Product details
Overview
DSC04A065D1 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage and 4 A average rectified output current, with a maximum forward voltage of 1.66 V at 4 A and +175°C. It delivers low conduction loss, fast reverse recovery, and stable reverse leakage up to 175°C, making it suitable for high-efficiency power conversion in industrial motor drivers and UPS systems.
For engineers reviewing the DSC04A065D1 datasheet, DSC04A065D1 pinout, DSC04A065D1 application, or DSC04A065D1 equivalent, key selection criteria include its 7 °C/W junction-to-case thermal resistance, 12 nC total capacitive charge at 400 V, 29 A non-repetitive surge rating, TO252 (Type WX) package mounting requirements, and temperature-stable VF with positive TC.
Technical Context
This SiC Schottky diode operates without minority-carrier storage, enabling zero reverse recovery charge and eliminating switching tail current. Its unipolar conduction mechanism ensures consistent performance across -55°C to +175°C operating range, with leakage current remaining below 124 µA at 650 V and +175°C.
The device uses a planar junction structure optimized for high-voltage blocking and low capacitance-typical junction capacitance is 125 pF at 1 V reverse bias-and integrates a robust copper leadframe with matte tin terminations for reliable solderability and thermal transfer in high-power PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports DC bus voltages up to 400–450 V in three-phase PFC and inverter designs |
| IO (TC = +25°C) | 4 A - continuous conduction capability with derating to ~2.2 A at TC = +100°C per Figure 1 |
| VF (max) | 1.66 V @ 4 A, +175°C - enables lower conduction loss than Si counterparts at elevated temperatures |
| IR (typ) | 1.6 µA @ 650 V, +25°C - ultra-low leakage critical for high-impedance blocking applications |
| RθJC | 7 °C/W - allows direct heatsink mounting on 40 mm × 40 mm copper pad for thermal management |
| QC | 12 nC @ 400 V - reduces switching loss in hard-switched SMPS and inverter freewheel paths |
| IFSM | 29 A (10 ms half-sine) - withstands startup surges and fault transients in motor drive DC links |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Wolfspeed C4D04065A | Same 650 V / 4 A rating; VF = 1.7 V max @ 4 A, +175°C; RθJC = 6.5 °C/W | Slightly higher VF increases conduction loss in high-duty-cycle PFC; tighter thermal resistance aids compact heatsinking | Prefer when board space is constrained and thermal interface resistance can be minimized |
| ROHM SCS304AG | 650 V / 4 A; VF = 1.55 V max @ 4 A, +175°C; RθJC = 8.5 °C/W; TO263 package | Higher thermal resistance requires larger copper area; TO263 offers better mechanical retention but larger footprint | Choose when mechanical robustness under vibration is prioritized over minimal thermal resistance |
Compared with C4D04065A and SCS304AG, the DSC04A065D1 provides the lowest VF at high temperature among TO252-packaged 4 A SiC diodes, with optimal balance of thermal performance, footprint, and leakage stability for cost-sensitive industrial power supplies.

FAQ
What is the recommended PCB layout for thermal management of DSC04A065D1?
The exposed cathode pad must be soldered to a minimum 1 in² (645 mm²) copper area with 2 oz thickness, using at least four thermal vias (0.3 mm diameter, spaced ≤2 mm apart) connecting to inner or backside ground planes. Avoid solder mask over the pad to maximize thermal transfer and ensure mechanical reliability under thermal cycling.
Does DSC04A065D1 require a gate resistor or snubber network?
No-this is a passive Schottky diode with no gate terminal. Unlike MOSFETs or IGBTs, it does not require gate drive components. However, a small RC snubber (e.g., 100 Ω + 100 pF) across anode–cathode may be used in high-di/dt inverter legs to suppress voltage ringing caused by stray inductance and junction capacitance interaction.
Can DSC04A065D1 be paralleled for higher current handling?
Yes-its positive temperature coefficient of forward voltage enables natural current sharing. Use matched trace lengths, identical thermal mounting conditions, and symmetric layout to ensure balanced current distribution. Derate total current by 15% versus sum of individual ratings to account for layout-induced imbalances and thermal coupling.
Is DSC04A065D1 qualified for automotive applications?
No-DSC04A065D1 is not AEC-Q101 qualified. While it operates reliably from -55°C to +175°C, Diodes Incorporated explicitly states that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing, and AEC-Q101 testing); this part is intended for industrial, computing, and telecom power systems.
