Product details
Overview
STTH12R06G-TR from STMicroelectronics is a 600 V, 12 A ultrafast high-voltage rectifier diode in D2PAK package, featuring 25 ns max reverse recovery time, 1.4 V typical forward voltage at 125 °C, and 175 °C maximum junction temperature. It is engineered for continuous-conduction-mode PFC boost stages and hard-switching freewheeling applications in industrial AC/DC power supplies.
For engineers reviewing the STTH12R06G-TR datasheet, STTH12R06G-TR pinout, STTH12R06G-TR application, or STTH12R06G-TR equivalent, key selection criteria include trr ≤ 25 ns at 25 °C, IRM = 7.0 A at 125 °C, softness factor S = 0.2, Qrr = 180 nC, and Rth(j-c) = 1.7 °C/W - all critical for minimizing switching loss and EMI in high-frequency SMPS designs.
Technical Context
This Turbo 2 silicon diode employs optimized carrier lifetime control to achieve ultrafast recovery with low IRM and soft recovery behavior (S = 0.2), reducing voltage overshoot and snubber stress. Its 600 V VRRM rating supports universal-input offline PFC front-ends up to 400 V DC bus.
Thermally, it delivers 1.7 °C/W junction-to-case resistance in D2PAK, enabling 12 A average forward current at Tc = 125 °C without forced cooling. Dynamic parameters are characterized under standardized dIF/dt conditions (e.g., −200 A/µs at 125 °C), ensuring predictable performance in real-world hard-switching environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in 400 V DC bus PFC circuits with safety margin. |
| IF(AV) | 12 A at Tc = 125 °C - Sustains continuous conduction mode PFC output current without derating. |
| trr (max) | 25 ns at Tj = 25 °C - Enables >100 kHz switching with minimal turn-off loss and EMI generation. |
| VF (typ) | 1.4 V at Tj = 125 °C, IF = 12 A - Low conduction loss improves efficiency in high-current freewheeling paths. |
| IRM (typ) | 7.0 A at Tj = 125 °C, VR = 400 V - Limits peak reverse current during diode turn-off, reducing gate drive stress on companion MOSFETs. |
| Qrr | 180 nC - Quantifies stored charge removed during recovery; directly impacts switching loss and snubber sizing. |
| Rth(j-c) | 1.7 °C/W - Enables direct heatsink mounting in D2PAK for thermal management without thermal interface pads in many cases. |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated tab; single-anode, single-cathode configuration; tab is electrically connected to cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Connects to switch node (e.g., PFC inductor output); carries full load current during conduction phase. |
| Pin 2 (Cathode) | Cathode connection | Connects to DC bus (e.g., bulk capacitor + terminal); serves as return path for forward current. |
| Tab (Cathode) | Thermal & electrical cathode | Provides primary heat path to PCB copper pour; must be routed to cathode net for electrical isolation integrity. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| STTH12R06D | TO-220AC through-hole package; Rth(j-c) = 1.7 °C/W same, but requires mechanical mounting and hole drilling. | Preferred where serviceability, manual rework, or legacy board compatibility is required. | Select when board assembly uses through-hole processes or thermal mass of leadframe aids low-frequency thermal cycling reliability. |
| STTH12R06FP | TO-220FPAC package; Rth(j-c) = 4.4 °C/W - higher thermal resistance limits IF(AV) to 12 A only at Tc = 50 °C. | Suitable for lower-power (<600 W), space-constrained designs where footprint is prioritized over thermal headroom. | Choose only if board layout prohibits D2PAK pad area and thermal design accommodates reduced current derating. |
Compared with STTH12R06D and STTH12R06FP, the STTH12R06G-TR offers identical die performance in a surface-mount D2PAK package with optimal thermal resistance (1.7 °C/W) and tape-and-reel logistics - making it the preferred choice for automated high-volume production of 1–3 kW industrial power converters.

FAQ
What is the maximum junction temperature and how does it affect reliability?
The STTH12R06G-TR has a maximum junction temperature (Tj) of 175 °C. This rating allows sustained operation in sealed, high-ambient environments (e.g., 70 °C ambient with 100 °C rise), extending mean time between failures (MTBF) by reducing thermal stress on the silicon die and metallization. Derating curves in Figure 9 confirm parameter stability up to this limit.
Is the D2PAK tab electrically isolated, and what is its voltage rating?
No - the D2PAK tab is electrically connected to the cathode terminal and is not insulated. It must be mounted on a PCB copper pour tied to the cathode net. Unlike the TO-220AC ins. variant (2500 VRMS), the D2PAK version has no reinforced insulation; system-level isolation must be maintained via PCB creepage/clearance and external barriers.
How does the softness factor (S = 0.2) improve system-level EMI performance?
A softness factor of 0.2 indicates highly controlled, gradual current decay during reverse recovery - minimizing di/dt-induced voltage spikes and high-frequency ringing. This directly reduces common-mode noise on the DC bus and lowers peak amplitudes in the 30–300 MHz EMI band, easing compliance with EN 55032 Class B limits without oversized input filters.
Can STTH12R06G-TR replace standard FR307 or UF4007 diodes in existing designs?
No - while functionally similar as fast rectifiers, STTH12R06G-TR operates at higher voltage (600 V vs. 400 V/1000 V), higher current (12 A vs. 3 A), and significantly faster recovery (25 ns vs. 500 ns). Direct replacement risks overstress due to mismatched thermal design, PCB pad layout, and snubber requirements; redesign validation is mandatory.
