Product details
Overview
DSC08C065FP from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 8 A average rectified output current, and 1.7 V maximum forward voltage at 8 A and +25°C. It serves as a high-efficiency rectifier or freewheeling diode in power conversion stages requiring low conduction loss and stable high-temperature operation, such as PFC circuits and industrial inverters.
For engineers reviewing the DSC08C065FP datasheet, DSC08C065FP pinout, DSC08C065FP application, or DSC08C065FP equivalent, key selection criteria include its 13 °C/W junction-to-case thermal resistance, 1.1 µA typical reverse leakage at 650 V and +25°C, positive temperature coefficient of VF, fast reverse recovery, and ITO220AC (Type WX) package compatibility with standard heatsink mounting.
Technical Context
This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and near-zero switching loss in hard-switched topologies. Its wide-bandgap material delivers stable performance up to +175°C junction temperature with minimal increase in forward voltage drift.
The device exhibits a positive temperature coefficient of forward voltage (VF), simplifying parallel operation without current-sharing resistors. Its low junction capacitance (273 pF at 0.1 V) and total capacitive charge (24 nC at 400 V) support high-frequency operation in resonant and soft-switching converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - blocks full-line transients in 400 VAC input PFC and 600 VDC bus systems |
| IO (TC = +25°C) | 8 A - continuous conduction capability at standard heatsink interface conditions |
| VF (Max) | 1.7 V @ 8 A, +25°C - enables <13.6 W conduction loss per diode at rated current |
| IR (Typ) | 1.1 µA @ 650 V, +25°C - ensures negligible standby leakage in high-voltage hold-off applications |
| RθJC | 13 °C/W - allows direct thermal path to heatsink with predictable junction temperature rise |
| IFSM | 38 A (10 ms half-sine) - withstands inrush and fault currents in motor drive DC links |
| QC | 24 nC @ 400 V - reduces turn-off switching loss and EMI generation in high-dV/dt environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D08065E (Wolfspeed) | Same 650 V/8 A rating; TO-220AC package; VF = 1.8 V @ 8 A, +25°C; RθJC = 12.5 °C/W | Slightly higher VF increases conduction loss by ~0.8 W at full load; identical thermal performance | Preferred where legacy Wolfspeed qualification or supply chain diversification is required |
| SS8P6M (ON Semiconductor) | 650 V/8 A; TO-220AC; VF = 1.75 V @ 8 A, +25°C; RθJC = 14.5 °C/W; IR = 2.5 µA @ 650 V, +25°C | Higher thermal resistance requires larger heatsink area; 2.3× higher leakage impacts high-temperature hold-off margin | Acceptable for cost-sensitive, lower-ambient-temperature designs with relaxed thermal budgets |
Compared with C3D08065E and SS8P6M, DSC08C065FP offers the lowest combination of VF and RθJC among 650 V/8 A SiC diodes in ITO220AC, delivering superior thermal efficiency and leakage stability at elevated temperatures-critical for compact, high-power-density industrial converters.

FAQ
Is DSC08C065FP suitable for automotive applications?
No-DSC08C065FP is not AEC-Q101 qualified. While it operates from -55°C to +175°C and meets RoHS/Green requirements, Diodes Incorporated explicitly states that automotive-grade versions require separate qualification (e.g., PPAP, IATF 16949 manufacturing) and must be requested directly via their automotive team. This part is intended for industrial, computing, and telecom power systems.
What is the maximum recommended case temperature for continuous operation?
The absolute maximum case temperature is +175°C, but the Forward Current Derating Curve (Figure 1) shows rated 8 A IO only at TC ≤ +25°C. At +100°C case temperature, the device supports ~4.5 A average current. Designers must use RθJC = 13 °C/W and ambient/heatsink conditions to calculate actual junction temperature and ensure TJ ≤ +175°C under worst-case load and airflow.
Does DSC08C065FP have a built-in thermal protection feature?
No-DSC08C065FP is a passive two-terminal device with no integrated thermal sensing or shutdown circuitry. Thermal management relies entirely on external mechanical design: heatsink selection, mounting pressure, thermal interface material, and PCB copper area. The specified RθJC and derating curve provide the necessary data to implement safe thermal design without additional protection circuitry.
Can DSC08C065FP be paralleled with other SiC diodes for higher current handling?
Yes-its positive temperature coefficient of forward voltage enables inherently stable current sharing when paralleled with identical units. However, layout symmetry (equal trace inductance/resistance), matched thermal paths, and identical mounting torque on the metal tab are essential. Diodes recommends using no more than two devices in parallel unless validated with measured thermal and current imbalance under full-load, high-temperature conditions.
