Product details
Overview
MSC030SDA120BCT from Microsemi is a 1200 V, 30 A silicon carbide (SiC) dual common-cathode Schottky barrier diode in a TO-247-3L package, designed for high-voltage PFC and inverter freewheeling applications with zero reverse recovery, low VF (1.5 V typ. @ 30 A, 25 °C), and low leakage (9 μA @ 1200 V, 175 °C).
For engineers reviewing the MSC030SDA120BCT datasheet, MSC030SDA120BCT pinout, MSC030SDA120BCT application, or MSC030SDA120BCT equivalent, this page delivers verified electrical specs, thermal resistance (0.4 °C/W typ.), junction capacitance (105–141 pF), avalanche energy rating (100 mJ), and real-world use context for industrial power conversion design.
Technical Context
The MSC030SDA120BCT integrates two independent SiC Schottky diodes sharing a common cathode terminal, enabling anti-parallel operation with IGBTs or MOSFETs in bridge legs. Its zero-recovery behavior eliminates switching tail current and associated losses.
Rated for 1200 V DC blocking and 30 A continuous forward current per leg at TC = 25 °C, it operates across –55 °C to +175 °C junction temperature with RθJC of 0.4 °C/W (typ.) and avalanche-rated energy of 100 mJ under defined test conditions (L = 0.22 mH, IL = 30 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max DC reverse voltage | 1200 V - supports primary-side rectification and clamp circuits in 800 V bus systems with margin |
| Forward voltage (VF) | 1.5 V (typ.) @ 30 A, 25 °C - reduces conduction loss vs. Si diodes by ~30% at same current |
| Reverse leakage current | 9 μA @ 1200 V, 175 °C - enables stable high-temp operation without thermal runaway |
| Junction-to-case thermal resistance | 0.4 °C/W (typ.) - allows >110 W dissipation at ΔT = 44 °C, supporting compact heatsink designs |
| Total capacitive charge (QC) | 130 nC @ VR = 600 V - minimizes turn-on loss in hard-switched topologies |
| Avalanche energy rating | 100 mJ (single pulse) - withstands inductive switching transients without failure |
| Junction capacitance (CJ) | 105 pF @ 800 V - lowers EMI generation during fast dv/dt transitions |
Pinout & Package
MSC030SDA120BCT uses a TO-247-3L package with three external terminals: Anode 1 (Terminal 1), Common Cathode (Terminal 2), and Anode 2 (Terminal 3). The metal tab is electrically isolated and serves as mechanical mounting surface only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode 1 | First diode anode; connects to high-side switch node in half-bridge freewheeling path |
| Terminal 2 | Common Cathode | Shared cathode node for both diodes; ties to DC bus midpoint or low-side switch source |
| Terminal 3 | Anode 2 | Second diode anode; used for complementary leg or snubber path in dual-phase designs |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Eliminates reverse recovery charge (Qrr = 0), removing switching loss and EMI spikes in hard-switched converters |
| Low forward voltage | 1.5 V typical at 30 A/25 °C enables >98% efficiency in 3.3 kW PFC stages at full load |
| Avalanche energy rated | 100 mJ single-pulse rating ensures robustness against inductive kickback in motor drive H-bridges |
| High-temperature operation | Rated to +175 °C junction enables derating-free use in sealed industrial enclosures with ambient up to +85 °C |
| RoHS compliant | Fully compliant with EU Directive 2011/65/EU; lead-free matte tin-plated leads and halogen-free molding compound |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D03065E-TR | 650 V rating, 30 A, TO-247-2L; lower VRRM but higher IF at elevated TC | Optimized for 400 V bus systems (e.g., EV chargers); not suitable for 800 V PFC front-ends | Select when system DC bus ≤650 V and thermal management prioritizes higher continuous current over voltage margin |
| STPSC30H12D | 1200 V, 30 A, TO-247-2L; single-diode; no common-cathode dual configuration | Requires two devices for dual-leg use; lacks integrated dual-anode topology for compact half-bridge layout | Choose when discrete placement flexibility outweighs PCB area savings from dual-in-one packaging |
Compared with C3D03065E-TR and STPSC30H12D, the MSC030SDA120BCT uniquely delivers 1200 V blocking in a dual-common-cathode TO-247-3L package-enabling single-component replacement of two discrete diodes in PFC and inverter half-bridges while preserving layout compactness and thermal coupling.

FAQ
What is the maximum continuous forward current rating for MSC030SDA120BCT?
The MSC030SDA120BCT is rated for 30 A DC forward current per diode leg at case temperature TC = 25 °C. Derating applies above that temperature: 29 A at TC = 135 °C and 24 A at TC = 145 °C. These values are specified in the Absolute Maximum Ratings table and reflect safe steady-state operation with appropriate heatsinking.
Does MSC030SDA120BCT have a common cathode configuration?
Yes, the MSC030SDA120BCT features a dual common-cathode configuration with two anodes (Terminals 1 and 3) and one shared cathode (Terminal 2). This architecture supports anti-parallel pairing with switches in half-bridge topologies and simplifies PCB layout for PFC and inverter applications.
What is the junction-to-case thermal resistance (RθJC) of MSC030SDA120BCT?
The MSC030SDA120BCT has a typical junction-to-case thermal resistance of 0.4 °C/W and a maximum of 0.58 °C/W, measured under standard mounting conditions. This low value enables efficient heat transfer to external heatsinks and supports high-power density designs in constrained thermal environments.
Is MSC030SDA120BCT avalanche-rated, and what test conditions apply?
Yes, the MSC030SDA120BCT is avalanche-energy rated at 100 mJ per pulse, tested with starting junction temperature TJ = 25 °C, inductance L = 0.22 mH, and peak inductor current IL = 30 A. This rating confirms ruggedness against inductive switching transients in motor drive and converter applications.
What package type does MSC030SDA120BCT use, and how many pins does it have?
The MSC030SDA120BCT uses a TO-247-3L package with three external terminals: Terminal 1 (Anode 1), Terminal 2 (Common Cathode), and Terminal 3 (Anode 2). The metal tab is electrically isolated and intended solely for mechanical mounting and thermal conduction.
