Product details
Overview
DSC08A065FP from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 8 A average rectified output current, and 1.5 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 DSC08A065FP datasheet, DSC08A065FP pinout, DSC08A065FP application, or DSC08A065FP equivalent, key selection criteria include its 5 °C/W junction-to-case thermal resistance, 1.5 µA typical reverse leakage at 650 V and +25°C, positive temperature coefficient of VF, fast reverse recovery, and ITO220AC 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 on VF-ensuring inherent current sharing in parallel configurations-and maintains <230 µA IR at 650 V and +175°C, supporting reliable blocking in high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports DC-link voltages up to 400–450 V nominal in three-phase PFC and inverter applications |
| IO | 8 A - continuous conduction capability at case temperature ≤ 100°C per derating curve |
| VF (max) | 1.5 V @ 8 A, +25°C - enables lower conduction loss than comparable Si diodes, reducing thermal load |
| IR (typ) | 1.5 µA @ 650 V, +25°C - ensures minimal standby power loss in high-voltage blocking roles |
| RθJC | 5 °C/W - allows direct thermal coupling to heatsinks for efficient power dissipation in compact designs |
| QC | 19 nC @ 400 V, 200 A/µs - quantifies capacitive charge affecting EMI and snubber design in high-dV/dt switching |
| TJ range | −55°C to +175°C - enables deployment in under-hood automotive auxiliary supplies and industrial motor drives |
Pinout & Package
Package: ITO220AC (Type WX-NC), molded plastic with matte tin-plated copper leadframe, UL 94V-0 rated, 1.497 g weight. Mounting compatible with standard TO-220 heatsink hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Current entry point during forward conduction | Electrically connected to metal tab - must be isolated from heatsink unless circuit ground reference permits |
| Cathode (Lead 1) | Current exit point during forward conduction | Single bent lead; provides mechanical anchoring and solder joint reliability in tube-packaged assembly |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (QRR ≈ 0) | Eliminates switching tail current and associated losses in hard-switched converters |
| Positive temperature coefficient of VF | Enables stable parallel operation without external current-sharing resistors |
| High surge current rating (IFSM = 47 A) | Withstands transient overloads such as inrush or short-circuit events in SMPS and UPS |
| Low RθJC (5 °C/W) | Reduces thermal interface requirements and simplifies heatsink sizing for 8 A continuous loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPSC8H065D | Same 650 V / 8 A rating; RθJC = 4.5 °C/W; slightly lower VF (1.45 V typ) | Optimized for higher-frequency (>200 kHz) resonant converters due to lower CT at 40 V | Prefer when minimizing capacitive charge (QC = 15 nC) is critical for EMI control |
| Wolfspeed C4D08120D | 1200 V rating; same IO; higher VF (1.7 V max); RθJC = 6.5 °C/W | Suitable for 600–800 VDC bus systems where future voltage headroom is required | Select only if system architecture mandates 1200 V blocking margin or multi-platform reuse |
Compared with STPSC8H065D and C4D08120D, the DSC08A065FP offers the best balance of thermal resistance (5 °C/W), leakage control (1.5 µA), and cost-effective 650 V optimization for mainstream industrial PFC and inverter designs.

FAQ
Is the DSC08A065FP suitable for paralleling without external ballasting resistors?
Yes. Its positive temperature coefficient of forward voltage ensures self-balancing current distribution among paralleled units. At 8 A total load, two devices share current within ±8% at +125°C case temperature, verified per datasheet Figure 3 and thermal characterization.
What is the maximum recommended PCB copper area for thermal relief at 8 A continuous current?
A minimum 1-inch² (2.54 cm²) 2-oz copper pad is specified in Note 7 of the datasheet. With this layout and free-air convection, the device sustains 8 A up to +100°C case temperature, aligning with the derating curve in Figure 1.
Does the ITO220AC package require insulating hardware when mounted to a heatsink?
Yes. The metal tab is electrically connected to the anode. If the heatsink is grounded or at a different potential, a thermally conductive but electrically isolating pad (e.g., mica or polymer-based) must be used to prevent short circuits while maintaining thermal performance.
How does reverse leakage behave at elevated temperature and full-rated voltage?
At VR = 650 V and TJ = +175°C, typical reverse leakage is 230 µA (max 160 µA per datasheet Table "Electrical Characteristics"). This remains stable over time and supports reliable blocking in high-ambient industrial environments without thermal runaway risk.
