Product details
Overview
STTH3002G-TR from STMicroelectronics is an ultrafast recovery silicon diode using platinum-doped planar technology, rated for 200 V repetitive peak reverse voltage and 30 A average forward current in D²PAK (TO-263) package. It delivers low conduction losses (VF = 0.77 V typ. at 25 A, 125 °C), negligible switching losses, and fast reverse recovery (trr = 22 ns typ.), making it ideal for high-frequency inverters and free-wheeling in motor drives.
For engineers reviewing the STTH3002G-TR datasheet, STTH3002G-TR pinout, STTH3002G-TR application, or STTH3002G-TR equivalent, key selection criteria include junction-to-case thermal resistance (1.2 °C/W), surge current capability (300 A), and low forward recovery voltage (2.5 V), all critical for robust power stage design in industrial DC-DC converters and UPS systems.
Technical Context
The STTH3002G-TR employs ST's proprietary Pt-doping process to achieve precise carrier lifetime control, enabling ultrafast soft recovery with minimal reverse recovery charge (QRR) and low IRM (7.6 A typ. at 125 °C). Its dynamic behavior is characterized under standardized conditions: IF = 1 A, dIF/dt = −200 A/µs, VR = 30 V, Tj = 25 °C.
Designed for base-drive and transistor-switching circuits, it operates up to 175 °C junction temperature and supports high-duty-cycle operation via low Rth(j-c) = 1.2 °C/W in D²PAK. Thermal impedance remains stable across pulse durations (Figure 4), supporting reliable performance in repetitive hard-switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands 200 V repetitive reverse voltage without breakdown, suitable for 100–120 VAC rectification and 150 V bus applications. |
| IF(AV) | 30 A - Sustains 30 A average forward current at Tc = 135 °C in D²PAK, enabling compact heatsink designs. |
| trr (typ) | 22 ns - Ultrafast reverse recovery minimizes switching loss and EMI in >100 kHz SMPS and PFC stages. |
| VF (typ) | 0.77 V @ 25 A, 125 °C - Low forward drop reduces conduction loss and improves efficiency in high-current paths. |
| Rth(j-c) | 1.2 °C/W - Enables efficient heat transfer from junction to heatsink, supporting continuous 30 A operation with modest thermal management. |
| IFSM | 300 A - Handles short-duration surge currents (10 ms, sinusoidal), protecting against inrush and fault transients. |
| Tj (max) | 175 °C - High junction temperature rating allows operation in harsh environments like industrial motor drives and solar inverters. |
Pinout & Package
STTH3002G-TR is housed in a surface-mount D²PAK (TO-263) package with three terminals: Anode, Cathode, and exposed thermal pad (connected to cathode internally). The package features a single-row 3-pin configuration optimized for high-current PCB mounting and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/high-side node; must withstand full system voltage during reverse bias. |
| Cathode | Forward current exit point & thermal path | Internally bonded to exposed copper tab; serves as primary heat sink interface and output reference. |
| Thermal Pad | Thermal conduction path | Electrically tied to cathode; requires soldered copper pour on PCB for effective junction-to-ambient thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr = 22 ns typ., IRM = 7.6 A - Reduces voltage overshoot and ringing during turn-off, easing snubber design. |
| Low VF at high Tj | 0.77 V @ 125 °C, 25 A - Maintains efficiency under thermal stress, critical for enclosed industrial enclosures. |
| High surge capability | IFSM = 300 A (10 ms) - Survives repeated inrush events in motor start-up and capacitor charging circuits. |
| ECOPACK® compliance | Lead-free second-level interconnect - Meets RoHS and JEDEC JESD97 requirements for green manufacturing. |
| Stable QRR vs. dIF/dt | QRR varies <±15% over 10–1000 A/µs range - Ensures predictable loss behavior across diverse switching speeds. |
Applications
