Product details
Overview
DSC08A065D1 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 +25°C. It serves as a high-efficiency rectifier or freewheeling diode in power conversion stages requiring low switching loss and stable high-temperature operation, such as PFC circuits and industrial inverters.
For engineers reviewing the DSC08A065D1 datasheet, DSC08A065D1 pinout, DSC08A065D1 application, or DSC08A065D1 equivalent, key selection criteria include its 1.5 µA typical reverse leakage at 650 V/+25°C, 3 °C/W junction-to-case thermal resistance, TO252 (Type WX) package mounting compatibility, and verified performance up to +175°C junction temperature.
Technical Context
This SiC Schottky diode eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and eliminating associated switching losses. Its positive temperature coefficient on VF ensures inherent current-sharing stability in parallel configurations.
Designed for hard-switched topologies, it delivers 19 nC total capacitive charge (Qc) at 400 V reverse bias and exhibits 348 pF junction capacitance at 0.1 V - critical parameters for EMI control and snubber design in high-frequency SMPS and motor drive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Withstands DC blocking and transient overvoltage up to 650 V without breakdown. |
| IO | 8 A - Continuous average forward current capability at TC = +25°C with proper heatsinking. |
| VF (max) | 1.5 V @ IF = 8 A, TJ = +25°C - Low conduction loss enables >98% efficiency in high-current rectification. |
| IR (typ) | 1.5 µA @ VR = 650 V, TJ = +25°C - Ultra-low leakage preserves system efficiency and thermal margin. |
| RθJC | 3 °C/W - Enables direct thermal path to copper heatsink for compact thermal design in space-constrained inverters. |
| IFSM | 47 A (10 ms half-sine) - Supports surge handling during startup or fault conditions in UPS and motor drives. |
| TJ Range | –55°C to +175°C - Rated for under-hood automotive auxiliary supplies and industrial ambient environments. |

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 C4D08120A | 1200 V rating, 8 A IO, higher VF (1.8 V typ), TO247-2L package | Targeted at 1200 V systems (e.g., EV chargers); requires larger footprint and different thermal interface | Select when system bus voltage exceeds 800 V DC or when TO247 mechanical robustness is required. |
| ROHM SCT08H120A | 1200 V rating, 8 A IO, VF = 1.55 V max, same TO252-2L package | Higher VRRM enables use in 1000 V PV string inverters; identical mounting but derated for 650 V designs | Choose for cross-supply flexibility in multi-platform designs where 1200 V headroom is needed. |
Compared with C4D08120A and SCT08H120A, DSC08A065D1 offers optimal cost-performance balance for 650 V systems, with lower VF and smaller TO252 footprint - reducing PCB area and thermal interface complexity without sacrificing reliability.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device supports continuous operation up to +150°C case temperature, as confirmed by its derating curve (Figure 1). At TC = +150°C, IO is reduced to 4.5 A to maintain TJ ≤ +175°C with RθJC = 3 °C/W and 1.5 W dissipation limit.
Does DSC08A065D1 require a gate resistor or snubber network?
No - as a unipolar Schottky diode, it has no gate terminal and exhibits no reverse recovery. A snubber is optional and only needed if parasitic ringing occurs due to layout inductance; typical designs omit it due to low Qc (19 nC) and absence of dI/dt-induced voltage spikes.
Can this diode be used in parallel configurations?
Yes - its positive temperature coefficient on VF enables natural current sharing. Parallel operation requires matched trace lengths, symmetric thermal coupling to a common heatsink, and verification that total IR remains within system leakage budget at worst-case TJ = +175°C (230 µA max per device).
Is DSC08A065D1 qualified for automotive applications?
No - it is not AEC-Q101 qualified. While rated for –55°C to +175°C operation, it lacks PPAP documentation, change control, and IATF 16949 manufacturing certification required for automotive use. Diodes offers AEC-Q101 variants under separate part numbers.
