Product details
Overview
DSC06A065FP from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 6 A average forward current, and 1.5 V maximum forward voltage at +25°C, with typical reverse leakage of 0.7 µA at 650 V and +25°C. It serves as a high-efficiency rectifier or freewheeling diode in power factor correction circuits, industrial motor drives, and SMPS topologies operating up to +175°C junction temperature.
For engineers reviewing the DSC06A065FP datasheet, DSC06A065FP pinout, DSC06A065FP application, or DSC06A065FP equivalent, key selection criteria include its low conduction loss (VF ≤ 1.64 V @ 6 A, +175°C), fast reverse recovery (no minority carrier storage), stable high-temperature leakage performance, and ITO220AC package thermal resistance of 5 °C/W (junction-to-case).
Technical Context
This SiC Schottky diode replaces silicon PN rectifiers in high-frequency, high-efficiency AC/DC and DC/DC conversion stages. Its unipolar conduction mechanism eliminates reverse recovery charge (Qrr ≈ 0), enabling operation at higher switching frequencies without associated switching losses.
Designed for continuous operation up to +175°C, it exhibits a positive temperature coefficient on forward voltage-ensuring inherent current sharing in parallel configurations-and maintains <200 µA leakage at 650 V and +175°C per datasheet characterization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - blocks full-line transients in 400 V DC bus systems without derating |
| IO | 6 A - continuous rectification capability at TC = +25°C, derates to ~3.5 A at TC = +100°C |
| VF (Max) | 1.5 V @ 6 A, +25°C - reduces conduction loss vs. Si diodes by ~40% at same current |
| IR (Typ) | 0.7 µA @ 650 V, +25°C - enables low standby power in offline PSUs |
| RθJC | 5 °C/W - allows direct mounting to heatsink for efficient thermal management |
| QC | 16 nC @ 400 V, +25°C - quantifies capacitive charge driving MOSFET gate during turn-off |
| TJ Range | –55°C to +175°C - supports under-hood automotive and industrial ambient environments |
Pinout & Package
Package: ITO220AC (Type WX-NC), molded plastic with matte tin-plated copper leadframe, UL 94V-0 rated, weight 1.497 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Current entry point | Electrically connected to metal tab; must be isolated from heatsink unless circuit ground reference |
| Cathode (Lead 1) | Current exit point | Single lead extending from package body; soldered to PCB trace or busbar |
Key Features
| Feature | Design Value |
|---|---|
| Low conduction & switching loss | Zero Qrr, VF ≤ 1.64 V @ 6 A, +175°C - enables >98% efficiency in 100 kHz+ PFC stages |
| High-temperature stability | Leakage remains <200 µA @ 650 V, +175°C - avoids thermal runaway in compact enclosures |
| Positive VF temperature coefficient | VF increases with temperature - enables natural current balancing in paralleled devices |
| Fast reverse recovery | No minority carrier storage - eliminates snubber requirements in hard-switched topologies |
| Robust surge capability | IFSM = 38 A (10 ms half-sine) - withstands inrush and fault currents 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 |
|---|---|---|---|
| STPSC6H065D | Same 650 V/6 A rating; RθJC = 4.5 °C/W; VF = 1.55 V @ 6 A, +25°C | Slightly lower thermal resistance but higher VF at elevated temperature | Prefer when heatsink interface area is constrained but thermal margin is available |
| WOLFSPEED C4D06120A | 1200 V rating; 6 A; VF = 1.8 V @ 6 A, +25°C; RθJC = 6.5 °C/W | Higher voltage grade with trade-off in conduction loss and thermal performance | Select only if system requires 1200 V blocking or future-proofing against voltage surges |
Compared with STPSC6H065D and C4D06120A, DSC06A065FP offers the lowest VF at high temperature and best thermal resistance among 650 V-class 6 A SiC diodes, making it optimal for space-constrained, high-efficiency PFC and inverter designs where thermal headroom is limited.

FAQ
Is DSC06A065FP suitable for automotive applications?
No-DSC06A065FP is not AEC-Q101 qualified. While it operates from –55°C to +175°C, Diodes Incorporated explicitly states that automotive-grade variants require separate qualification, PPAP capability, and IATF 16949 manufacturing. This part is intended for industrial and commercial power systems only.
What is the recommended minimum creepage distance for ITO220AC mounting?
Per Diodes' mechanical drawings and UL 94V-0 mold compound, the ITO220AC package requires ≥4.5 mm creepage between anode (tab) and cathode (lead) at 650 V working voltage. PCB layout must maintain this clearance on both surface and inner layers, especially under conformal coating.
Can DSC06A065FP be paralleled for higher current handling?
Yes-its positive temperature coefficient on forward voltage enables stable current sharing. Parallel operation requires matched layout impedance, identical thermal mounting, and individual gate-drive isolation if used in synchronous rectifier configurations. Derate total current by 15% for two devices.
Does DSC06A065FP require a snubber circuit in hard-switched topologies?
No-unlike silicon PN diodes, this SiC Schottky diode has negligible reverse recovery charge (Qrr ≈ 0), eliminating voltage spikes and ringing during turn-off. Snubbers are unnecessary unless parasitic layout inductance exceeds 20 nH in high-dI/dt (>100 A/µs) applications.
