Product details
Overview
STBR3008G2Y-TR from STMicroelectronics is an AEC-Q101 qualified 800 V, 30 A automotive-grade bridge rectifier diode in D²PAK HV package, featuring ultra-low conduction losses (VF = 1.00 V typ. at 30 A, 25 °C), high junction temperature capability (+175 °C), and minimum 5.38 mm anode-to-cathode creepage distance with top coating - deployed as input bridge in on-board chargers (OBC) for EVs.
For engineers reviewing the STBR3008G2Y-TR datasheet, STBR3008G2Y-TR pinout, STBR3008G2Y-TR application, or STBR3008G2Y-TR equivalent, key selection criteria include repetitive peak reverse voltage (800 V), average forward current (30 A at TC = 160 °C), thermal resistance (0.40 °C/W junction-to-case), AEC-Q101 qualification, and D²PAK HV creepage compliance per IEC 60664-1.
Technical Context
This device implements a monolithic single-phase full-wave bridge configuration with four integrated silicon diodes optimized for high-voltage AC/DC conversion in harsh automotive environments. Its design targets stable operation across -40 to +175 °C junction temperature range while maintaining guaranteed VRRM and low IR up to 150 °C.
Thermal performance is defined by two distinct Rth(j-c) values: 0.40 °C/W for D²PAK HV and 0.35 °C/W for DO-247 - enabling precise thermal modeling based on selected package. Reverse leakage remains ≤100 µA at 150 °C and VR = VRRM, supporting reliable blocking in high-temperature charging systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - guarantees safe blocking of 800 V repetitive reverse voltage across full operating temperature range (-40 to +175 °C) |
| IF(AV) | 30 A at TC = 160 °C - defines maximum continuous DC output current under specified heatsink conditions |
| VF (typ.) | 1.00 V at IF = 30 A, Tj = 25 °C - enables low conduction loss calculation: P ≈ 0.75 × IF(AV) + 0.0073 × IF²(RMS) |
| Tj Range | -40 to +175 °C - supports operation in under-hood and OBC environments without derating below rated current |
| Rth(j-c) | 0.40 °C/W - quantifies thermal path efficiency from junction to case in D²PAK HV package for heatsink interface design |
| CdA-K | 5.38 mm min. (with top coating) - meets IEC 60664-1 creepage requirements for reinforced insulation in 800 V systems |
Pinout & Package
The STBR3008G2Y-TR is housed in a surface-mount D²PAK HV (TO-263HV) package with three terminals: Anode (A), Cathode (K1), and Cathode (K2). The package features extended creepage distance, UL94 V0 epoxy, and optimized thermal pad layout for PCB conduction cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Anode input | AC input terminal for one side of bridge; connects to primary AC source in OBC front-end |
| K1 | Cathode output (common) | DC+ output node shared by two diodes; routed to bulk capacitor positive rail |
| K2 | Cathode output (common) | DC+ output node shared by other two diodes; electrically tied to K1 internally |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per stress test plan |
| Ultra-low conduction losses | VF = 1.00 V typ. at 30 A ensures <1.5 W conduction loss at rated current (Tj = 25 °C) |
| High junction temperature rating | +175 °C max Tj enables compact thermal design without active cooling in sealed OBC enclosures |
| D²PAK HV creepage | 5.38 mm anode-to-cathode creepage with top coating satisfies reinforced insulation for 800 V AC mains isolation |
Applications
| On-Board Charger (OBC) | EV Charging Station |
|---|---|
Use Scenario: AC-to-DC front-end rectification in 6.6 kW bidirectional OBC modules. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 230 VAC/50 Hz input to unregulated DC bus. Use Value: Ultra-low VF reduces conduction loss by ~18% vs. standard 800 V diodes, lowering heatsink size and improving system efficiency at 30 A load. | Use Scenario: Input stage rectification in modular AC charging units rated for 7–22 kW. IC Role / Device Role / Timing Role: High-reliability bridge diode handling surge currents up to 350 A (10 ms sine) during grid transients. Use Value: Guaranteed VRRM over -40 to +175 °C prevents premature breakdown during ambient temperature swings in outdoor installations. |
| Industrial Motor Drive Power Supply | Renewable Energy Inverter Auxiliary Supply |
Use Scenario: Unregulated DC bus generation for gate driver and control circuitry in HVAC compressors. IC Role / Device Role / Timing Role: Bridge rectifier feeding bulk capacitor in auxiliary SMPS input stage. Use Value: ECOPACK2 compliance and 175 °C Tj support long-term reliability in enclosed motor drive cabinets with limited airflow. | Use Scenario: Rectification of transformer-derived AC for control power in solar string inverters. IC Role / Device Role / Timing Role: Isolated auxiliary supply bridge with reinforced creepage for functional safety compliance. Use Value: 5.38 mm creepage distance eliminates need for slotting or conformal coating to meet IEC 62109 creepage requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30R06D | 600 V VRRM, TO-220AC package, VF = 1.15 V typ. at 30 A | Limited to 600 V systems; lacks AEC-Q101 and creepage certification | Use only in non-automotive 600 V industrial supplies where qualification and creepage are not required |
| IXYS MURB3060CT | 600 V VRRM, TO-263 package, VF = 1.10 V typ., no AEC-Q101 | Lower voltage rating and no automotive qualification; higher VF increases conduction loss | Suitable for cost-sensitive 600 V commercial chargers lacking automotive environmental requirements |
Compared with STTH30R06D and IXYS MURB3060CT, STBR3008G2Y-TR uniquely delivers 800 V blocking, AEC-Q101 compliance, and certified creepage - making it the only viable option for automotive OBCs requiring functional safety and reinforced insulation at 800 V.

FAQ
What is the maximum surge current rating for STBR3008G2Y-TR?
The non-repetitive surge forward current (IFSM) is 350 A for a 10 ms sinusoidal pulse at Tj = 25 °C. This value decreases with increasing initial junction temperature - e.g., ~280 A at Tj = 125 °C - and must be verified against actual system transient profiles using Figure 7 from DS13076.
Is STBR3008G2Y-TR pin-compatible with other D²PAK HV bridge rectifiers?
Yes - it uses the standard 3-pin D²PAK HV footprint (A, K1, K2) with identical mechanical dimensions and thermal pad layout as ST's STBRxx series. However, electrical ratings differ: always verify VRRM, IF(AV), and VF before substitution, as internal die design affects thermal and conduction performance.
Does STBR3008G2Y-TR require external snubbers in OBC applications?
No snubber is required for typical 50/60 Hz OBC operation due to its low reverse recovery charge (Qrr) and soft recovery characteristics. However, if used in high-frequency PFC stages (>20 kHz), consult AN4021 for reverse loss analysis and consider RC snubbing based on measured dv/dt and switching waveform ringing.
How does the D²PAK HV package improve safety in 800 V systems?
The D²PAK HV package achieves 5.38 mm minimum creepage between anode and cathode terminals when coated - exceeding IEC 60664-1 requirements for reinforced insulation at 800 V. This eliminates reliance on PCB slotting or conformal coating to prevent arcing in high-humidity or contaminated environments.
