Product details
Overview
STTH15RQ06G2-TR from STMicroelectronics is a 600 V, 15 A ultrafast recovery rectifier diode in D²PAK HV package, optimized for high-voltage secondary rectification in LLC full-bridge topologies and PFC stages. It delivers soft reverse recovery (trr ≤ 25 ns at 25 °C), low VF (1.45 V max at 15 A/150 °C), and high junction temperature capability (Tj(max) = 175 °C), enabling efficient operation in air conditioning inverters and EV charging station power supplies.
For engineers reviewing the STTH15RQ06G2-TR datasheet, STTH15RQ06G2-TR pinout, STTH15RQ06G2-TR application, or STTH15RQ06G2-TR equivalent, key selection criteria include reverse recovery time under high dIF/dt, thermal resistance (Rth(j-c) = 1.5 °C/W), creepage distance (5.38 mm anode-to-cathode with coating), and softness factor for EMI-sensitive switching converters.
Technical Context
This diode implements a Turbo 2 silicon process to achieve ultrafast recovery with controlled softness (S-factor > 1.0 at 125 °C), minimizing voltage overshoot and ringing during turn-off in hard-switched LLC resonant converters. Its low QRR (250 nC typical) and low IR (400 µA max at 150 °C) reduce both switching and conduction losses in high-frequency PFC and output rectification stages.
The D²PAK HV package provides enhanced isolation with minimum 5.38 mm creepage between anode and cathode (with top coating), meeting IEC 60664-1 requirements for reinforced insulation in 600 V systems. Junction-to-case thermal resistance of 1.5 °C/W supports direct heatsink mounting without thermal interface material in industrial-grade designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V DC bus applications with safety margin. |
| IF(AV) | 15 A - Average forward current rating at TC = 115 °C, defining continuous conduction capability in rectifier legs. |
| trr (max) | 25 ns - Maximum reverse recovery time at IF = 0.5 A, IR = 1 A, Irr = 0.25 A, 25 °C; enables <100 kHz switching with low loss. |
| VF (max) | 1.45 V - Max forward voltage at IF = 15 A, Tj = 150 °C; determines conduction loss (P ≈ 1.05×IF(AV) + 0.053×IF²(RMS)). |
| Rth(j-c) | 1.5 °C/W - Junction-to-case thermal resistance; allows ~15 W dissipation with 22.5 °C case-to-ambient rise at rated current. |
| CdA-K | 5.38 mm - Minimum creepage distance (anode to cathode) with top coating in D²PAK HV package, supporting reinforced insulation per IEC 60664-1. |
| Tj (max) | 175 °C - Maximum operating junction temperature; enables reliable operation in high-ambient environments like motor drives and UPS. |
Pinout & Package
D²PAK HV (High Voltage) package: surface-mount, isolated tab, epoxy body meeting UL94 V0, with creepage-enhanced layout for 600 V isolation. Tab is cathode-connected; leads are anode (pin 1) and cathode (pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Forward current input | Connects to high-side switching node (e.g., LLC transformer secondary center-tap or PFC boost output); carries full load current. |
| Pin 2 (Cathode) | Forward current output / Heat sink interface | Connects to output rail (e.g., +VOUT); electrically and thermally coupled to heatsink via isolated metal tab. |
| Tab (Cathode) | Primary thermal path & electrical return | Must be mounted to heatsink with torque-controlled screw (0.55–0.70 N·m for TO-220AC variant; D²PAK HV uses soldered thermal pad); no isolation required for cathode circuit. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr ≤ 25 ns with S-factor > 1.0 ensures low EMI and reduced snubber stress in high-dI/dt LLC converters. |
| High-temperature operation | Tj(max) = 175 °C enables use in enclosed, high-ambient environments (e.g., HVAC inverters, UPS enclosures) without derating. |
| Low thermal resistance | Rth(j-c) = 1.5 °C/W allows direct heatsink coupling and simplifies thermal design for 15 A continuous loads. |
| Enhanced creepage isolation | 5.38 mm anode-to-cathode creepage (D²PAK HV with coating) meets reinforced insulation requirements for 600 V AC mains-connected systems. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant construction supports environmental compliance in industrial and automotive-adjacent applications. |
Applications
| LLC Resonant Converter Output Rectification | PFC Boost Diode in Industrial SMPS |
