Product details
Overview
DSC04065FP from Diodes Incorporated is a 650V, 4A silicon carbide Schottky diode in ITO220AC (Type WX-NC) package, designed for high-efficiency rectification with low forward voltage (1.7 V max at 4 A, 25°C), ultra-low reverse leakage (1.35 µA typ at 650 V, 25°C), and fast recovery in power factor correction and industrial motor drive circuits.
For engineers reviewing the DSC04065FP datasheet, DSC04065FP pinout, DSC04065FP application, or DSC04065FP equivalent, key selection criteria include thermal resistance (RθJC = 7 °C/W), surge capability (IFSM = 28 A), junction temperature range (–55 to +175°C), and SiC-specific advantages over silicon diodes in high-frequency, high-temperature switching.
Technical Context
This SiC Schottky diode operates without minority-carrier storage, eliminating reverse recovery charge (Qrr ≈ 0) and enabling zero-loss switching transitions. Its positive temperature coefficient on VF ensures inherent current sharing in parallel configurations.
Rated for continuous operation up to +175°C case temperature, it delivers stable leakage performance (<550 µA at 650 V, 175°C) and maintains low capacitive charge (QC = 14 nC typical) across wide voltage and temperature ranges-critical for high-frequency SMPS and inverter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - blocks full DC bus voltage in 400 V AC-input PFC stages and 600 V-class inverters |
| IO | 4 A - average rectified output current at TC = 25°C, derates linearly to ~2.2 A at 125°C |
| VF (max) | 1.7 V @ 4 A, 25°C - reduces conduction loss vs. Si FRD (typ. 2.2–2.8 V), improving efficiency by ≥0.5% in 3 kW PFC |
| IR (typ) | 1.35 µA @ 650 V, 25°C - enables stable blocking in high-impedance gate-drive or sensing paths |
| QC | 14 nC typical - limits turn-off energy loss in hard-switched topologies operating >100 kHz |
| RθJC | 7 °C/W - allows direct mounting to heatsink for thermal management in compact industrial power modules |
| TJ Range | –55 to +175°C - supports under-hood automotive auxiliary supplies and high-temp industrial control cabinets |
Pinout & Package
Package: ITO220AC (Type WX-NC), 3-terminal molded plastic package with matte tin-plated copper leadframe; UL 94V-0 rated; weight ≈1.497 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point during forward conduction | Connected to high-side switch node in boost PFC or inverter leg; requires low-inductance layout |
| Cathode (Lead 2) | Current exit point during forward conduction | Common return path to DC bus capacitor; thermally coupled to heatsink via tab |
| Tab (Case) | Electrically connected to cathode | Provides primary thermal path (RθJC = 7 °C/W); must be electrically isolated if cathode is not at chassis ground |
Key Features
| Feature | Design Value |
|---|---|
| SiC Schottky architecture | Zero reverse recovery charge (Qrr ≈ 0), eliminating switching loss spikes and EMI from tail current |
| Positive VF tempco | Enables natural current balancing in paralleled devices without external ballasting resistors |
| High surge rating | IFSM = 28 A (8.3 ms half-sine) supports inrush and fault-current handling in UPS and motor drives |
| Green packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); RoHS 3 compliant |
Applications
| Power Factor Correction | Industrial Motor Drives |
|---|---|
Use Scenario: Boost rectifier in 3 kW single-phase AC-DC front-end with 100 kHz switching frequency. IC Role / Device Role / Timing Role: High-voltage, high-speed output rectifier replacing Si FRD to reduce losses and improve THD. Use Value: Cuts conduction loss by 35% vs. Si FRD and eliminates Qrr-related EMI, easing filter design. | Use Scenario: Freewheel diode across IGBTs in 7.5 kW VFD output stage operating at 15 kHz PWM. IC Role / Device Role / Timing Role: Snubberless flyback path for inductive load current during IGBT turn-off.

IC Role / Device Role / Timing Role: Bidirectional blocking diode in double-conversion topology ensuring clean DC bus isolation. Use Value: Maintains <2 µA leakage at 175°C ambient, preventing battery drain during extended hold-up mode. | Use Scenario: Secondary-side synchronous rectifier replacement in 12 V/30 A telecom PSU with LLC resonant topology. IC Role / Device Role / Timing Role: Low-VF freewheeling element minimizing conduction loss at light-to-full load. Use Value: Delivers 0.8% higher full-load efficiency than 650 V Si Schottky due to lower VF tempco stability. |
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 |
|---|---|---|---|
| DSC04A065FP | Direct successor: improved VF (1.53 V max @ 4 A, 25°C) and lower RθJC (6.5 °C/W); same ITO220AC package | Drop-in replacement with enhanced efficiency in new designs; identical footprint and pinout | Select for new designs requiring highest efficiency and lowest thermal resistance |
| STPSC4H065D | 4 A, 650 V SiC Schottky; VF = 1.7 V max @ 4 A, 25°C; RθJC = 8.5 °C/W; TO-220AC package | Same electrical specs but higher thermal resistance; requires larger heatsink area | Use when STMicroelectronics supply chain alignment is required; verify mechanical fit of TO-220AC vs. ITO220AC |
Compared with DSC04065FP, the DSC04A065FP offers measurable efficiency gain (≈0.15 V lower VF) and thermal margin, while STPSC4H065D provides second-source availability at minor thermal penalty-both retain SiC benefits but differ in manufacturability and thermal integration.

FAQ
Is DSC04065FP recommended for new designs?
No. Diodes Incorporated explicitly states "DSC04065FP IS NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE DSC04A065FP." The newer variant improves forward voltage and thermal resistance while maintaining pin compatibility and ITO220AC packaging-making it the preferred choice for all new schematics and layouts.
What is the maximum allowable case temperature for continuous operation?
The DSC04065FP supports continuous operation up to +175°C case temperature, as confirmed by its TJ/TSTG rating (–55 to +175°C) and forward current derating curve. At this temperature, average forward current is approximately 2.2 A, based on linear derating from 4 A at 25°C per the datasheet Figure 1.
How does its reverse leakage compare to silicon diodes at elevated temperature?
At 650 V and +175°C, DSC04065FP exhibits ≤550 µA typical reverse leakage-still 10–100× lower than comparable 650 V silicon FRDs (>5 mA typical). This stability enables reliable blocking in high-temp environments like motor drive cabinets or solar inverters without thermal runaway risk.
Can the tab be electrically isolated from the cathode?
No. The metal tab is internally bonded to the cathode terminal (Lead 2) and shares the same electrical potential. Electrical isolation requires insulating hardware (e.g., shoulder washers, silicone pads) between tab and heatsink-failure to isolate may short the cathode to chassis ground in non-isolated topologies.
