Diodes Incorporated DSC02120D1-13

Overview

DSC02120D1-13 from Diodes Incorporated is a 1200 V, 2 A silicon carbide Schottky diode in TO252-2 (Type WX) package, optimized for high-efficiency rectification in high-voltage power conversion. It delivers low forward voltage (1.7 V max at 2 A, 25°C), ultra-low reverse leakage (10.7 µA at 1200 V, 25°C), and fast recovery with 15 nC total capacitive charge-enabling use in PFC stages, industrial motor drives, and UPS inverters.

For engineers reviewing the DSC02120D1-13 datasheet, DSC02120D1-13 pinout, DSC02120D1-13 application, or DSC02120D1-13 equivalent, key selection criteria include its 1200 V blocking rating, thermal resistance (9 °C/W junction-to-case), positive temperature coefficient on VF, surge capability (24 A IFSM), and RoHS-compliant green packaging.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-temperature switching applications. Its zero reverse recovery charge eliminates switching losses associated with minority-carrier devices, while its 175°C maximum junction temperature supports operation in thermally constrained environments without derating.

The device exhibits a positive temperature coefficient of forward voltage-ensuring current sharing stability in parallel configurations-and maintains low leakage (<156 µA at 1200 V, 175°C), critical for reliability in industrial inverters and solar string converters where thermal runaway must be avoided.

Key Specifications

FAQ

Is DSC02120D1-13 recommended for new designs?

No-Diodes Incorporated explicitly states "DSC02120D1 IS NOT RECOMMENDED FOR NEW DESIGNS." This reflects planned obsolescence or migration to newer-generation SiC diodes. Engineers should contact Diodes or Aetrix for qualified replacements such as the DSC02120D2 or next-gen alternatives before initiating new schematics.

What is the maximum allowable case temperature for continuous operation?

The DSC02120D1-13 supports continuous operation up to +175°C junction temperature. With RθJC = 9 °C/W, sustained 2 A conduction requires case temperature ≤157°C to stay within thermal limits-verified via derating curve in DS44279. At 100°C case, it delivers full 2 A; at 150°C case, rated current drops to ~1.1 A.

Does this diode require a gate resistor or snubber network?

No-unlike silicon IGBTs or MOSFETs, the DSC02120D1-13 is an uncontrolled two-terminal device with no gate. As a SiC Schottky diode, it has no reverse recovery charge and therefore needs no snubber. Layout best practices focus on minimizing loop inductance between anode/cathode traces to suppress voltage overshoot during di/dt transitions.

How does the TO252-2 (Type WX) package differ from standard TO252-2?

The "Type WX" designation indicates Diodes' proprietary variant of TO252-2 with optimized internal die attach and leadframe geometry for enhanced thermal performance and mechanical robustness. Key differences include tighter dimensional tolerances (e.g., A2 = 0.97–1.17 mm), specific mold compound formulation for high-Tg stability, and matte tin plating optimized for Pb-free reflow-detailed in Diodes' package outline DS44279 Rev. 5.