|---|---|
Use Scenario: High-efficiency 1–3 kW server PSU or telecom rectifier using asymmetric half-bridge LLC topology with synchronous rectification not feasible. IC Role / Device Role / Timing Role: Ultrafast freewheeling diode on secondary side, conducting during transformer reset phase with minimal reverse recovery loss. Use Value: Soft trr and low QRR reduce voltage spikes across primary switches and lower EMI filter cost versus standard fast recovery diodes. |
Use Scenario: 3.3 kW active PFC front-end in industrial UPS or solar string inverter with 400 V DC bus. IC Role / Device Role / Timing Role: Boost rectifier handling 15 A average current at 100 kHz switching, requiring low conduction loss and fast turn-off. Use Value: VF(max) = 1.45 V at 150 °C reduces conduction loss by ~12% vs. legacy 1.65 V diodes, improving system efficiency by 0.4–0.6%. |
| EV Onboard Charger (OBC) Secondary Side | Air Conditioning Inverter DC Link Clamp |
Use Scenario: 6.6 kW bidirectional OBC with dual-phase LLC topology where secondary-side rectification must handle 15 A RMS at 200–500 kHz. IC Role / Device Role / Timing Role: High-voltage output rectifier converting resonant transformer AC to regulated DC, operating at elevated ambient temperatures. Use Value: Tj(max) = 175 °C and Rth(j-c) = 1.5 °C/W allow stable operation at 115 °C case temperature without forced cooling. |
Use Scenario: 3-phase HVAC inverter with 600 V DC link, requiring clamping diodes to suppress IGBT turn-off voltage spikes. IC Role / Device Role / Timing Role: Snubber/clamp diode absorbing inductive energy during IGBT commutation, demanding fast recovery and high surge tolerance. Use Value: IFSM = 120 A (10 ms) and soft recovery prevent snap-off failure and limit dv/dt-induced gate stress on adjacent IGBTs. |
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 |
|---|---|---|---|
| STTH15R06DJ-TR | D²PAK (non-HV) package; creepage = 3.48 mm (no top coating), Rth(j-c) = 1.5 °C/W identical. | Lacks reinforced insulation; unsuitable for mains-connected PFC or OBC secondary where 5.38 mm creepage is mandated. | Select only for isolated DC-DC or low-isolation-risk applications where space constraints preclude TO-220AC. |
| IXYS MUR1560CT | TO-220AB dual-diode package; VF = 1.7 V (max @ 15 A/125 °C); trr = 35 ns (max); no soft recovery data published. | Higher conduction loss and harder recovery increase EMI and snubber loading; requires larger heatsink due to higher Rth(j-c). | Use only if dual-diode configuration is needed or D²PAK footprint is incompatible; verify EMI compliance in final layout. |
Compared with STTH15R06DJ-TR, STTH15RQ06G2-TR adds critical creepage for safety-critical AC-input systems; versus MUR1560CT, it delivers lower VF, faster trr, and documented softness-enabling higher efficiency and simpler EMI filtering in LLC and PFC designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device is rated for IF(AV) = 15 A at TC = 115 °C, meaning sustained case temperature must not exceed 115 °C under full load. At higher case temperatures, derating is required per Figure 1 and Figure 2 in DS12162; operation up to TC = 130 °C is possible with reduced current (e.g., ~12 A at 130 °C).
Is the D²PAK HV package lead-free and RoHS compliant?
Yes, STTH15RQ06G2-TR is ECOPACK®2 certified, confirming halogen-free, lead-free, and RoHS-compliant construction. The D²PAK HV package uses matte tin plating on leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30 °C/85% RH.
How does the soft recovery behavior impact EMI performance?
Soft recovery (S-factor > 1.0) limits di/dt during turn-off, reducing high-frequency ringing and voltage overshoot across switching devices. This directly lowers conducted EMI in the 30–100 MHz band and relaxes filtering requirements-verified in ST application note AN4021 for reverse loss analysis.
Can this diode replace STTH15RQ06G-TR in existing designs?
Yes-STTH15RQ06G2-TR is a direct drop-in replacement for STTH15RQ06G-TR in D²PAK HV footprint layouts. Both share identical electrical specs and thermal resistance; G2-TR adds enhanced creepage (5.38 mm vs. 3.48 mm in standard D²PAK), making it suitable for higher-isolation applications without layout change.
