Product details
Overview
DSC08C065D1-13 from Diodes Incorporated is a silicon carbide Schottky diode rated for 650 V peak repetitive reverse voltage, 8 A average rectified output current, and 1.7 V maximum forward voltage at +25°C. It serves as a high-efficiency rectifier or freewheeling diode in high-frequency, high-temperature power conversion stages including PFC circuits and industrial inverters.
For engineers reviewing the DSC08C065D1-13 datasheet, DSC08C065D1-13 pinout, DSC08C065D1-13 application, or DSC08C065D1-13 equivalent, key selection criteria include its low leakage (0.8 µA @ 650 V, +25°C), positive temperature coefficient of VF, and robust TO252 (Type WX) thermal performance up to +175°C junction temperature.
Technical Context
This SiC Schottky diode eliminates minority-carrier storage, enabling zero reverse recovery charge (Qrr ≈ 0) and near-ideal switching behavior. Its VF increases with temperature-ensuring inherent current sharing in parallel configurations and stable operation under thermal stress.
Designed for hard-switched topologies, it delivers 21 nC total capacitive charge (Qc) at 400 V reverse bias and exhibits 278 pF junction capacitance at 0.1 V, supporting high-frequency (>100 kHz) SMPS and inverter designs where di/dt-induced losses must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum blocking voltage before avalanche; enables use in 400 VAC input PFC and 600 V bus inverters. |
| IO (TC = +25°C) | 8 A - Continuous forward current rating at case temperature; derates to ~4.5 A at +125°C per Figure 1. |
| VF (MAX) | 1.7 V @ IF = 8 A, TJ = +25°C - Low conduction loss improves efficiency vs. Si PN diodes (~0.7–1.0 V higher VF). |
| IR (TYP) | 0.8 µA @ VR = 650 V, TJ = +25°C - Ultra-low leakage preserves system efficiency at high temperature and voltage. |
| RθJC | 3 °C/W - Thermal resistance from junction to case; supports direct heatsink mounting for high-power density layouts. |
| IFSM | 38 A @ 10 ms half-sine - Surge capability withstands inrush and fault currents in motor drives and UPS systems. |
| QC | 21 nC @ VR = 400 V, dI/dt = 200 A/µs - Capacitive charge determines turn-off energy loss in hard-switched converters. |
Pinout & Package
Package: TO252 (Type WX), surface-mount, 3-terminal plastic molded package with exposed copper drain pad for thermal and electrical connection. Dimensions per Diodes Package Outline Drawing: D = 6.10 mm, E = 6.60 mm, H = 10.10 mm, L = 1.50 mm, b3 = 5.33 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Forward current entry point | Connected to switching node (e.g., MOSFET drain); requires low-inductance layout to minimize voltage overshoot. |
| Cathode (Lead 3) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; large copper pour recommended for thermal dissipation. |
| Drain Pad (Exposed bottom) | Thermal and electrical cathode extension | Electrically tied to cathode; must be soldered to ≥1 in² 2 oz copper pad for RθJC = 3 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (Qrr) | Enables elimination of snubbers and reduces EMI in high-dV/dt applications like motor drives. |
| Positive VF temperature coefficient | Ensures natural current balancing in paralleled devices without external ballasting resistors. |
| 175°C maximum junction temperature | Supports operation in sealed enclosures or high-ambient environments without derating penalties. |

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 VRRM, same 8 A IO, VF = 1.8 V @ 8 A, RθJC = 2.5 °C/W | Higher voltage rating suits 800 VDC bus systems; tighter VF tolerance but lower surge rating (32 A IFSM) | Select when system DC bus exceeds 650 V or when lower thermal resistance is critical for compact heatsinking. |
| ON Semiconductor NSC08120D | 1200 V VRRM, VF = 1.75 V @ 8 A, IR = 1.2 µA @ 650 V, RθJC = 3.2 °C/W | Higher leakage at high temperature; slightly larger TO247-2L package limits board space efficiency | Prefer when AEC-Q101 qualification is required for automotive auxiliary inverters or onboard chargers. |
Compared with C4D08120A and NSC08120D, DSC08C065D1-13 offers optimal balance of 650 V rating, ultra-low leakage, and TO252 thermal performance for cost-sensitive industrial PFC and inverter designs where voltage margin is constrained.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DSC08C065D1-13 supports continuous operation up to +150°C case temperature, with derated average forward current of approximately 5.2 A per Figure 1. Operation beyond this requires thermal modeling using RθJC = 3 °C/W and verified heatsink interface resistance to ensure TJ ≤ +175°C.
Does this diode require a gate resistor or snubber network?
No. As a majority-carrier SiC Schottky device, it has no reverse recovery charge (Qrr ≈ 0) and does not generate voltage spikes during turn-off. Snubbers are unnecessary unless parasitic ringing occurs due to PCB layout inductance-addressed via proper grounding and minimized loop area instead of passive damping.
Can DSC08C065D1-13 be used in parallel configurations?
Yes-its positive temperature coefficient of forward voltage ensures inherent current sharing. Parallel operation requires matched layout symmetry, identical thermal paths, and shared cathode copper pour. Derate total current by 15% for two devices and 25% for three or more to account for thermal coupling effects.
Is this part qualified for automotive applications?
No-DSC08C065D1-13 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., DSC08C065D1Q) with PPAP documentation, IATF 16949 manufacturing, and extended reliability testing. For automotive use, contact Diodes' automotive sales team for qualified alternatives.
