Product details
Overview
DSC02120FP from Diodes Incorporated is a 1200 V, 2 A silicon carbide Schottky diode in ITO220AC (Type WX-NC) package, featuring 1.7 V max forward voltage at 2 A and 11.4 µA typical reverse leakage at 1200 V/25°C. It serves as a high-efficiency rectifier or freewheel diode in high-voltage power conversion stages including PFC circuits, industrial motor drives, and UPS systems.
For engineers reviewing the DSC02120FP datasheet, DSC02120FP pinout, DSC02120FP application, or DSC02120FP equivalent, key selection criteria include its 1200 V blocking capability, low conduction loss at elevated temperatures, fast reverse recovery (<30 ns), high surge current rating (24 A), and thermal resistance of 16 °C/W junction-to-case.
Technical Context
This SiC Schottky diode operates with zero minority-carrier injection, eliminating reverse recovery charge (Qrr ≈ 0) and enabling high-frequency switching with minimal switching loss. Its positive temperature coefficient on VF ensures inherent current sharing in parallel configurations.
Designed for operation up to +175°C junction temperature, it maintains stable reverse leakage (128 µA at 1200 V/175°C) and low capacitance (30 pF at 40 V), supporting efficient hard-switched and resonant topologies in industrial and renewable energy inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - supports DC-link voltages up to 800 V nominal in three-phase inverters with 50% safety margin |
| IO (avg) | 2 A - continuous conduction capability at TC ≤ 100°C per derating curve |
| VF (max) | 1.7 V @ 2 A, 25°C - reduces conduction loss to <3.4 W at rated current |
| IR (typ) | 11.4 µA @ 1200 V, 25°C - enables low standby power in high-voltage hold-up circuits |
| RθJC | 16 °C/W - allows 100°C temperature rise with 6.25 W dissipation on standard heatsink |
| IFSM | 24 A @ 10 ms half-sine - withstands inrush and fault currents in SMPS and motor drive outputs |
| QC | 10 nC @ 400 V, 25°C - minimizes turn-off loss in high-frequency ZVS/ZCS converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D02065E | 650 V VRRM, same 2 A IO, lower VF (1.5 V), higher IR (25 µA @ 650 V) | Not suitable for 1200 V DC-link; limited to 400–600 V systems | Select only when system voltage ≤ 600 V and lower conduction loss is prioritized over blocking capability |
| SDT20120V | 1200 V VRRM, 2 A IO, VF = 1.8 V (max), RθJC = 18 °C/W, no halogen-free certification | Higher thermal resistance requires larger heatsink; lacks RoHS 3 compliance documentation | Acceptable where extended temperature margin is not required and environmental compliance is secondary |
Compared with C3D02065E and SDT20120V, DSC02120FP uniquely balances 1200 V robustness, 16 °C/W thermal performance, and full RoHS 3/halogen-free compliance-making it optimal for industrial UPS and solar inverter designs requiring long-term reliability and regulatory alignment.

FAQ
Is DSC02120FP qualified for automotive applications?
No. DSC02120FP is not AEC-Q101 qualified and is not recommended for automotive use. Diodes offers separate AEC-Q101-qualified SiC diodes (e.g., DSC02120Q) with PPAP support and IATF 16949 manufacturing. This part is intended for industrial, computing, and renewable energy applications only.
What is the maximum allowable case temperature for continuous operation?
The DSC02120FP supports continuous operation up to +150°C case temperature, as shown in Figure 1's derating curve. At TC = 150°C, the average forward current is reduced to 1.2 A. Operation beyond this requires verification of junction temperature using RθJC = 16 °C/W and actual power dissipation.
Can DSC02120FP be used in parallel configurations?
Yes-its positive temperature coefficient on forward voltage enables natural current sharing. Parallel operation requires matched layout (equal trace inductance/resistance), shared heatsinking, and thermal coupling. Derate total current by 15% for two devices and 25% for three or more to ensure margin under mismatch conditions.
Does the ITO220AC package require thermal interface material?
Yes. The ITO220AC mounting tab must be attached to a heatsink using thermally conductive interface material (e.g., silicone grease or phase-change pad) to achieve the specified RθJC = 16 °C/W. Mechanical fastening alone yields >3× higher thermal resistance due to micro-air gaps at the interface.
