Product details
Overview
STPSC40065CW from STMicroelectronics is a 650 V, dual-die silicon carbide Schottky power diode in TO-247 package, rated for 2 × 20 A average forward current per diode and 175 °C maximum junction temperature. It delivers zero reverse recovery charge, temperature-independent switching, and low 1.30 V typical forward voltage at 20 A and 25 °C. Designed specifically for high-efficiency PFC stages in industrial AC-DC supplies and solar inverters.
For engineers reviewing the STPSC40065CW datasheet, STPSC40065CW pinout, STPSC40065CW application, or STPSC40065CW equivalent, key selection criteria include its dual-diode configuration, 650 V VRRM, 0.90 °C/W thermal resistance per diode, negligible turn-off ringing, and ECOPACK®2-compliant TO-247 packaging for high-reliability power conversion.
Technical Context
This device integrates two independent SiC Schottky diodes in a single TO-247 package, each with identical 650 V blocking capability and 20 A average forward current rating at Tc = 140 °C. Its wide-bandgap silicon carbide substrate enables stable operation up to 175 °C junction temperature without reverse recovery tail current or thermal runaway risk under defined (dPtot/dTj) conditions.
The diode exhibits minimal capacitive turn-off behavior: total junction capacitance is 1250 pF at 0 V and drops to 100 pF at 400 V, while total capacitive charge Qcj is 62 nC at 400 V. These characteristics directly support high-frequency, soft-switched PFC topologies such as totem-pole and interleaved boost converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 V AC input PFC stages with sufficient margin against line surges and transients. |
| IF(AV) | 2 × 20 A - Dual-diode structure supports parallel-phase or interleaved PFC designs without external paralleling. |
| VF (typ.) | 1.30 V @ 20 A, 25 °C - Reduces conduction loss in high-current PFC legs; increases efficiency over silicon alternatives. |
| Rth(j-c) | 0.90 °C/W per diode - Enables compact heatsink design with predictable thermal rise under continuous 20 A DC load per die. |
| Tj(max) | 175 °C - Allows sustained operation in enclosed industrial environments without derating below full current rating. |
| Qcj | 62 nC @ 400 V - Low stored capacitive charge minimizes switching loss and EMI during hard-commutation events. |
| Cj | 100 pF @ 400 V - Supports >100 kHz PFC switching frequencies with controlled dv/dt and reduced gate drive stress on companion MOSFETs. |
Pinout & Package
STPSC40065CW uses a standard 3-pin TO-247 package with dual-anode/dual-cathode internal configuration. Pins are arranged linearly: Pin 1 (A1) = Anode 1, Pin 2 (K) = Common Cathode, Pin 3 (A2) = Anode 2. The package features isolated mounting hole, UL 94 V0 epoxy, and 0.8 N·m recommended torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Connects to first switch node (e.g., phase leg of interleaved PFC); electrically isolated from A2. |
| K | Common Cathode | Shared output node for both diodes; ties to PFC output bus or boost inductor return path. |
| A2 | Anode of Diode 2 | Connects to second switch node; enables symmetrical layout and balanced thermal distribution across die pair. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge | Eliminates reverse recovery losses and associated EMI in hard-switched PFC, enabling >99% efficiency at 2 kW. |
| Switching behavior independent of temperature | Ensures consistent timing and loss profile across -40 °C to +175 °C ambient, critical for outdoor solar inverters. |
| Dedicated to PFC applications | Optimized doping and geometry reduce Qcj and Cj trade-offs specifically for boost/totem-pole rectification duty cycles. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements without compromising thermal or electrical performance. |

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 |
|---|---|---|---|
| C3D06060A | 650 V, 6 A single-diode TO-247; lower current rating, higher VF (1.5 V typ.) | Requires paralleling for ≥20 A designs; less suitable for space-constrained PFC modules. | Select when thermal budget allows higher VF or when single-diode isolation is preferred. |
| SS12065B | 650 V, 20 A single-diode TO-220AC; no dual-die integration, Rth(j-c) = 1.5 °C/W | Limited to single-phase PFC; requires larger heatsink area and additional mounting hardware. | Select for cost-sensitive, lower-power (<1.5 kW) applications where board space permits discrete layout. |
Compared with C3D06060A and SS12065B, STPSC40065CW uniquely combines dual-diode integration, 20 A per diode rating, and 0.90 °C/W thermal resistance-enabling compact, high-power-density PFC designs without paralleling or thermal compromise.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device supports continuous operation at Tc = 140 °C per diode for 20 A average forward current, based on maximum junction-to-case thermal resistance of 0.90 °C/W and 175 °C absolute maximum junction temperature. Derating is required above this case temperature to maintain safe Tj limits.
Can STPSC40065CW be used in a single-phase boost PFC instead of an interleaved design?
Yes - the dual-diode configuration can be used in single-phase boost PFC by connecting both anodes together and using the common cathode as the output. This provides redundancy and thermal spreading but does not increase current rating beyond 20 A per diode unless externally paralleled.
Is the TO-247 package electrically isolated between pins?
No - the TO-247 metal tab (pin 2, K) is electrically connected to the common cathode and is not insulated. Electrical isolation must be implemented externally via insulating washers or thermal pads if mounting to a grounded heatsink.
How does the 62 nC capacitive charge affect EMI in high-frequency PFC designs?
The 62 nC Qcj at 400 V contributes directly to high-frequency dv/dt-induced displacement current during turn-off. However, because it lacks reverse recovery current, this charge discharges predictably through the switching loop, enabling precise EMI filter sizing and reducing broadband noise peaks above 30 MHz compared to silicon diodes.
