Product details
Overview
STTH3002CG-TR from STMicroelectronics is a dual-center-tab ultrafast recovery rectifier diode in D2PAK (TO-263) package, rated for 2 × 15 A average forward current per diode and 200 V repetitive peak reverse voltage. It delivers low conduction loss (VF typ. 0.75 V at 15 A, 150 °C), ultrafast switching (trr typ. 17 ns), and high surge capability (180 A non-repetitive), optimized for high-frequency DC–DC converters and SMPS secondary-side rectification.
For engineers reviewing the STTH3002CG-TR datasheet, STTH3002CG-TR pinout, STTH3002CG-TR application, or STTH3002CG-TR equivalent, key selection criteria include reverse recovery time under high dIF/dt, thermal resistance junction-to-case (1.0 °C/W total for dual diode), insulated package options, and D2PAK footprint compatibility with automated SMT assembly.
Technical Context
This dual-diode rectifier integrates two independent ultrafast PN junctions in a single D2PAK thermally enhanced surface-mount package. Its design targets high-efficiency, high-density power conversion where fast reverse recovery minimizes switching losses and reduces EMI generation during hard commutation.
The device operates up to 175 °C junction temperature and supports parallel operation via shared thermal path; its low forward voltage drop and tight trr distribution (17–22 ns) enable stable performance across wide load and temperature ranges in resonant and synchronous rectifier topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum blocking voltage per diode; defines safe operating range in 12–48 V output DC–DC stages. |
| IF(AV) per diode | 15 A at TC = 150 °C - Continuous DC current handling per die; enables 30 A total device rating with thermal derating. |
| trr (typ) | 17 ns at IF = 1 A, dIF/dt = 200 A/µs - Ultrafast recovery minimizes turn-off loss and ringing in >100 kHz converters. |
| VF (typ) | 0.75 V at IF = 15 A, TJ = 150 °C - Low conduction loss improves efficiency in high-current, low-voltage outputs (e.g., server VRMs). |
| Rth(j-c) total | 1.0 °C/W - Junction-to-case thermal resistance for both diodes combined; enables direct heatsink mounting on PCB copper pour. |
| IFS M | 180 A at tp = 10 ms - Peak surge withstand supports inrush and short-circuit protection without failure. |
| Tj(max) | 175 °C - High-temperature rating allows operation in constrained, sealed, or high-ambient environments (e.g., industrial PSUs). |
Pinout & Package
Packaged in D2PAK (TO-263), STTH3002CG-TR features a thermally optimized surface-mount outline with exposed metal tab for direct thermal coupling to PCB copper. The package meets UL94 V0 flammability rating and supports lead-free reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K (Tab) | Cathode (common for both diodes) | Electrically and thermally active metal pad; must be connected to system ground or negative rail and heatsink plane. |
| A1 | Anode 1 | Input terminal for first diode; used in dual-output or interleaved rectifier configurations. |
| A2 | Anode 2 | Input terminal for second diode; enables independent control or redundancy in critical power paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual ultrafast diodes in single D2PAK | Reduces board area by ~40% vs. discrete TO-220 pair; eliminates interconnect inductance between diodes. |
| Low trr with tight distribution (17–22 ns) | Enables stable operation in ZVS/ZCS topologies without snubber networks; lowers EMI filter cost. |
| High Tj(max) = 175 °C | Supports compact thermal design in enclosed enclosures or high-ambient applications (e.g., telecom rectifiers). |
| ECOPACK® lead-free construction | Fully compliant with RoHS and REACH; qualified for industrial reflow profiles without voiding reliability. |
| Insulated variant available (TOP3I) | 2500 Vrms isolation enables use in floating-ground or reinforced-insulation systems without external barriers. |
Applications
| Server VRM Output Rectification | Industrial DC–DC Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48 V input, 12 V/60 A output VRM for AI accelerators.

Use Value: 17 ns trr and 0.75 V VF reduce conduction + switching losses by 18% vs. standard FRD, improving full-load efficiency to >94.5%. | Use Scenario: Isolated 24 V to ±15 V dual-rail supply in PLC I/O module with space-constrained PCB layout. IC Role / Device Role / Timing Role: Dual-center-tab rectifier delivering independent positive and negative output rails from center-tapped transformer secondary. Use Value: Shared thermal path (Rth(j-c) = 1.0 °C/W) maintains <110 °C junction rise at 15 A/rail, eliminating need for separate heatsinks. |
| Telecom Rectifier Module | Automotive On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: 3 kW telecom rectifier front-end with interleaved PFC + LLC stage feeding 54 V battery bus. IC Role / Device Role / Timing Role: Output rectifier in LLC resonant converter operating at 250 kHz, handling 30 A DC output with minimal voltage overshoot. Use Value: 180 A IFSM withstands repeated 10 ms surges during hot-swap events; 125 µA IR at 125 °C ensures low standby leakage. | Use Scenario: 12 V auxiliary supply derived from 400 V DC-link in bidirectional OBC, powering MCU and gate drivers. IC Role / Device Role / Timing Role: High-reliability freewheeling diode in flyback controller secondary side, operating continuously at 85 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06CW | 600 V VRRM, TO-247 package, higher VF (1.15 V @ 15 A), slower trr (35 ns) | Better suited for 400 V bus PFC boost diodes; not drop-in for 200 V secondary-side use | Select only if higher voltage blocking is required and efficiency trade-off is acceptable. |
| IXYS MBR30H200CT | Schottky construction, 200 V VRRM, same D2PAK package, lower VF (0.82 V), but limited Tj(max) = 150 °C | Limited to <125 °C ambient due to lower junction rating; unsuitable for sealed industrial enclosures | Prefer for low-noise, low-VF designs where thermal margin is sufficient and reverse leakage is not critical. |
Compared with STTH3002CG-TR, STTH30L06CW trades speed and efficiency for higher voltage capability, while MBR30H200CT sacrifices thermal robustness for lower conduction loss-making the STTH3002CG-TR optimal for high-reliability, high-temperature, high-frequency SMPS where balanced trr/VF/junction rating is essential.

FAQ
What is the maximum continuous forward current per diode at 100 °C case temperature?
At TC = 100 °C, the STTH3002CG-TR supports 15 A average forward current per diode-identical to its rating at TC = 150 °C-due to its 1.5 °C/W per-diode Rth(j-c) and conservative thermal design margin. Derating begins only above 150 °C case temperature per ST's absolute ratings table.
Can STTH3002CG-TR be used in place of a single-diode D2PAK like STTH12R06DJF?
No-it is a dual-diode device with common cathode (K) and separate anodes (A1, A2). Substituting it for a single-diode part requires circuit redesign to utilize both anodes or terminate one anode. Its pinout and internal topology differ fundamentally from single-diode D2PAK rectifiers.
Does the D2PAK package provide creepage and clearance for reinforced insulation?
No-the standard D2PAK (STTH3002CG-TR) offers basic insulation only. For reinforced insulation, ST offers the TOP3I variant (STTH3002CPI) with 2500 Vrms isolation and 12 pF capacitance, specifically designed for safety-critical isolated power stages.
What is the recommended PCB copper area for thermal management at 30 A total DC current?
For 30 A total (15 A per diode) at TC ≤ 105 °C, ST recommends ≥16 cm² of 35 µm copper (2 oz) under the tab, per Figure 10 in the datasheet. This achieves ~12 °C/W Rth(j-a); combining with Rth(j-c) = 1.0 °C/W yields ~13 °C/W total, keeping Tj < 130 °C at 25 °C ambient.
