Product details
Overview
STBR3008WY from STMicroelectronics is an AEC-Q101-qualified 800 V, 30 A automotive-grade bridge rectifier diode in DO-247 package, featuring ultra-low conduction losses (VF typ. 1.0 V at 30 A, 25 °C), high junction temperature capability (+175 °C), and guaranteed VRRM across -40 to +175 °C. It serves as the input bridge in on-board chargers (OBC) and EV charging stations where ruggedness and thermal stability are critical.
For engineers reviewing the STBR3008WY datasheet, STBR3008WY pinout, STBR3008WY application, or STBR3008WY equivalent, key selection criteria include its 350 A non-repetitive surge rating, 0.35 °C/W junction-to-case thermal resistance (DO-247), creepage distance ≥5.38 mm (with top coating), AEC-Q101 qualification, and ECOPACK2 environmental compliance.
Technical Context
This device implements a monolithic single-phase bridge configuration with four integrated high-voltage diodes optimized for unidirectional AC-to-DC conversion in high-reliability automotive power systems. Its design targets sustained operation under high ambient temperatures and repetitive surge stress, supported by validated thermal performance up to +175 °C junction temperature.
The DO-247 package provides enhanced creepage (≥5.38 mm anode-to-cathode with top coating) and mechanical robustness for high-voltage isolation, while the ultra-low VF and IR characteristics minimize conduction and reverse recovery losses-critical for efficiency in OBC front-end rectification stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - guarantees reliable blocking under worst-case line transients in 400–690 VAC charging inputs |
| IF(AV) | 30 A at TC = 160 °C - supports continuous DC output current in compact OBC designs with forced-air or heatsink cooling |
| VF (typ.) | 1.00 V at IF = 30 A, Tj = 25 °C - enables low conduction loss (~30 W total for full bridge at 30 A avg) |
| IFS M | 350 A at tp = 10 ms sinusoidal - withstands inrush surges during grid connection in charging station AC input stage |
| Tj range | -40 to +175 °C - allows deployment in engine bay–adjacent or under-hood power modules without derating |
| Rth(j-c) | 0.35 °C/W (DO-247) - enables efficient heat transfer to external heatsink, reducing thermal margin risk in sealed enclosures |
| CdA-K | 5.38 mm min. (with top coating) - meets IEC 60664-1 reinforced insulation requirements for 800 V systems |
Pinout & Package
STBR3008WY is housed in a DO-247 package-a high-power, isolated, bolt-down surface-mount variant with integrated anode/cathode terminals and UL94 V0 epoxy molding. The package features a 0.8 N·m recommended torque spec and 3.55–3.65 mm mounting hole diameter.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode (K1) | DC+ output terminal | Delivers rectified positive output; rated for full IF(AV) and IFSM current |
| Cathode (K2) | DC– output terminal / AC return | Serves as DC common return and second AC input path; completes bridge topology |
| Case (Metal tab) | Thermal & electrical ground reference | Electrically connected to K2; must be mounted to heatsink with insulating washer if isolation required |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MURB3080CT | 800 V, 30 A; TO-247 package; VF = 1.25 V (typ.); Rth(j-c) = 0.45 °C/W; not AEC-Q101 qualified | Lacks automotive qualification and lower thermal performance; suitable for industrial-only deployments | Select when cost sensitivity outweighs automotive compliance and thermal margin requirements |
| Vishay VS-30CPH08 | 800 V, 30 A; TO-247AC; VF = 1.15 V (typ.); Rth(j-c) = 0.40 °C/W; AEC-Q101 qualified but no creepage data published | No documented creepage distance; requires external isolation measures for 800 V reinforced insulation | Choose only when board-level creepage enhancement (e.g., slots, coatings) can be implemented |
Compared with MURB3080CT and VS-30CPH08, STBR3008WY uniquely combines AEC-Q101 qualification, 0.35 °C/W thermal resistance, and certified 5.38 mm creepage-making it the only drop-in solution for space-constrained, thermally demanding, and safety-critical automotive OBC designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STBR3008WY is rated for continuous operation with case temperature (TC) up to 160 °C, as specified in the absolute maximum ratings table for IF(AV) = 30 A. Exceeding this temperature requires derating per the derating curve in Figure 1 of DS13076, and thermal design must maintain junction temperature ≤ +175 °C under worst-case load and ambient conditions.
Is STBR3008WY pin-compatible with other DO-247 bridge rectifiers?
STBR3008WY uses the standard DO-247 mechanical outline defined in Table 4 of DS13076, including 3.55–3.65 mm mounting hole diameter and 0.8 N·m torque specification. While footprint dimensions match industry-standard DO-247 bridges, electrical ratings (VRRM, VF, IFSM) and thermal resistance differ-direct substitution requires validation of surge, thermal, and isolation margins.
Does STBR3008WY require external snubbers in typical OBC applications?
No external snubber is required for standard OBC operation within rated voltage and current limits. The device's low junction capacitance (typ. ~1000 pF at VR = 0 V, Figure 5) and soft reverse recovery behavior-confirmed by ST's AN4021-minimize switching noise and voltage overshoot when used with standard EMI filters and PFC chokes.
How does the DO-247 package improve thermal performance versus D²PAK HV?
The DO-247 package delivers 0.35 °C/W junction-to-case thermal resistance, 12.5% lower than the D²PAK HV variant (0.40 °C/W), due to larger copper base area and direct metal-tab thermal path. This translates to ~7 °C lower junction temperature at 30 A continuous current-critical for maintaining reliability in sealed OBC enclosures without active airflow.
