Product details
Overview
STTH30RQ06G-TR from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in D²PAK package, designed for secondary-side LLC full-bridge rectification with soft recovery behavior, 30 ns max reverse recovery time, and 1.45 V typical forward voltage at 150 °C - deployed in industrial UPS, air conditioning PFC stages, and EV charging station output stages.
For engineers reviewing the STTH30RQ06G-TR datasheet, STTH30RQ06G-TR pinout, STTH30RQ06G-TR application, or STTH30RQ06G-TR equivalent, key selection criteria include junction-to-case thermal resistance (0.70 °C/W), creepage distance compliance (5.38 mm min. anode–cathode with top coating), soft recovery factor stability across dIF/dt, and ECOPACK2 environmental compliance in D²PAK HV variants.
Technical Context
This ultrafast rectifier employs platinum-doped silicon to achieve controlled minority-carrier lifetime, enabling low trr (30 ns max) while maintaining soft recovery (S-factor >1.0 up to 500 A/µs) and low IR (800 µA max at 150 °C). Its dynamic performance is optimized for zero-voltage switching (ZVS) operation in resonant LLC converters.
The device supports high-reliability operation at TJ = 175 °C with Rth(j-c) = 0.70 °C/W (D²PAK), and features enhanced creepage (5.38 mm anode–cathode with top coating per IEC 60664-1) - critical for 600 V isolation in compact industrial power supplies and EV charging infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive peak reverse voltage up to 600 V, enabling use in 400 V DC bus systems with safety margin. |
| IF(AV) | 30 A at TC = 103 °C - Sustains average forward current of 30 A under heatsink-controlled thermal conditions. |
| trr (max) | 30 ns - Enables high-frequency switching (>100 kHz) with minimal turn-off loss and EMI generation. |
| VF (typ.) | 1.45 V at IF = 15 A, TJ = 150 °C - Low conduction loss improves efficiency in high-power PFC and LLC rectification stages. |

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 |
|---|---|---|---|
| STTH30R06D | TO-220AC package, Rth(j-c) = 0.85 °C/W, no creepage enhancement, 200 A IFSM | Lower-cost through-hole alternative for non-isolated, lower-density designs with forced-air cooling | Select when mechanical robustness and manual assembly outweigh creepage and thermal performance needs. |
| IXYS MUR3060CT | D²PAK dual-diode configuration, VF = 1.7 V (typ.), trr = 35 ns (max), no ECOPACK2 certification | Suitable for cost-sensitive dual-output supplies but lacks soft recovery optimization for ZVS topologies | Choose only if dual-cathode layout is required and soft recovery is not critical to EMI or efficiency targets. |
Compared with STTH30R06D and MUR3060CT, the STTH30RQ06G-TR delivers superior thermal performance (0.70 vs. 0.85 °C/W), certified creepage (5.38 mm), and softer recovery - making it the preferred choice for high-reliability, high-density, and safety-critical 600 V rectification where ZVS operation and long-term thermal stability are mandatory.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The STTH30RQ06G-TR is rated for continuous operation up to TJ = 175 °C, verified per absolute maximum ratings in DS12164 Rev 5. This allows full 30 A IF(AV) derating only at case temperatures above 103 °C, supporting sealed or passively cooled industrial designs without active thermal management.
Does the D²PAK package provide electrical isolation between the tab and pins?
No - the metal tab is internally connected to the anode. Electrical isolation must be achieved externally using insulating thermal pads or isolated mounting hardware. The 5.38 mm creepage distance applies only between anode (tab) and cathode (pin 2), not to pin 1 (NC), which is fully isolated but unused.
How does soft recovery behavior impact EMI in high-frequency LLC converters?
Soft recovery (S-factor >1.0) limits di/dt during turn-off, reducing high-frequency ringing and voltage overshoot across switching FETs. Measured data shows trr remains stable ≤30 ns and IRM stays ≤11 A even at dIF/dt = −200 A/µs - directly lowering conducted EMI and easing filter design in 100–300 kHz LLC systems.
Is the STTH30RQ06G-TR suitable for synchronous rectification replacement?
No - it is a unidirectional silicon PN junction rectifier, not a MOSFET-based synchronous device. While its ultrafast trr and low VF support high-efficiency operation, it cannot be actively controlled like a synchronous rectifier. For synchronous designs, ST recommends the STL110N10F7 or similar trench-gate MOSFETs paired with dedicated gate drivers.
