Product details
Overview
STPSC10H065B-TR from STMicroelectronics is a 10 A, 650 V silicon carbide (SiC) Schottky power diode in DPAK package, designed for high-frequency hard-switching PFC and DC-DC converters. It delivers zero reverse recovery charge, temperature-independent switching behavior, and 90 A non-repetitive surge capability at 25 °C case temperature - enabling robust operation in LLC resonant and boost topologies.
For engineers reviewing the STPSC10H065B-TR datasheet, STPSC10H065B-TR pinout, STPSC10H065B-TR application, or STPSC10H065B-TR equivalent, key selection criteria include its 1.56 V forward voltage at 10 A/25 °C, 480 pF junction capacitance at 0 V, 28.5 nC capacitive charge at 400 V, 1.25 °C/W junction-to-case thermal resistance, and ECOPACK®2 environmental compliance.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-efficiency SMPS stages by eliminating reverse recovery losses. Its wide bandgap enables stable 650 V blocking with low QCJ and negligible ringing during turn-off - critical for >100 kHz PFC and LLC designs.
The DPAK package provides optimized thermal conduction (Rth(j-c) = 1.25 °C/W max) and mechanical compatibility with automated SMT assembly. Unlike PN-junction diodes, its unipolar conduction avoids minority-carrier storage, making switching performance invariant across –40 to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in universal-input PFC stages and 400 V bus DC-DC converters without derating. |
| IF(AV) | 10 A at TC = 135 °C - Supports continuous conduction mode operation in high-power density 3–5 kW PFC modules. |
| VF | 1.56 V typ. @ 10 A, 25 °C - Reduces conduction loss vs. Si FRD (typically 2.2–2.8 V), improving efficiency by ~0.5–1.2% in 3.3 kW PFC. |
| QCJ | 28.5 nC @ VR = 400 V - Low capacitive charge minimizes turn-off ESW in hard-switched boost circuits operating up to 300 kHz. |
| Rth(j-c) | 1.25 °C/W max - Allows direct mounting on 2-layer PCB copper pours or small heatsinks for thermal management in space-constrained industrial PSUs. |
| IFSM | 90 A @ tp = 10 ms, TC = 25 °C - Withstands inrush currents during cold-start in server PSU and telecom rectifier applications. |
| Tj(max) | +175 °C - Enables reliable operation in sealed enclosures or high-ambient environments (e.g., outdoor telecom cabinets). |
Pinout & Package
DPAK (TO-252) surface-mount package with insulated tab, 3-terminal configuration, UL94 V0 epoxy molding compound, and recommended footprint per Figure 13 (DS9226 Rev 8, p.8). Thermal pad soldered to PCB copper area for optimal heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point during forward conduction | Connected to input rail (e.g., boost inductor output); requires low-inductance layout to suppress dI/dt-induced voltage spikes. |
| Cathode (Pin 2) | Current exit point during forward conduction | Connected to switching node (e.g., MOSFET drain); must be routed with minimal loop area to reduce EMI in high-dv/dt applications. |
| Tab / Exposed Pad (Pin 3) | Thermal path and electrical connection to cathode | Internally tied to cathode; must be soldered to ≥4 cm² of 35 µm copper for Rth(j-a) ≤ 35 °C/W; electrically active - isolation required if cathode is not ground-referenced. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge (Qrr = 0) | Eliminates switching loss and associated EMI in hard-switched boost/PFC, enabling higher frequency operation without snubbers. |
| Temperature-stable switching | Capacitive turn-off behavior unchanged from –40 to +175 °C - ensures consistent timing and loss profile across full industrial temperature range. |
| High surge robustness | 90 A IFSM (10 ms) supports repeated cold-starts and line transients in 3 kW+ server PSUs without derating. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant construction meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10065A-TR | Same 10 A/650 V rating but in TO-220-2L package; Rth(j-c) = 1.7 °C/W; no insulated tab. | Requires mechanical insulation kit for high-voltage isolation; less suitable for SMT-only production lines. | Select when through-hole assembly is preferred or when higher thermal margin is needed via external heatsink. |
| SS10065E-TR | 10 A/650 V SiC Schottky in DPAK; VF = 1.75 V typ. @ 10 A; QCJ = 32 nC @ 400 V; Rth(j-c) = 1.4 °C/W. | Slightly higher conduction and switching losses; lower surge rating (IFSM = 75 A). | Acceptable for cost-sensitive 1–2 kW PFC where 0.2 V VF penalty and 15 A lower surge margin are acceptable. |
Compared with C3D10065A-TR and SS10065E-TR, STPSC10H065B-TR offers the lowest VF (1.56 V), lowest QCJ (28.5 nC), and highest IFSM (90 A) in DPAK - making it optimal for high-efficiency, high-reliability 3 kW+ PFC designs requiring SMT compatibility.

FAQ
What is the maximum allowable case temperature for continuous 10 A operation?
The datasheet specifies IF(AV) = 10 A at TC = 135 °C for DPAK package. Operation above this temperature requires derating per Figure 4; at TC = 150 °C, maximum average current drops to ~7.5 A. Thermal design must ensure case temperature remains ≤135 °C under worst-case ambient and airflow conditions.
Is the exposed DPAK tab electrically isolated from the cathode?
No - the exposed thermal pad (Pin 3) is internally bonded to the cathode. It is not insulated and must be treated as an active circuit node. If cathode is not at ground potential, PCB copper under the tab must be isolated using dielectric layers or clearance gaps per IPC-2221B creepage requirements for 650 V systems.
How does STPSC10H065B-TR perform in soft-switching LLC topologies?
In LLC resonant converters, it operates primarily in ZVS conditions where reverse recovery is irrelevant. Its low Cj (480 pF at 0 V) and minimal voltage-dependent capacitance variation (Figure 6) help maintain precise resonant tank tuning and reduce circulating current losses compared to higher-Cj Si diodes.
Does this part require a gate resistor or snubber network?
No - as a Schottky diode, it has no gate terminal and exhibits no reverse recovery. Snubbers are unnecessary unless parasitic ringing arises from layout inductance. Layout best practices (short, low-inductance paths; minimized loop area between anode/cathode/tank capacitor) are sufficient for clean switching waveforms.
