Product details
Overview
STTH8R06GY-TR from STMicroelectronics is an AEC-Q101-qualified ultrafast 600 V, 8 A automotive-grade rectifier diode in D2PAK package, featuring 45 ns max reverse recovery time, 1.5 V typical forward voltage at 125 °C, and 1.9 °C/W junction-to-case thermal resistance. It serves as a boost diode in continuous-conduction-mode PFC stages and as a freewheeling diode in hard-switching SMPS.
For engineers reviewing the STTH8R06GY-TR datasheet, STTH8R06GY-TR pinout, STTH8R06GY-TR application, or STTH8R06GY-TR equivalent, key selection criteria include reverse recovery softness (S factor = 0.4), low trr under high dIF/dt (≤500 A/µs), thermal performance at Tj = 175 °C, and AEC-Q101 qualification for under-hood power conversion.
Technical Context
This device employs ST's Turbo 2 silicon technology to achieve ultrafast switching with controlled soft recovery-critical for minimizing EMI and voltage overshoot in high-frequency boost converters. Its low IRM (5.5–7.2 A) and Qrr (150 nC) reduce switching losses during turn-off transitions under hard-switching conditions.
The diode operates across –40 °C to +175 °C junction temperature, with validated thermal resistance (Rth(j-c) = 1.9 °C/W) enabling high-power density designs on standard FR4 PCBs using the D2PAK's exposed tab for heatsinking. Reverse leakage remains ≤400 µA at 125 °C and VR = 600 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in boost PFC and flyback snubber circuits without breakdown |
| IF(AV) | 8 A at Tc = 135 °C - Sustains continuous forward current in high-efficiency AC/DC front-ends |
| trr (max) | 45 ns - Enables operation up to ~500 kHz switching frequency while limiting turn-off loss |
| VF (typ) | 1.5 V at Tj = 125 °C, IF = 8 A - Low conduction loss improves system efficiency at elevated temperatures |
| Rth(j-c) | 1.9 °C/W - Allows direct thermal coupling to heatsink via D2PAK tab, supporting >20 W dissipation |
| S factor | 0.4 - Soft reverse recovery reduces ringing and EMI in high-dI/dt gate-drive and transformer reset paths |
| Qrr | 150 nC - Predictable charge removal enables accurate loss modeling in synchronous rectifier replacement analysis |
Pinout & Package
D2PAK (TO-263) package with isolated tab (pin 1 = cathode, pin 2 = anode, tab = cathode). Exposed copper pad provides low-thermal-resistance path to heatsink and meets UL94 V0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 2) | Forward current entry | Connected to switch node (e.g., MOSFET drain) in boost topology; must handle 90 A surge |
| Cathode (Pin 1 + Tab) | Forward current exit / heat path | Electrically and thermally tied to output rail and heatsink; requires insulated mounting if chassis-ground referenced |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including engine control modules and on-board chargers |
| Ultrafast trr ≤45 ns | Enables high-frequency PFC operation while maintaining low EMI and voltage stress on switching FETs |
| Low Rth(j-c) = 1.9 °C/W | Permits compact thermal design without forced air, supporting 15–25 W continuous dissipation on 25 cm² copper |
| Soft recovery (S = 0.4) | Reduces di/dt-induced voltage spikes and electromagnetic interference in unshielded power stages |
| High Tj max = 175 °C | Supports operation in sealed enclosures near power semiconductors without derating at ambient >105 °C |

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 |
|---|---|---|---|
| STTH8R06D-TR | D2PAK-3L variant with identical electrical specs but non-automotive grade (no AEC-Q101) | Lacks automotive qualification; suitable only for industrial/commercial power supplies | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| IXYS MUR860E | 600 V, 8 A, trr = 50 ns (max), VF = 1.75 V (typ), Rth(j-c) = 2.5 °C/W, no AEC-Q101 | Higher VF and thermal resistance; not qualified for automotive use | Use where slightly higher conduction loss and thermal impedance are acceptable, and automotive compliance is unnecessary |
Compared with STTH8R06D-TR and IXYS MUR860E, STTH8R06GY-TR uniquely combines AEC-Q101 qualification, 45 ns trr, and 1.9 °C/W thermal resistance-making it the only choice for thermally constrained, safety-critical automotive PFC stages requiring long-term reliability at 175 °C junction temperature.

FAQ
Is STTH8R06GY-TR pin-compatible with STTH8R06D-TR?
Yes-both use identical D2PAK-3L package with anode (pin 2), cathode (pin 1), and cathode-connected tab. Mechanical footprint, solder pad layout, and thermal mounting requirements are fully interchangeable. Electrical specifications match exactly except for AEC-Q101 qualification status.
What is the maximum recommended dIF/dt for reliable operation?
The datasheet validates performance up to 500 A/µs (see Figure 4–6). At this rate, IRM peaks at 7.2 A and trr remains ≤45 ns at Tj = 125 °C. For designs exceeding 500 A/µs, empirical testing is advised due to potential softness degradation above rated dIF/dt.
Can STTH8R06GY-TR be used in synchronous rectification topologies?
No-it is a unidirectional silicon PN junction rectifier, not a MOSFET-based synchronous device. It functions only as a passive freewheeling or boost diode. Synchronous rectification requires actively controlled N-channel MOSFETs with gate drive circuitry.
Does the "Y" suffix indicate lead-free and RoHS-compliant construction?
Yes-the "Y" in STTH8R06GY-TR denotes ECOPACK®2 lead-free, halogen-free packaging compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1. The D2PAK body uses UL94 V0 epoxy and Pb-free terminations.
