Product details
Overview
STPSC2H065B-TR from STMicroelectronics is a 650 V, 2 A silicon carbide (SiC) Schottky power diode in DPAK package, designed for high-efficiency PFC and hard-switching DC/DC converters. It delivers zero reverse recovery charge, temperature-independent switching, 1.38 V typical forward voltage at 25 °C, 175 °C max junction temperature, and 7.9 nC capacitive charge at 400 V - enabling reduced EMI and conduction losses in LLC and boost topologies.
For engineers reviewing the STPSC2H065B-TR datasheet, STPSC2H065B-TR pinout, STPSC2H065B-TR application in PFC stages or LLC resonant converters, or STPSC2H065B-TR equivalent SiC diodes, this page provides verified electrical parameters, thermal behavior, package dimensions, and real-world design implications - not generic diode theory.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-temperature power conversion. Its wide-bandgap construction eliminates minority-carrier storage, resulting in no reverse recovery current and negligible ringing during turn-off - critical for maintaining ZVS in resonant topologies.
The device operates up to 175 °C junction temperature with stable VF and IR characteristics across temperature, supported by a 2.50 °C/W typical junction-to-case thermal resistance. Its 135 pF junction capacitance at 0 V and 14 pF at 400 V enables predictable soft-switching behavior under varying bus voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports 400 V DC bus with 1.6× safety margin in industrial PFC designs |
| IF(AV) | 2 A at Tc = 160 °C - continuous conduction mode operation with minimal heatsink requirement |
| VF(typ.) | 1.38 V at IF = 2 A, Tj = 25 °C - reduces conduction loss vs. Si FRD (typically >2.0 V) |
| Qcj | 7.9 nC at VR = 400 V - low capacitive charge minimizes turn-off energy and EMI in MHz-range switching |
| Rth(j-c) | 2.50 °C/W typ. - enables direct mounting to PCB copper pour or small heatsink for thermal management |
| IR | 20 µA at VR = VRRM, Tj = 25 °C - low leakage preserves efficiency in standby and light-load conditions |
| Cj | 135 pF at VR = 0 V, 1 MHz - defines snubber sizing and resonant tank interaction in LLC designs |
Pinout & Package
The STPSC2H065B-TR uses a surface-mount DPAK (TO-252) package with three terminals: anode, cathode, and exposed drain pad (electrically connected to cathode). The package features UL94 V0 epoxy, 0.35 g mass, and optimized thermal path via the large copper tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to input side of boost/PFC stage; must handle 20 A surge (10 ms sine) |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Electrically tied to exposed tab; requires low-impedance PCB copper pour for thermal dissipation |
| Exposed Tab | Cathode connection & thermal interface | Not isolated - must be routed to cathode net; primary heat transfer path to PCB or heatsink |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge | Eliminates switching loss spikes and EMI generation in hard-switched PFC and boost circuits |
| Temperature-independent switching | VF and Qcj remain stable from −40 °C to +175 °C - simplifies thermal derating in sealed enclosures |
| High forward surge capability | 20 A non-repetitive surge (10 ms sine, Tc = 25 °C) supports inrush and transient overload without failure |
| ECOPACK2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements for industrial and automotive-grade production |
| Power-efficient conduction | Conduction loss modeled as P = 1.001 × IF(AV) + 0.474 × IF²(RMS) - enables accurate thermal simulation |
Applications
| Server Power Supply PFC Stage | Industrial DC/DC Converter |
|---|---|
Use Scenario: Active PFC front-end in 1–3 kW telecom/server PSUs operating at 100–300 kHz. IC Role / Device Role / Timing Role: Boost diode handling continuous 2 A average current and 20 A surge during line transients. Use Value: Zero reverse recovery eliminates shoot-through risk in interleaved PFC and reduces MOSFET gate drive stress. | Use Scenario: Output rectification in isolated 48 V–12 V DC/DC modules for factory automation controllers. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in asymmetrical half-bridge topology with 200 kHz switching. Use Value: Stable 1.38 V VF across temperature avoids output voltage droop during thermal cycling in unventilated cabinets. |
| LLC Resonant Converter | Solar Microinverter Boost Stage |
Use Scenario: Secondary-side rectification in high-efficiency LLC resonant converters for LED drivers and UPS systems. IC Role / Device Role / Timing Role: High-frequency freewheeling diode with <10 ns turn-off transition and no tail current. Use Value: Negligible ringing allows tighter layout, smaller EMI filters, and higher power density without compromising EMC compliance. | Use Scenario: DC boost stage in single-phase microinverters interfacing 30–60 V PV strings to 400 V grid interface. IC Role / Device Role / Timing Role: 650 V-rated boost diode operating at 50–100 kHz with ambient temperatures up to 85 °C. Use Value: 175 °C max junction rating enables full 2 A output even at elevated ambient, improving energy harvest in hot rooftop installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D02065E-TR | Same 650 V/2 A rating; 1.55 V VF (typ.) at 2 A, 25 °C; 10.5 nC Qcj at 400 V | Higher VF increases conduction loss by ~12% at full load; higher Qcj raises turn-off EMI risk in >200 kHz designs | Prefer STPSC2H065B-TR where low EMI and thermal stability are prioritized over cost-sensitive volume production |
| SS12065A-TR | 650 V/2 A; 1.45 V VF (typ.) at 2 A, 25 °C; 125 pF Cj at 0 V; Rth(j-c) = 3.0 °C/W | Higher thermal resistance limits power density; higher Cj affects resonant timing accuracy in precision LLC control | Acceptable for lower-frequency (<100 kHz), lower-power (<1 kW) applications where board space is less constrained |
Compared with C3D02065E-TR and SS12065A-TR, the STPSC2H065B-TR offers the lowest combined conduction and switching loss profile due to its 1.38 V VF and 7.9 nC Qcj - making it optimal for high-frequency, thermally constrained PFC and LLC designs requiring minimal EMI filtering.

FAQ
Is STPSC2H065B-TR pin-compatible with standard silicon FRDs in DPAK?
No - while the DPAK footprint matches, the STPSC2H065B-TR has no reverse recovery and lower VF, requiring re-optimization of snubber networks and gate drive timing. Its cathode-tab connection also mandates direct thermal coupling to PCB copper, unlike insulated FRD packages.
What is the maximum recommended case temperature for continuous 2 A operation?
The datasheet specifies IF(AV) = 2 A at Tc = 160 °C. Operation above this requires derating per Figure 4; at Tc = 175 °C, average current must be reduced to ≤1.6 A to maintain reliability and avoid exceeding 175 °C junction temperature.
Does STPSC2H065B-TR require a negative bias to suppress leakage at high temperature?
No - unlike some early SiC diodes, STPSC2H065B-TR exhibits only 84 µA IR at 150 °C and VRRM, well within acceptable limits for PFC and DC/DC applications. Negative bias is unnecessary and adds circuit complexity without benefit.
Can STPSC2H065B-TR be used in parallel configurations?
Yes - its positive VF temperature coefficient (VF increases with temperature) enables natural current sharing. However, matched layout symmetry, equal trace inductance, and shared thermal plane are required to ensure balanced conduction between paralleled units.
