Product details
Overview
GBU10V08-TU from Diodes Incorporated is a 10A, 800V glass-passivated single-phase bridge rectifier in GBU package, featuring 0.92V max forward voltage at 5A and 5µA max reverse leakage at 25°C. It delivers high surge current capability (500A peak for 1.0ms) and operates across –40°C to +150°C junction temperature, ideal for AC/DC power supplies in industrial motor drives and HVAC control systems.
For engineers reviewing the GBU10V08-TU datasheet, GBU10V08-TU pinout, GBU10V08-TU application, or GBU10V08-TU equivalent, key selection criteria include repetitive peak reverse voltage (800V), average forward current with heatsink (10A), thermal resistance (2°C/W junction-to-case), low VF performance, and UL recognition (E95060).
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under transient stress. Its construction supports high IFSM ratings (500A @ 1.0ms, 220A @ 8.3ms at TJ = +125°C) and maintains stable IR up to 500µA at elevated temperature.
The GBU10V08-TU is optimized for PCB mounting without mandatory heatsinking-delivering 2.9A average forward current at TC = +100°C unheatsinked-and features matte tin-plated leads compliant with MIL-STD-202 Method 208 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands up to 800V repetitive reverse voltage without breakdown, suitable for 380VAC input systems with safety margin. |
| IF(AV) | 10 A - Sustains 10A average forward current when mounted on 150×150×2mm Cu heatsink at TC = +85°C. |
| VF Max | 0.92 V @ 5A, 25°C - Low conduction loss improves efficiency in high-current DC bus generation. |
| IR Max | 5 µA @ VR = 800V, 25°C - Minimal leakage preserves isolation integrity in standby and light-load conditions. |
| IFSM | 500 A @ 1.0ms half-sine - Handles inrush surges from large input capacitors or transformer energization. |
| RθJC | 2 °C/W - Enables precise thermal design when heatsink interface resistance is known and controlled. |

| High IFSM (500A) | Survives repeated cold-start surges in motor drive inverters without degradation, extending service life over lower-rated bridges. |
Applications
| Industrial Motor Drives | HVAC Control Power Supplies |
|---|---|
Use Scenario: Rectifying 230/400VAC three-phase line input (via external step-down transformer) to generate 550VDC bus for IGBT gate drivers and logic rails. IC Role / Device Role / Timing Role: Primary AC/DC conversion stage delivering regulated DC bus; not a timing or control device. Use Value: 800V VRRM ensures 2× safety margin over 400VAC peak (565V), while 10A IF(AV) supports continuous 750W power delivery with minimal derating. | Use Scenario: Converting 24VAC furnace control transformer output into stable 32VDC for microcontroller, relay drivers, and sensor interfaces. IC Role / Device Role / Timing Role: Single-phase bridge rectifier providing unregulated DC; no timing function involved. Use Value: Low 0.92V VF minimizes heat generation in confined HVAC control boxes, eliminating need for heatsink at ≤2A load. |
| LED Streetlight Drivers | Industrial PLC Power Modules |
Use Scenario: Front-end rectification in constant-current LED drivers operating from 277VAC line, feeding PFC and DC/DC stages. IC Role / Device Role / Timing Role: Input-stage bridge rectifier; enables high-efficiency topology by minimizing conduction loss before PFC. Use Value: 500A IFSM rating withstands repeated lamp hot-restrike surges without parameter shift or failure. | Use Scenario: Providing isolated 24VDC auxiliary power from 120/240VAC mains for PLC CPU, I/O modules, and communication interfaces. IC Role / Device Role / Timing Role: Mains-side rectification component; no signal conditioning or timing role. Use Value: UL E95060 recognition simplifies CE/UKCA marking for industrial automation equipment meeting EN 61000-6-2/4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same GBU package, 800V VRRM, but VF = 1.05V @ 5A and IR = 10µA @ 25°C. | Slightly higher conduction loss and leakage; acceptable where thermal margin exists and cost sensitivity outweighs efficiency. | Select when sourcing flexibility is prioritized and 0.13V VF penalty is tolerable in thermally relaxed designs. |
| KBU10B (Comchip) | GBU footprint compatible, 800V VRRM, VF = 0.95V @ 5A, IR = 5µA, but IFSM = 350A @ 1.0ms. | Lower surge rating reduces robustness against transformer inrush in high-inductance systems. | Prefer for cost-sensitive consumer-grade power supplies where peak surge events are infrequent and well-clamped. |
Compared with GBU10K and KBU10B, the GBU10V08-TU offers the lowest VF (0.92V), tightest IR spec (5µA), and highest IFSM (500A), making it optimal for thermally constrained, high-reliability industrial power conversion where efficiency and surge resilience are critical.

FAQ
What is the maximum case temperature for reliable operation without a heatsink?
The GBU10V08-TU sustains 2.9A average forward current at TC = +100°C without heatsink, per its derating curve. Exceeding this temperature risks thermal runaway due to rising IR and VF; operation above +100°C case requires active cooling or derating below 2.9A. Thermal resistance without heatsink is 35°C/W, so ambient must remain ≤65°C at 2.9A to hold TC ≤100°C.
Is GBU10V08-TU suitable for use in AEC-Q200 qualified automotive applications?
No-GBU10V08-TU is not AEC-Q200 qualified. While Diodes offers automotive-grade variants (e.g., GBU10V08Q), this TU suffix denotes commercial/industrial grade. For automotive use, contact Diodes directly for PPAP-capable, IATF 16949-manufactured versions with full AEC-Q200 test reports and change control documentation.
How does the GBU10V08-TU compare to GBU10V06-TU in terms of electrical performance?
Both share identical package, VF (0.92V), IR (5µA), and thermal specs. The sole difference is VRRM: GBU10V06-TU is rated for 600V, while GBU10V08-TU is rated for 800V. This makes the latter suitable for 400VAC systems (565V peak) with 1.4× safety margin, whereas the 600V version suits 277VAC (392V peak) with similar margin.
Can GBU10V08-TU be mounted directly to a PCB without mechanical fasteners?
Yes-it is designed for through-hole PCB mounting with recommended mounting torque of 0.5 N·m (max 0.8 N·m). The GBU package includes integral mounting holes; secure mechanical attachment is required for thermal and mechanical reliability, especially under vibration or thermal cycling. Solder-only mounting is insufficient for sustained 10A operation.
