Product details
Overview
STTH30RQ06G2-TR from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in D²PAK HV package, designed for LLC full-bridge secondary-side rectification with soft recovery behavior, 30 ns max reverse recovery time, and 1.45 V typical forward voltage at 15 A/150 °C - deployed in industrial UPS, air conditioning inverters, and EV charging station PFC stages.
For engineers reviewing the STTH30RQ06G2-TR datasheet, STTH30RQ06G2-TR pinout, STTH30RQ06G2-TR application, or STTH30RQ06G2-TR equivalent, key selection criteria include junction-to-case thermal resistance (0.70 °C/W), creepage distance (5.38 mm anode-to-cathode with top coating), soft recovery factor, and ECOPACK2 compliance for high-reliability power conversion designs.
Technical Context
This ultrafast rectifier employs planar epitaxial silicon technology optimized for high-voltage switching applications. Its soft recovery behavior minimizes EMI generation during turn-off, while low reverse leakage (<800 µA at 150 °C) ensures stable operation under elevated temperature stress in continuous conduction mode converters.
The device supports high dIF/dt rates up to 500 A/µs with controlled reverse recovery current (8–11 A at 125 °C) and charge (485 nC), enabling efficient operation in resonant topologies where di/dt-induced voltage overshoot must be suppressed without snubbers.

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-insulated, lower-power (<1.5 kW) designs with adequate heatsinking | Select when board space permits through-hole mounting and creepage >5.38 mm is not mandated by safety standard. |
| IXYS MUR3060CT | D²PAK package, 600 V/30 A, trr = 35 ns (max), Rth(j-c) = 0.80 °C/W, no HV creepage spec | Compatible footprint but lacks certified creepage distance; suited for non-mains-isolated or lower-safety-class systems | Choose only if IEC 60664-1 reinforced insulation is not required and thermal margin allows higher Rth. |
Compared with STTH30R06D and MUR3060CT, STTH30RQ06G2-TR uniquely delivers certified 5.38 mm creepage in surface-mount D²PAK HV format with superior thermal performance (0.70 °C/W) and tighter trr control - essential for high-efficiency, safety-compliant industrial and EV infrastructure designs.

FAQ
What is the maximum junction temperature and how does it impact thermal design?
The STTH30RQ06G2-TR has a maximum junction temperature of 175 °C. This allows operation at higher ambient temperatures or with reduced heatsink size compared to 150 °C-rated diodes. Thermal design must ensure junction temperature remains below this limit under worst-case conduction and switching loss conditions, using the specified 0.70 °C/W Rth(j-c) and accounting for PCB copper area and airflow.
Is the D²PAK HV package pin-compatible with standard D²PAK footprints?
No - the D²PAK HV package has identical outline dimensions to standard D²PAK but features modified internal die placement and creepage-enhanced molding compound. Its footprint matches standard D²PAK (e = 2.54 mm pitch), but layout must observe the 5.38 mm minimum anode-to-cathode creepage requirement on the PCB surface, which may necessitate wider isolation slots or conformal coating.
How does the soft recovery behavior benefit LLC resonant converter designs?
Soft recovery minimizes the rate of change of reverse current (di/dt) during turn-off, reducing voltage overshoot across the diode and adjacent switches. In LLC converters, this lowers EMI generation, eliminates need for RC snubbers, and prevents false triggering of overvoltage protection - directly improving system efficiency and reliability at high switching frequencies (100–500 kHz).
Can STTH30RQ06G2-TR replace STTH30RQ06G-TR in existing designs?
Yes - both share identical electrical specifications and D²PAK footprint, but STTH30RQ06G2-TR adds certified 5.38 mm creepage distance (with top coating) per IEC 60664-1. Replacement is mechanically and electrically compatible; however, designs targeting reinforced insulation must verify that PCB layout and coating meet the enhanced creepage requirement to fully leverage the safety advantage.
