Product details
Overview
STTH8L06G-TR from STMicroelectronics is a 600 V, 8 A ultrafast high-voltage rectifier diode in D2PAK (TO-263) package, optimized for boost-stage PFC in discontinuous/critical conduction mode and freewheeling in SMPS. It delivers typ. 0.85 V forward voltage at 150 °C, 75 ns reverse recovery time, and 2.5 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH8L06G-TR datasheet, STTH8L06G-TR pinout, STTH8L06G-TR application, or STTH8L06G-TR equivalent, key selection criteria include reverse recovery performance under high dI/dt, thermal impedance in surface-mount power layouts, conduction loss modeling at 8 A average current, and compatibility with automated reflow profiles for D2PAK assembly.
Technical Context
The STTH8L06G-TR employs ST's Turbo 2 silicon technology to achieve soft, ultrafast recovery with typ. 75 ns trr and low IRM (7.2 A) at 125 °C under 100 A/µs dI/dt. Its design targets high-frequency switching topologies where reverse recovery charge (Qrr) and softness factor (S ≥ 0.8) directly impact EMI and MOSFET stress.
It operates across -40 to +175 °C junction temperature, with VF tightly specified (0.85–1.05 V at 150 °C, 8 A) and IR limited to 200 µA at VRRM and 150 °C - enabling stable operation in thermally constrained industrial power supplies and server PSUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V AC input PFC stages with 50 % safety margin against line surges |
| IF(AV) | 8 A at Tc = 150 °C - defines continuous DC output capability in boost diode position |
| trr (typ) | 75 ns - enables >100 kHz PFC operation with minimal switching loss and voltage overshoot |
| VF (typ) | 0.85 V at 150 °C, 8 A - reduces conduction loss to ~6.8 W in high-temp ambient conditions |
| Rth(j-c) | 2.5 °C/W - allows 30 W dissipation with ≤75 °C case-to-ambient delta under copper pad cooling |
| IR (max) | 200 µA at 150 °C, 600 V - ensures low leakage-induced standby loss in offline converters |
| Qrr (typ) | 120 nC at 125 °C - quantifies stored charge cleared during turn-off, critical for snubber sizing |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated tab (epoxy-insulated), 3-pin configuration: anode, cathode, and thermal pad (electrically connected to cathode). Designed for high-current PCB trace routing and thermal transfer via large copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward conduction | Connected to switch node in boost topology; must withstand full VRRM during off-state |
| Cathode (Pin 2) | Output terminal for forward conduction | Electrically tied to thermal pad; routed to output capacitor and ground plane for low-inductance return path |
| Thermal Pad (Bottom) | Thermal and electrical connection to cathode | Requires minimum 10 cm² copper area for Rth(j-a) ≤ 30 °C/W; not isolated from cathode |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (75 ns typ.) | Minimizes turn-off energy loss and EMI generation in >100 kHz PFC controllers |
| Soft recovery (S factor ≥ 0.8) | Reduces voltage ringing and MOSFET drain stress during diode commutation |
| Low VF drift with temperature | Stable 0.85–1.05 V range from 25–150 °C enables predictable conduction loss modeling |
| ECOPACK® compliant packaging | Meets RoHS and halogen-free requirements without compromising thermal or mechanical robustness |
| High surge rating (120 A IFSM) | Withstands cold-start inrush and transient overloads in 1–2 kW power supplies |
Applications
| Server PSU Boost Stage | Industrial AC-DC Adapter |
|---|---|
Use Scenario: 1 kW active PFC front-end operating in critical conduction mode with 50–100 kHz switching. IC Role / Device Role / Timing Role: Boost rectifier handling 8 A average output current and absorbing 600 V reverse blocking stress. Use Value: 75 ns trr and soft recovery reduce MOSFET VDS overshoot by ≥35 % versus standard fast diodes, lowering snubber losses. | Use Scenario: 500 W enclosed industrial adapter with wide-input (85–264 VAC) and forced-air cooling. IC Role / Device Role / Timing Role: Freewheeling diode in LLC resonant secondary synchronous rectification stage. Use Value: 2.5 °C/W Rth(j-c) enables 25 °C lower junction temperature vs. TO-220FPAC alternatives at same board layout, extending lifetime. |
| Telecom Rectifier Module | EV Charger Auxiliary Power Supply |
Use Scenario: 3 kW telecom rectifier with distributed PFC and modular DC-DC conversion. IC Role / Device Role / Timing Role: High-reliability boost diode in each 1 kW PFC module, operating continuously at 135 °C case temperature.

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 |
|---|---|---|---|
| STTH8R06DJF-TR | Same VRRM/IF(AV), but TO-252 (DPAK); Rth(j-c) = 3.5 °C/W; trr = 65 ns typ. | Better recovery speed but higher thermal resistance - suited for space-constrained, lower-power (<500 W) designs. | Select when board area is limited and peak dI/dt exceeds 150 A/µs; avoid if thermal pad copper area <6 cm². |
| IXYS MUR860E | 600 V/8 A; trr = 70 ns typ.; VF = 1.15 V @ 25 °C; no soft recovery data published. | Higher VF increases conduction loss by ~1.2 W at 8 A; unverified softness may increase EMI in sensitive EMC environments. | Acceptable for cost-sensitive, non-EMI-critical industrial supplies; not recommended for server-grade PFC where soft recovery is mandatory. |
Compared with STTH8R06DJF-TR and IXYS MUR860E, the STTH8L06G-TR offers optimal balance of thermal performance (2.5 °C/W), verified soft recovery (S ≥ 0.8), and proven reliability in high-power PFC modules - making it preferred for 80 PLUS Titanium-certified and telecom-grade power systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STTH8L06G-TR supports continuous operation with case temperature up to 150 °C, as specified in Table 2 for D2PAK package. At this temperature, its average forward current remains rated at 8 A, and reverse leakage stays within 200 µA at 600 V. Thermal design must ensure junction temperature does not exceed 175 °C under worst-case ambient and power dissipation.
Does the D2PAK thermal pad require solder mask opening or exposed copper?
Yes - the thermal pad on the STTH8L06G-TR must be soldered directly to an unmasked, solid copper area on the PCB. ST recommends ≥10 cm² of 2-oz copper with thermal vias to internal ground planes. Solder mask over the pad impedes thermal transfer and risks voiding, increasing Rth(j-c) beyond the rated 2.5 °C/W.
Can STTH8L06G-TR replace STTH8L06D in existing TO-220AC designs?
No - STTH8L06G-TR uses D2PAK (TO-263) surface-mount packaging, while STTH8L06D is through-hole TO-220AC. They differ in footprint, thermal interface, mounting method, and mechanical stress tolerance. Direct replacement requires PCB redesign, reflow profile validation, and thermal simulation to confirm equivalent junction temperature rise.
Is the device suitable for use in automotive under-hood applications?
No - the STTH8L06G-TR is not qualified to AEC-Q101 and lacks automotive-specific qualification (e.g., extended temperature testing, humidity bias, or vibration validation). ST explicitly states in the datasheet that non-automotive-grade parts are used in automotive applications at the user's own risk, and it is not recommended for under-hood deployment where ambient exceeds 105 °C or reliability demands exceed industrial grade.
