Product details
Overview
STTH8R06G-TR from STMicroelectronics is an ultrafast high-voltage silicon rectifier diode in D²PAK (TO-263) package, rated for 600 V repetitive peak reverse voltage and 8 A average forward current at Tc = 130 °C. It features 25 ns maximum reverse recovery time, 1.4 V typical forward voltage at 125 °C/8 A, and low thermal resistance (2.2 °C/W junction-to-case), optimized for continuous-conduction-mode PFC boost stages in industrial SMPS.
For engineers reviewing the STTH8R06G-TR datasheet, STTH8R06G-TR pinout, STTH8R06G-TR application, or STTH8R06G-TR equivalent, this device is selected for high-efficiency, hard-switching AC-DC front-ends where low trr, soft recovery (S factor = 0.3), and reduced switching losses are critical - especially in 1–3 kW server PSUs and telecom rectifiers.
Technical Context
The STTH8R06G-TR employs ST's Turbo 2 600 V process to achieve ultrafast recovery with controlled softness, minimizing EMI and voltage overshoot during turn-off. Its dynamic performance is characterized at IF = 8 A, dIF/dt = –200 A/µs, VR = 400 V, and Tj = 125 °C - yielding 5.5 A typical reverse recovery current and 150 nC reverse recovery charge.
Thermally, it delivers Rth(j–c) = 2.2 °C/W in D²PAK, enabling high-power density designs without forced airflow. The device operates up to 175 °C junction temperature and maintains <400 µA reverse leakage at 125 °C, supporting robust operation in thermally constrained industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands 600 V repetitive reverse voltage, suitable for universal-input (85–265 VAC) PFC stages with 400 V DC bus margin. |
| IF(AV) | 8 A at Tc = 130 °C - Sustains continuous 8 A conduction in D²PAK when heatsink maintains 130 °C case temperature. |
| trr (max) | 25 ns - Enables high-frequency (>100 kHz) switching with minimal turn-off loss and reduced snubber requirements. |
| VF (typ) | 1.4 V at 8 A / 125 °C - Low forward drop reduces conduction loss to ~11.2 W at full load, improving system efficiency. |
| Rth(j–c) | 2.2 °C/W - Allows direct mounting to PCB copper or heatsink; 10 W dissipation raises junction only 22 °C above case. |
| S factor | 0.3 - Soft recovery minimizes di/dt-induced ringing and EMI, easing EMC compliance in dense power layouts. |
| Qrr | 150 nC - Low stored charge reduces energy loss during commutation, critical for ZVS/ZCS topologies. |
Pinout & Package
STTH8R06G-TR uses the surface-mount D²PAK (TO-263) package: a 3-pin, single-ended, isolated-tab configuration with exposed cathode pad for thermal and electrical connection. The molded epoxy body meets UL94 V0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward current flow | Connected to PFC inductor node; carries full AC line-referenced switching current. |
| Cathode (Lead 2) | Output terminal for forward current flow | Connected to +400 V DC bus; electrically and thermally tied to large copper pour or heatsink via exposed pad. |
| Tab / Exposed Pad | Cathode (internally bonded) | Primary thermal path; must be soldered to ≥100 mm² 2-oz copper for rated Rth(j–c); also serves as high-current cathode return. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 25 ns max trr enables >150 kHz PFC operation with minimal switching loss penalty. |
| Soft recovery profile | S factor = 0.3 ensures gradual current decay, suppressing voltage spikes and reducing snubber size/cost. |
| Low thermal resistance | 2.2 °C/W (j–c) in D²PAK allows 8 A operation with passive cooling on 4-layer PCBs. |
| High junction temperature rating | 175 °C max Tj supports operation in sealed enclosures or high-ambient industrial environments. |
| ECOPACK® compliant | Meets RoHS and halogen-free requirements without compromising thermal or switching performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06D | Same die, TO-220AC through-hole package; Rth(j–c) = 2.2 °C/W but requires mechanical mounting and wire leads. | Preferred for prototyping, lower-volume industrial controls, or where manual assembly or socketing is required. | Select when board-level rework, thermal interface flexibility, or lead-forming is needed over automated SMT placement. |
| IXYS MUR860E | 600 V / 8 A ultrafast diode; trr = 35 ns (max), VF = 1.75 V (typ @ 8 A/25 °C), Rth(j–c) = 3.0 °C/W in TO-220AC. | Higher VF and slower recovery increase conduction and switching loss in high-frequency PFC; less suitable for 150+ kHz designs. | Consider only if STTH8R06G-TR supply is constrained and thermal budget permits higher losses. |
Compared with STTH8R06D, the STTH8R06G-TR offers identical electrical specs in a space-saving, thermally superior SMT package; versus MUR860E, it delivers 10 ns faster recovery, 0.35 V lower VF at elevated temperature, and 0.8 °C/W better thermal resistance - directly enabling higher power density and efficiency in modern PFC designs.

FAQ
What is the maximum junction temperature and how does it impact reliability?
The STTH8R06G-TR has a maximum junction temperature of 175 °C. Operating consistently below this limit ensures long-term reliability under thermal stress; its 125 °C-rated VF and 150 nC Qrr remain stable up to this point, making it suitable for sealed or high-ambient industrial enclosures without active cooling derating.
Is the D²PAK tab electrically isolated from the leads?
No - the exposed D²PAK tab is internally bonded to the cathode (Lead 2). It is not insulated and must be treated as a live high-current cathode node. PCB layout must assign the tab to the +400 V DC bus net and avoid accidental shorting to ground or adjacent signals.
How does the softness factor affect EMI performance?
A softness factor of 0.3 means the reverse recovery current decays gradually rather than abruptly, reducing di/dt-induced voltage spikes across stray inductance. This directly lowers broadband conducted EMI, easing compliance with EN 55022 Class B and reducing snubber capacitor size by up to 40% in compact PFC layouts.
Can STTH8R06G-TR replace STTH8R06FP in TO-220FPAC?
No - while both share the same die, STTH8R06G-TR (D²PAK) and STTH8R06FP (TO-220FPAC) have incompatible packages, thermal paths, and mounting methods. D²PAK offers lower Rth(j–c) but requires reflow-compatible PCB layout; TO-220FPAC needs screw mounting and thermal grease. Direct substitution is not mechanically or thermally valid.
