 3) | Not applicable | TO252 (WX) has only two functional terminals; Lead 3 is mechanical support, not electrically active. |
Key Features
| Feature | Design Value |
|---|---|
| SiC Schottky architecture | Zero reverse recovery charge (Qr ≈ 0) eliminates tail current, enabling >200 kHz switching without snubbers. |
| Positive VF temperature coefficient | Enables natural current balancing in parallel-connected diodes without external ballasting resistors. |
| High-temperature leakage stability | IR remains ≤700 µA at 650 V and 175°C-critical for uncooled UPS or solar inverter derating. |
| Robust surge rating | 48 A IFSM supports repeated motor start-up surges in industrial drives without degradation. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (≤900 ppm Br/Cl, ≤1000 ppm Sb) meets automotive and industrial environmental mandates. |
Applications
| Power Factor Correction (PFC) | Industrial Motor Drives |
|---|---|
Use Scenario: Boost-stage output rectification in 3 kW telecom rectifiers. IC Role / Device Role / Timing Role: Freewheel diode conducting during MOSFET off-time; handles 8 A average current at 100–200 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSC08A065D1-13 | Same VRRM, IO, and TO252 package; improved VF (1.6 V max @ 8 A, 25°C) and lower QC (15 nC). | Optimized for next-gen 200+ kHz PFC designs requiring tighter efficiency margins. | Select for new designs; DSC08065D1 is not recommended for new designs per Diodes notice. |
| STPSC8H065D | 650 V, 8 A, TO220AC package; higher VF (1.8 V max), larger RθJC (4.5°C/W), no exposed cathode pad. | Suitable for through-hole legacy systems where PCB rework is constrained. | Choose only when TO220 footprint compatibility is mandatory; thermal performance is 50% worse than DSC08065D1. |
Compared with DSC08A065D1-13, this part offers slightly higher conduction loss and capacitive charge but shares identical thermal design rules and layout; versus STPSC8H065D, it provides superior thermal dissipation and surface-mount integration at the cost of leaded assembly compatibility.

Manufacturer
Diodes Incorporated is a global semiconductor company specializing in discrete, analog, and mixed-signal ICs, with manufacturing certified to IATF 16949 and quality systems aligned to AEC-Q standards.
This device belongs to Diodes' DSC-series SiC Schottky diode family, engineered for high-efficiency, high-temperature power conversion in industrial and renewable energy systems-not automotive-qualified by default.
FAQ
Is DSC08065D1 qualified for automotive applications?
No. DSC08065D1 is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949-controlled change management. Diodes explicitly states that automotive-grade variants require direct contact with their representatives for AEC-Q101-compliant alternatives like the DSC08A065D1Q-13.
What is the maximum allowable case temperature for continuous operation?
The absolute maximum case temperature is +175°C, verified by thermal testing per JESD-51. At 175°C, the device maintains 0.65 µA typical leakage at 650 V, but derating curves show IO drops to ~4.5 A at TC = 125°C and ~2.2 A at TC = 150°C per Figure 1.
Can DSC08065D1 be paralleled for higher current handling?
Yes-its positive temperature coefficient on VF enables stable current sharing without external resistors. Parallel operation requires matched layout symmetry, equal trace inductance (<5 nH difference), and shared thermal coupling via common heatsink area to avoid thermal runaway.
Does the TO252 (Type WX) package support automated optical inspection (AOI)?
Yes. The TO252 (Type WX) outline features defined solder mask openings, coplanar leads, and a flat exposed cathode pad compatible with standard AOI systems. Diodes confirms IPC-7351B-compliant land patterns and recommends 100% solder paste coverage on the thermal pad for void control.
