Product details
Overview
STPSC8H065G-TR from STMicroelectronics is an 8 A, 650 V silicon carbide (SiC) Schottky power diode in D²PAK package, designed for high-frequency hard-switching PFC and DC-DC converters. It delivers zero reverse recovery charge, temperature-independent switching behavior, 75 A non-repetitive surge current (tp = 10 ms), and 23.5 nC total capacitive charge at 400 V - enabling efficient operation in LLC resonant and boost topologies.
For engineers reviewing the STPSC8H065G-TR datasheet, STPSC8H065G-TR pinout, STPSC8H065G-TR application in PFC stages, or STPSC8H065G-TR equivalent SiC diodes, this page provides verified thermal resistance (Rth(j-c) = 1.3 °C/W typ.), forward voltage (VF = 1.56 V @ 8 A, 25 °C), junction temperature limit (175 °C), insulated package options, and real-world surge robustness data.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-efficiency AC-DC front-ends. Its wide bandgap enables a 650 V blocking rating with near-zero Qrr and negligible turn-off ringing - eliminating snubbers and reducing EMI in 65–100 kHz PFC designs.
The D²PAK package provides low thermal resistance (1.3 °C/W typ. junction-to-case) and supports conduction-cooled mounting on heatsinks. Its 414 pF junction capacitance at 0 V and 38 pF at 400 V ensures predictable soft-switching behavior across operating voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - maximum repetitive reverse voltage; defines safe operation in 400 VAC input PFC bus with margin. |
| IF(AV) | 8 A - average forward current at Tc = 140 °C; determines continuous conduction capability in boost inductor path. |
| VF @ 8 A, 25 °C | 1.56 V (typ.) - forward drop directly impacts conduction loss; enables <1.3 W loss at 8 A using P = 1.35×IF(AV) + 0.144×IF²(RMS). |
| Qcj @ 400 V | 23.5 nC - total capacitive charge; governs turn-off energy loss and EMI generation in hard-switched boost stages. |
| Rth(j-c) | 1.3 °C/W (typ.) - thermal resistance from junction to case; enables 10.4 W dissipation before reaching 175 °C junction limit at 95 °C case. |
| IFSM (10 ms) | 75 A - non-repetitive surge current at Tc = 25 °C; ensures survival during line transients and startup inrush. |
| Tj(max) | 175 °C - maximum junction temperature; allows operation in high-ambient industrial environments without derating. |
Pinout & Package
D²PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection. Insulated variants use TO-220AC Ins; this part uses standard D²PAK with solderable tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to switch node in boost topology; requires low-inductance layout to minimize voltage overshoot. |
| Cathode (Tab / Pin 2) | Forward current exit / heat sink interface | Electrically and thermally connected to output rail and PCB copper pour; must be soldered to ≥100 mm² 2-oz copper for Rth(j-c) compliance. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery charge (Qrr ≈ 0) | Eliminates switching losses and associated EMI in hard-switched PFC, enabling >98% efficiency at 65 kHz. |
| Temperature-stable switching | Capacitive turn-off behavior unchanged from −40 °C to +175 °C - no derating needed across industrial ambient range. |
| High surge robustness | 75 A IFSM (10 ms) withstands repeated line surges and inrush events without degradation in server/industrial SMPS. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free reflow requirements - qualified for automotive-grade manufacturing processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D08065E (Wolfspeed) | Same 8 A / 650 V rating; Rth(j-c) = 1.5 °C/W (higher); VF = 1.65 V @ 8 A, 25 °C. | Slightly higher conduction loss; identical surge rating (75 A) but lower thermal performance limits peak power density. | Prefer when legacy layout uses same footprint and thermal design margin exists. |
| SS12065A (Littelfuse) | 8 A / 650 V; VF = 1.70 V @ 8 A, 25 °C; Qcj = 25.2 nC @ 400 V; Rth(j-c) = 1.4 °C/W. | Higher Qcj increases turn-off loss in high-frequency (>80 kHz) PFC; lower surge rating (65 A) reduces transient headroom. | Select only if cost sensitivity outweighs efficiency and reliability requirements in non-critical applications. |
Compared with C3D08065E and SS12065A, STPSC8H065G-TR offers the lowest VF and Qcj among 8 A/650 V D²PAK SiC diodes, delivering superior conduction efficiency and reduced EMI - critical for high-density, high-efficiency PFC designs where thermal headroom is constrained.

FAQ
What is the maximum recommended case temperature for continuous operation?
The STPSC8H065G-TR is rated for IF(AV) = 8 A at Tc = 140 °C per datasheet Table 1. Operating above this temperature requires linear derating: at 150 °C case, max IF(AV) drops to ~6.8 A. Thermal design must ensure junction stays ≤175 °C under worst-case load and ambient conditions.
Does this diode require a gate resistor or driver circuit?
No - STPSC8H065G-TR is a passive uncontrolled Schottky diode with no gate terminal. It conducts when anode voltage exceeds cathode voltage by >VF and blocks when reverse biased. Unlike MOSFETs or IGBTs, it has no control signal, gate drive, or switching timing constraints.
Can it replace a standard silicon fast recovery diode in an existing PFC design?
Yes, with layout review: the D²PAK footprint matches many Si FRDs, but SiC's zero Qrr eliminates snubber networks and reduces MOSFET voltage stress. Verify thermal interface (copper area, solder paste volume) meets Rth(j-c) spec, and confirm layout inductance is minimized to avoid voltage overshoot during diode turn-on.
Is the D²PAK variant electrically insulated like the TO-220AC Ins version?
No - STPSC8H065G-TR in D²PAK has a conductive metal tab (cathode) that must be electrically isolated from heatsink via insulating pad or coating. The TO-220AC Ins variant provides 2500 VRMS isolation; D²PAK relies on external insulation for high-voltage safety compliance.
