Product details
Overview
DSC08065FP from Diodes Incorporated is an 8A, 650V silicon carbide Schottky diode in ITO220AC (Type WX-NC) package, designed for high-efficiency rectification with VF ≤ 1.7 V at 8 A and 25°C, IR ≤ 0.61 µA at 650 V and 25°C, and RθJC = 6°C/W. It serves as a freewheel or blocking diode in industrial motor drives and UPS systems where high-temperature stability and low switching loss are critical.
For engineers reviewing the DSC08065FP datasheet, DSC08065FP pinout, DSC08065FP application, or DSC08065FP equivalent, key selection factors include its SiC-based low reverse recovery charge (QC = 17 nC), positive temperature coefficient on VF, 175°C maximum junction temperature, and robust surge capability (IFSM = 48 A).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-temperature power conversion stages. Its zero reverse recovery charge eliminates switching tail current, reducing EMI and enabling higher-frequency operation in PFC and inverter topologies.
The device exhibits stable leakage performance up to 175°C (IR = 700 µA at 650 V and 175°C) and maintains forward voltage consistency across temperature due to its positive VF temperature coefficient - simplifying thermal design in compact heatsink layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Withstands DC blocking and transient reverse voltages up to 650 V without breakdown. |
| IO (TC = 25°C) | 8 A - Continuous average forward current rating at case temperature of 25°C. |
| VF (Max) | 1.7 V @ 8 A, 25°C - Low conduction loss enables >98% efficiency in high-current rectifier legs. |
| IR (Typ) | 0.61 µA @ 650 V, 25°C - Ultra-low leakage supports stable operation in high-impedance PFC hold-up circuits. |
| QC | 17 nC - Near-zero reverse recovery charge minimizes switching losses and snubber requirements. |
| RθJC | 6 °C/W - Enables direct mounting to heatsinks for thermal management in space-constrained inverters. |
| TJ Range | –55°C to +175°C - Supports operation in harsh environments including industrial motor control enclosures. |
Pinout & Package
Package: ITO220AC (Type WX-NC), single-sided heat-dissipating plastic package with exposed copper tab for direct thermal interface. Dimensions per Diodes DS44308 Rev. 5–3: D = 14.95–15.95 mm, E = 10.00–10.40 mm, L = 13.00–13.70 mm, weight ≈ 1.497 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Current entry point under forward bias | Exposed metal tab serves as both electrical anode and primary thermal path to heatsink. |
| Cathode (Lead) | Current exit point under forward bias | Single lead-form cathode terminal; solderable matte tin finish over copper leadframe per MIL-STD-202. |
Key Features
| Feature | Design Value |
|---|---|
| Low conduction & switching loss | VF ≤ 1.7 V @ 8 A/25°C + QC = 17 nC enables >2% system efficiency gain vs. Si FRD in 100 kHz PFC stages. |
| High-temperature operation | Rated TJ up to +175°C with IR = 700 µA @ 650 V/175°C - maintains reliability in sealed motor drive cabinets. |
| Positive VF temperature coefficient | VF increases with temperature - enables inherent current sharing in parallel configurations without external ballasting. |
| Fast reverse recovery | Zero reverse recovery time (Qrr ≈ 0) - eliminates turn-off switching spikes and reduces EMI filter size by ≥30%. |
| Robust surge capability | IFSM = 48 A (8.3 ms half-sine) - withstands inrush and fault currents in UPS battery charging circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSC08A065F | Same 650 V/8 A rating; improved VF (1.52 V typ @ 8 A/25°C) and lower RθJC (5.5°C/W); RoHS-compliant, halogen-free. | Direct drop-in replacement with enhanced thermal and conduction performance; recommended for new designs per Diodes notice. | Select for new designs requiring higher efficiency or tighter thermal margins; pinout and footprint identical. |
| STPSC8H065D | 650 V/8 A SiC Schottky; VF = 1.7 V max @ 8 A/25°C; RθJC = 6.5°C/W; TO-220AC package with different leadform spacing. | Compatible functionally but requires PCB layout revision due to non-identical lead pitch and tab geometry. | Use only when DSC08065FP is unavailable and mechanical redesign is acceptable; verify heatsink interface compatibility. |
Compared with DSC08065FP, DSC08A065F offers lower conduction loss and thermal resistance for improved power density, while STPSC8H065D provides second-source availability at the cost of board-level redesign effort and slightly higher thermal impedance.

FAQ
Is DSC08065FP qualified for automotive applications?
No. DSC08065FP is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949 manufacturing certification. Diodes explicitly states that automotive-grade variants require direct engagement with their sales team for AEC-Q101-compliant alternatives such as the DSC08A065F-AU.
What is the thermal interface requirement for the ITO220AC tab?
The anode tab must be mounted to a flat, clean heatsink surface using thermally conductive paste or pad; torque on mounting screw should be 0.5–0.7 N·m. Per DS44308, thermal resistance drops to 6°C/W only when mounted on specified aluminum/copper heatsink configuration in free air.
Can DSC08065FP be paralleled for higher current handling?
Yes - its positive temperature coefficient on VF enables natural current sharing. Parallel operation requires matched layout symmetry, identical thermal paths, and individual current-sense resistors for startup balancing; derate total IO by 15% for reliability.
Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGNS"?
Diodes has superseded DSC08065FP with DSC08A065F, which features improved VF (1.52 V typ), lower RθJC (5.5°C/W), and updated green material compliance. The notice reflects obsolescence planning, not functional failure - existing designs may continue using DSC08065FP under standard product lifecycle terms.
