Product details
Overview
GBU6J-E3/45 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 6.0 A average forward current, 600 V maximum repetitive peak reverse voltage, and 175 A peak surge capability, designed for AC/DC full-wave rectification in switching mode power supplies and consumer electronics.
For engineers reviewing the GBU6J-E3/45 datasheet, GBU6J-E3/45 pinout, GBU6J-E3/45 application, or GBU6J-E3/45 equivalent, key selection criteria include its 600 V VRRM rating, 1.0 V forward voltage at 6.0 A, 5 μA reverse leakage at 25 °C, thermal resistance of 20 °C/W (RθJA), and GBU package mechanical compatibility with PCB copper pad heatsinking.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with in-line terminal arrangement. Its glass passivation ensures stable performance under humidity and thermal cycling, while the UL-recognized GBU case supports reliable soldering per JESD 22-B106 (275 °C, 10 s).
The device operates across -55 °C to +150 °C junction temperature range and delivers 6.0 A average output current when case-mounted on an aluminum heatsink at TC = 90 °C. Its 1500 VRMS dielectric strength between case and terminals enables safe isolation in mains-connected equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 420 V RMS input lines in SMPS front-end rectification. |
| IF(AV) | 6.0 A - Delivers continuous DC output current of 6 A at TC = 90 °C with heatsink mounting. |
| IFSM | 175 A - Survives single half-sine surge events (e.g., cold-start inrush), critical for adapter and printer power stages. |
| VF @ 6.0 A | 1.0 V - Total forward drop across two series diodes in conduction path, enabling low-loss rectification at rated load. |
| IR @ 25 °C | 5 μA - Low reverse leakage preserves efficiency in high-impedance hold-up circuits and standby modes. |
| RθJA | 20 °C/W - Thermal resistance from junction to ambient under PCB-mount conditions (12 mm × 12 mm copper pads, 9.5 mm lead length). |

Applications
| Monitor Power Supply | Printer SMPS |
|---|---|
Use Scenario: AC/DC conversion stage in LCD monitor internal power supply delivering +12 V and +5 V rails. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 115/230 VAC input to pulsating DC before bulk capacitance and PWM controller. Use Value: 600 V VRRM safely handles 230 VAC line surges; 6.0 A IF(AV) supports typical 30–50 W monitor loads with margin. | Use Scenario: Input rectification in laser printer main power supply with high peak-current demands during fuser heating cycles. IC Role / Device Role / Timing Role: Primary-side bridge rectifier feeding PFC or LLC stage; subjected to repeated 175 A surge events during fuser activation. Use Value: 175 A IFSM rating prevents thermal runaway during short-duration fuser current spikes. |
| Audio Equipment PSU | Home Appliance Adapter |
Use Scenario: Linear or hybrid power supply in high-fidelity audio amplifiers requiring low-noise, stable DC rails. IC Role / Device Role / Timing Role: Mains rectification stage preceding choke-input or capacitor-input filtering; low IR minimizes standby loss. Use Value: 5 μA reverse leakage at 25 °C reduces no-load power consumption and improves idle efficiency. | Use Scenario: Compact wall-mount AC/DC adapter for smart home devices (e.g., Wi-Fi hubs, LED controllers). IC Role / Device Role / Timing Role: Space-constrained bridge rectifier mounted directly on double-sided PCB with thermal copper pads. Use Value: GBU package footprint and 20 °C/W RθJA enable thermal management without external heatsink in <15 W adapters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6J-M3/45 | Halogen-free, RoHS-compliant variant with identical electrical specs and GBU package. | Required where halogen-free material declaration is mandated (e.g., EU public procurement, green OEM programs). | Select GBU6J-M3/45 when compliance documentation must include halogen-free certification per IEC 61249-2-21. |
| KBU6J | Same 600 V VRRM, 6 A IF(AV), but in KBU package (larger footprint, higher RθJC = 1.8 °C/W). | Better suited for bolt-down heatsink mounting; less optimal for compact PCB thermal pads. | Choose KBU6J only if mechanical integration requires larger case or lower junction-to-case thermal resistance. |
Compared with GBU6J-E3/45, GBU6J-M3/45 offers identical performance with halogen-free materials, while KBU6J trades smaller PCB area for improved heatsink coupling-making GBU6J-E3/45 optimal for space-constrained, copper-pad-cooled designs.

FAQ
What is the maximum operating junction temperature for GBU6J-E3/45?
The GBU6J-E3/45 has a specified operating junction temperature range of -55 °C to +150 °C. This 150 °C maximum allows sustained operation in thermally demanding environments such as enclosed printer power supplies or high-ambient audio amplifiers, provided thermal design meets derating curves in the Vishay datasheet (Document 88615).
Does GBU6J-E3/45 require a heatsink in typical applications?
GBU6J-E3/45 can operate without an external heatsink when mounted on a PCB with 12 mm × 12 mm copper pads and 9.5 mm lead length, delivering up to 3.8 A at TA = 40 °C. For full 6.0 A IF(AV) operation, Vishay specifies case temperature TC = 90 °C, which requires either a bolt-down aluminum heatsink or enhanced copper pour-so heatsink use depends on load and ambient conditions.
What does the "E3/45" suffix mean in GBU6J-E3/45?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/45" denotes tube packaging containing 20 units per tube, as confirmed in Vishay's ordering information table (Document 88615, page 2).
Is GBU6J-E3/45 suitable for 230 VAC input applications?
Yes, GBU6J-E3/45 is suitable for 230 VAC inputs: its 600 V VRRM rating exceeds the 325 V peak of 230 VAC by >80 % margin, and its 420 V VRMS rating covers standard 230 VAC RMS with safety headroom. It is widely deployed in European-market printers, monitors, and adapters.
How does the glass passivation benefit GBU6J-E3/45 in humid environments?
Glass passivation on the GBU6J-E3/45's silicon die provides hermetic protection against moisture ingress and surface contamination, significantly improving long-term reliability in high-humidity applications like kitchen appliances or tropical-region deployments-validated by accelerated life testing per industry standards cited in Vishay's qualification reports.