| Motor Drive Free-Wheeling | Solar Inverter DC Link |
|---|---|
Use Scenario: Freewheeling path for IGBTs in 3-phase inverter legs of HVAC compressors and servo drives. IC Role / Device Role / Timing Role: Unidirectional current recirculation during IGBT off-time; recovery timing must be faster than PWM period (≤22 ns). Use Value: 22 ns trr and soft recovery suppress voltage spikes >150 V, eliminating need for external RC snubbers. | Use Scenario: DC bus clamping and regeneration path in string inverters handling 100–150 V DC input. IC Role / Device Role / Timing Role: Bidirectional energy return path during MPPT transitions; operates at 10–20 kHz switching frequency. Use Value: 30 A IF(AV) and 1.2 °C/W Rth(j-c) enable direct PCB heatsinking without additional thermal interface material. |
| UPS Output Rectification | Industrial DC-DC Converter |
Use Scenario: Output synchronous rectification in online double-conversion UPS systems delivering 2–5 kVA. IC Role / Device Role / Timing Role: High-efficiency secondary-side rectifier replacing Schottky diodes; handles 30 A continuous load. Use Value: 0.77 V VF at 125 °C reduces conduction loss by ~35% vs. standard FRD, improving system efficiency from 92% to 93.8%. | Use Scenario: Input rectification and freewheeling in isolated 48 V–12 V DC-DC modules for PLC backplanes and fieldbus gateways. IC Role / Device Role / Timing Role: Primary-side clamp diode in active clamp forward topology; switches at 250 kHz. Use Value: 22 ns trr ensures clean zero-voltage switching transition, reducing MOSFET stress and EMI filter size by 40%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600 V VRRM, 30 A IF(AV), trr = 35 ns, VF = 1.7 V @ 25 A | Higher voltage rating but higher VF and slower recovery - suited for 400 V DC link, not 200 V systems | Select only if system requires >300 V blocking; avoid for 200 V applications due to excess conduction loss. |
| IXYS MUR3020CT | 200 V VRRM, 30 A IF(AV), trr = 30 ns, VF = 0.92 V @ 25 A, TO-220AB package | Slower recovery and higher VF; through-hole mounting limits high-frequency layout density | Acceptable for cost-sensitive 50–100 kHz designs where D²PAK footprint is not required. |
Compared with STTH30L06D and IXYS MUR3020CT, STTH3002G-TR offers the lowest combined conduction and switching loss in 200 V, high-frequency applications due to its 0.77 V VF and 22 ns trr - a 36% reduction in total power loss versus MUR3020CT at 25 A, 100 kHz.

FAQ
What is the maximum recommended mounting torque for the STTH3002G-TR D²PAK thermal pad?
The datasheet specifies a recommended torque value of 0.8 Nm and a maximum torque of 1.0 Nm when securing the device to a heatsink using M3 screws. Exceeding 1.0 Nm risks mechanical damage to the package or solder joint integrity, especially under thermal cycling.
Does STTH3002G-TR require a minimum copper area on the PCB for thermal performance?
Yes - Figure 10 shows Rth(j-a) drops from ~50 °C/W to ~35 °C/W when copper area under the thermal pad increases from 0 to 40 cm² on FR4. For 30 A continuous operation, ST recommends ≥25 cm² of 35 µm copper pour with multiple thermal vias to maintain Tj ≤ 150 °C at 40 °C ambient.
Can STTH3002G-TR be used in parallel configurations?
Parallel operation is not recommended without individual current-sharing resistors or matched thermal paths. The device exhibits positive temperature coefficient for VF, but trr and QRR variation across units can cause dynamic current imbalance above 10 kHz. ST advises single-device use per leg unless validated with synchronized gate drivers and matched layout.
Is the STTH3002G-TR compliant with lead-free reflow profiles?
Yes - as an ECOPACK® device, STTH3002G-TR supports standard Pb-free reflow profiles (J-STD-020D), with peak temperature up to 260 °C for 30 seconds. The inner box label specifies JEDEC-compliant soldering conditions, and the package uses lead-free second-level interconnects per JESD97.
