Product details
Overview
GBU610 from Diodes Incorporated is a 6.0A, 1000V standard recovery bridge rectifier in GBU package, featuring 1.0V max forward voltage at 3A, 5µA max reverse leakage at 25°C, and 175A peak surge rating - used for AC/DC conversion in industrial power supplies and motor control front-ends.
For engineers reviewing the GBU610 datasheet, GBU610 pinout, GBU610 application, or GBU610 equivalent, key selection criteria include VRRM=1000V, IF(AV)=6.0A with heatsink, VF≤1.0V @3A, IR≤5µA @25°C, and IFSM=175A - critical for high-voltage off-line rectification under thermal and surge stress.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a single GBU plastic package with glass-passivated junctions. It operates across -55°C to +150°C junction temperature and delivers 6.0A average output current when mounted on a 50mm×50mm copper heatsink.
Designed for resistive or inductive loads at 60Hz, it requires 20% current derating for capacitive loads. Its 1500VRMS case dielectric strength and UL94V-0 flammability rating support safety-critical PCB mounting in mains-connected equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage withstand before breakdown; defines safe AC input range up to ~707V RMS. |
| IF(AV) | 6.0 A - average rectified output current with heatsink; enables continuous DC output of ~6A in 50/60Hz power supplies. |
| VF Max | 1.0 V @ 3A - forward voltage drop per diode leg; determines conduction loss (≈3W total at 3A full-wave). |
| IR Max | 5 µA @ 25°C - reverse leakage current; ensures minimal standby power loss in high-impedance hold-up circuits. |
| IFSM | 175 A - non-repetitive peak surge current (8.3ms half-sine); sustains inrush into bulk capacitors without failure. |
| RθJC | 2.2 °C/W - thermal resistance junction-to-case; allows thermal design using heatsink area and interface material. |
| TJ Range | -55°C to +150°C - operational junction temperature range; supports deployment in industrial enclosures without forced cooling. |
Pinout & Package
Package: GBU - molded plastic through-hole package with 4 leads, UL94V-0 rated, lead-free tin-plated terminals, 3.7g weight, and #6 screw mounting capability (5.0 in-lb max torque).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One AC input node; connects to live/phase side of transformer secondary or line filter. |
| AC2 | Input AC Terminal 2 | Second AC input node; completes full-wave bridge input path with AC1. |
| + (Anode Common) | DC Positive Output | Full-wave rectified positive output; ties internally to anode ends of two diodes. |
| – (Cathode Common) | DC Negative Output | Full-wave rectified negative output; ties internally to cathode ends of two diodes. |

Applications
| Industrial Power Supply | Motor Drive Front-End |
|---|---|
Use Scenario: Off-line AC/DC conversion in 100–500W industrial SMPS with universal input (85–265VAC). IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC line to unregulated DC bus prior to PFC stage.

Use Value: -55°C to +150°C TJ range ensures operation inside sealed, thermally stressed enclosures; RoHS compliance meets regional regulatory mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 6A/1000V rating, but VF = 1.1V max @3A; RθJC = 2.5°C/W; no UL file number listed. | Lacks UL recognition; slightly higher conduction loss and thermal resistance limit high-density layouts. | Select when UL certification is not required and cost sensitivity outweighs thermal margin. |
| KBU6K (Comchip) | Identical VRRM/IF(AV)/IFSM ratings; VF = 1.05V max @3A; IR = 10µA max @25°C; RoHS compliant. | Doubles reverse leakage vs. GBU610; may increase standby loss in energy-sensitive designs. | Acceptable where leakage <10µA is acceptable and sourcing diversity is prioritized. |
Compared with GBU6K and KBU6K, GBU610 offers lower IR (5µA), certified UL recognition, and superior thermal resistance (2.2°C/W), making it preferred for safety-critical, thermally constrained, or low-standby-power industrial systems.

FAQ
What is the maximum heatsink-less operating current for GBU610?
Without a heatsink, GBU610 is rated for 3.0A average forward current at 25°C ambient, per Figure 1 derating curve. At 70°C case temperature, this drops to approximately 1.8A. Thermal design must account for PCB copper area, airflow, and enclosure ambient - sustained operation above 3A without heatsinking risks exceeding 150°C junction temperature.
Does GBU610 support capacitive-input filter designs?
Yes, but with mandatory 20% current derating per datasheet Note. For a 6.0A rated device, maximum average current in capacitive-input configurations is 4.8A. This accounts for higher RMS current and peak diode stress caused by narrow conduction angles - essential for reliable operation with bulk electrolytic capacitors.
Is GBU610 qualified to AEC-Q101 for automotive use?
No - GBU610 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade variants require separate qualification (AEC-Q100/101/104/200), PPAP capability, and IATF 16949 manufacturing. Standard GBU610 is intended for industrial, commercial, and consumer applications only.
What is the recommended PCB pad layout for GBU610's thermal performance?
Mount GBU610 on a minimum 50mm × 50mm × 1.6mm copper plate heatsink, as specified in Note 4. Use thermal vias under the central tab area (if present), maximize copper pour on both layers, and avoid solder mask over thermal pads. Mechanical mounting via #6 screw (5.0 in-lb max torque) ensures optimal case-to-heatsink contact for the stated 2.2°C/W RθJC.
