Product details
Overview
STPSC1006G-TR from STMicroelectronics is a 600 V, 10 A average forward current silicon carbide Schottky diode in D2PAK (TO-263) 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 power supplies and server PSUs.
For engineers reviewing the STPSC1006G-TR datasheet, STPSC1006G-TR pinout, STPSC1006G-TR application, or STPSC1006G-TR equivalent, key selection criteria include its 600 V VRRM, 175 °C max junction temperature, 2.1 V max forward voltage at 150 °C, 650 pF capacitance at 0 V, and thermal resistance of 2 °C/W - all critical for high-frequency, high-temperature PFC stage reliability.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in continuous conduction mode (CCM) PFC stages by eliminating reverse recovery losses and associated EMI. Its wide bandgap enables stable operation up to 175 °C with no recovery tail, enabling higher switching frequencies and reduced filter size.
The device exhibits minimal variation in forward voltage (1.4–2.1 V) and leakage current (150–1500 µA) across –40 to +175 °C, and its 12 nC QC at 400 V and 150 °C ensures low turn-off loss under dIF/dt = –200 A/µs conditions typical in 65–100 kHz PFC designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports universal input (85–265 VAC) PFC stages with 2× safety margin against line transients |
| IF(AV) | 10 A at Tc = 115 °C - delivers 500–600 W output power in thermally managed 1U server PSU designs |
| VF (max) | 2.1 V at IF = 10 A, Tj = 150 °C - limits conduction loss to ≤21 W in worst-case thermal condition |
| QC (typ) | 12 nC at VR = 400 V, dIF/dt = –200 A/µs - reduces turn-off energy loss below 2.4 µJ per switching cycle |
| Rth(j-c) | 2 °C/W - enables 150 °C junction operation with ≤75 °C case temperature under 10 A DC load |
| C (typ) | 650 pF at VR = 0 V - sets high-frequency impedance and influences snubber design in >65 kHz PFC circuits |
| Tj (max) | +175 °C - allows derating-free operation in sealed enclosures with limited airflow, common in telecom rectifiers |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated tab; thermally enhanced copper leadframe; RoHS-compliant, ECOPACK®-qualified; footprint compatible with standard D2PAK land pattern (9.35 mm × 10.40 mm body, 15.85 mm length).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Power input terminal (cathode-connected heatsink mounting surface) | Electrically connected to cathode; requires insulated thermal interface when mounted to grounded heatsink |
| Cathode (Pin 1) | Power output terminal | Soldered to PCB trace carrying switched PFC output; carries full load current and high dv/dt during turn-on |
| Source / NC | No connection | D2PAK variant has only two terminals - anode (tab) and cathode (pin); no third terminal present |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge | Eliminates recovery-related switching loss and EMI, enabling clean zero-current turn-off in CCM PFC |
| Temperature-stable switching | Forward voltage and leakage vary <±15% from 25 to 150 °C - simplifies thermal design and control loop compensation |
| High-temperature capability | Rated for continuous operation at 175 °C junction - supports compact, fanless power supply designs |
| Low capacitive charge | 12 nC QC minimizes stored energy dissipation during hard commutation, reducing MOSFET gate driver stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10060E-TR | Same 600 V/10 A rating; 1.7 V VF max at 150 °C; 13 nC QC; TO-263-2L package | Higher VF increases conduction loss by ~5% at 10 A; identical thermal resistance | Prefer when sourcing diversification is required and minor efficiency trade-off is acceptable |
| SS10P6 | Silicon-based ultrafast diode; 600 V/10 A; 3.2 V VF; 50 nC QRR; TO-220AC | Significant reverse recovery causes >3× switching loss and EMI; limited to ≤125 °C operation | Only suitable for cost-sensitive, low-frequency (<30 kHz), non-EMI-critical legacy designs |
Compared with C3D10060E-TR, STPSC1006G-TR offers lower VF and QC, improving efficiency in high-frequency PFC; versus SS10P6, it eliminates recovery loss entirely, enabling higher density and cooler-running systems despite higher unit cost.

FAQ
Is STPSC1006G-TR suitable for use in synchronous rectification topologies?
No - STPSC1006G-TR is a unidirectional Schottky diode with fixed anode/cathode polarity and no gate control. It cannot replace MOSFETs in synchronous rectification. It is designed exclusively for hard-switched or quasi-resonant boost rectification where passive conduction is required.
What is the maximum recommended PCB copper area for thermal relief on the D2PAK tab?
ST recommends ≥400 mm² of 2-oz copper connected to the tab via ≥4 thermal vias (0.4 mm diameter, filled) for optimal heat transfer. With this layout, Rth(j-a) drops to ~25 °C/W, allowing 10 A operation at ≤60 °C ambient with natural convection.
Does STPSC1006G-TR require a gate resistor or snubber network?
No gate resistor is needed since it is not a controlled device. A small RC snubber (e.g., 100 Ω + 100 pF) may be used across anode–cathode if parasitic ringing exceeds EMI limits, but it is often unnecessary due to inherently low QC and absence of reverse recovery.
Can STPSC1006G-TR be paralleled with another unit for higher current handling?
Yes - positive temperature coefficient of VF enables inherent current sharing. Use matched layout symmetry, identical trace lengths, and Kelvin sensing for each device. Derate total current by 15% to account for thermal coupling and manufacturing tolerances in parallel configurations.
