Product details
Overview
STPSC2006CW from STMicroelectronics is a 600 V, 20 A (per device) silicon carbide Schottky power diode in TO-247 package, featuring negligible reverse recovery, temperature-independent switching, and 12 nC typical capacitive charge. It serves as a high-efficiency PFC boost diode in hard-switching AC-DC front-ends for industrial SMPS and server power supplies.
For engineers reviewing the STPSC2006CW datasheet, STPSC2006CW pinout, STPSC2006CW application, or STPSC2006CW equivalent, key selection criteria include its 600 V VRRM, 175 °C max junction temperature, 1.4–2.1 V forward voltage range, zero-recovery behavior, and thermal resistance of 1.2 °C/W (total).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency PFC stages by eliminating reverse recovery current and associated switching losses. Its wide-bandgap construction enables stable operation up to 175 °C with minimal drift in VF and IR.
The device integrates two parallel 10 A diodes in a single TO-247 package, delivering 20 A average forward current at Tc = 100 °C with δ = 0.5. Its 650 pF junction capacitance at 0 V and 12 nC QC support clean turn-off under dIF/dt = −200 A/µs conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports universal input (85–265 VAC) PFC designs with margin against line surges |
| IF(AV) | 20 A (per device) - enables high-power 3–5 kW PFC stages without paralleling discrete diodes |
| Tj(max) | 175 °C - allows sustained operation in thermally constrained enclosures without derating |
| QC | 12 nC (typ.) - reduces turn-off energy loss and EMI generation in 65–100 kHz boost converters |
| Rth(j-c) | 1.2 °C/W (total) - supports direct heatsink mounting with predictable thermal rise under full load |
| VF | 1.4–2.1 V (at 10 A, 25–150 °C) - delivers lower conduction loss than Si FRDs while maintaining soft switching |
| CJ | 650 pF (at 0 V, 25 °C) - minimizes capacitive displacement current during high-dv/dt transitions |
Pinout & Package
Package: TO-247 (3-pin, straight lead), epoxy body compliant with UL94 V0; recommended torque: 0.55–1.0 N·m; weight: 4.36 g; cooling method: convection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | First diode anode | Internally connected to one 10 A SiC die; used for dual-anode parallel configuration or independent channel routing |
| Anode 2 (A2) | Second diode anode | Connected to second 10 A SiC die; enables balanced current sharing when both anodes are tied externally |
| Cathode (K) | Common cathode | Shared cathode terminal for both internal diodes; simplifies PCB layout in single-output PFC topologies |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Eliminates switching tail current and associated snubber losses in continuous conduction mode PFC |
| Temperature-stable switching | VF and QC vary <±10% from 25 °C to 150 °C, enabling consistent timing across thermal cycles |
| Dual-diode integration | Two 10 A SiC dies in one TO-247 reduce footprint vs. discrete dual-diode solutions and improve thermal coupling |
| High surge capability | 160 A non-repetitive peak forward current (10 µs square wave) supports inrush and fault transient handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D02060E (Wolfspeed) | Single 10 A diode, same 600 V rating, 13 nC QC, TO-247-2L package | Requires external paralleling for 20 A operation; lacks dual-anode convenience | Preferred where board space allows separate thermal paths or where legacy layout uses 2-pin TO-247 footprints |
| SS1206 (Rohm) | 650 V rating, 20 A avg, but 1.75 V VF (typ.) at 10 A/25 °C and 18 nC QC | Higher conduction and switching loss; suitable only for lower-frequency (<50 kHz) PFC | Consider only if cost sensitivity outweighs efficiency targets and thermal constraints permit higher VF penalty |
Compared with C3D02060E and SS1206, STPSC2006CW uniquely combines dual 10 A dies in one TO-247, lowest QC, and tightest VF spread-making it optimal for compact, high-frequency, high-reliability PFC designs where layout simplicity and thermal predictability are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPSC2006CW supports 20 A average forward current at Tc = 100 °C with duty cycle δ = 0.5. At Tc = 115 °C, rated current drops to 10 A per diode. Exceeding 115 °C case temperature requires derating per Figure 3 in the datasheet; sustained operation above 125 °C case risks accelerated parameter drift.
Can STPSC2006CW be used in synchronous rectification topologies?
No. STPSC2006CW is a unidirectional Schottky diode with no gate control or reverse conduction capability. It is not designed for synchronous rectification, which requires actively controlled MOSFETs or integrated driver+MOSFET devices. Its role is strictly as a high-performance freewheeling/boost rectifier.
How does its thermal resistance compare between per-diode and total values?
Rth(j-c) is 2.0 °C/W per diode and 1.2 °C/W total (both diodes combined). This reflects shared thermal path through the common cathode slug and package base. The lower total value confirms effective thermal coupling-critical for accurate junction temperature estimation in dual-die operation.
Is the TO-247 footprint compatible with standard heatsink mounting hardware?
Yes. The TO-247 outline matches JEDEC MS-003 standards. Mounting hole diameter is 3.55–3.65 mm, and recommended torque is 0.55–1.0 N·m. Standard M3 screws and isolating washers (e.g., mica + silicone grease) are fully compatible for thermal interface assembly.
