Product details
Overview
GBJ8005-F from Diodes Incorporated is an 8A standard recovery bridge rectifier in GBJ package, rated for 50V repetitive peak reverse voltage (VRRM), 1.0V max forward voltage at 4A, and 170A non-repetitive surge current. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is designed for AC/DC power conversion in industrial power supplies and motor control PCBs.
For engineers reviewing the GBJ8005-F datasheet, GBJ8005-F pinout, GBJ8005-F application, or GBJ8005-F equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.6°C/W junction-to-case), surge rating for inrush handling, and RoHS-compliant lead-free plating for automated through-hole assembly.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic molded plastic (UL 94V-0) package with through-hole mounting for #6 screw. Its standard recovery characteristic (typical trr > 500ns) balances switching loss and EMI in line-frequency applications.
The device operates across –55°C to +150°C junction temperature, supports 8.0A average forward current at TC = +110°C, and delivers 55pF typical junction capacitance per element at 1MHz/4V reverse bias-critical for snubber design and input filter stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; sets minimum AC input isolation margin. |
| IF(AV) | 8.0 A @ TC = +110°C - Continuous DC output current capability with heatsink mounting. |
| VF | 1.0 V max @ 4.0A - Forward conduction loss directly impacts efficiency and thermal rise in 50/60Hz rectification. |
| IFSM | 170 A peak (8.3ms half-sine) - Withstands transformer inrush and capacitor charging surges without failure. |
| RθJC | 1.6 °C/W - Thermal resistance from junction to case; requires mechanical mounting to heatsink for sustained 8A operation. |
| IR | 5 µA max @ 25°C - Low leakage preserves hold-up time in capacitive-input filters under light load. |
| VB | 50 V - Breakdown voltage confirmed at 5µA test current; validates VRRM rating compliance. |
Pinout & Package
Package: GBJ - Molded plastic, UL 94V-0, through-hole, #6 screw mountable, 6.6g weight. Terminals are tin-plated, lead-free, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One of two alternating-current input pins; connects to live/neutral side of transformer secondary. |
| AC2 | Input AC Terminal 2 | Second AC input pin; completes full-wave bridge input path with AC1. |
| + (Anode Output) | Positive DC Output | Full-wave rectified positive output node; connects to bulk capacitor anode or downstream regulator input. |
| – (Cathode Output) | Negative DC Output | Full-wave rectified negative output node; serves as circuit common/ground reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance in humid or high-bias industrial environments. |
| 1500VRMS dielectric strength | Ensures safe isolation between AC inputs and DC outputs under transient overvoltage conditions. |
| UL Recognized Component (E95060) | Validates safety compliance for end-equipment certification in North American markets. |
| RoHS 3 compliant (2015/863/EU) | Meets global environmental regulations; tin-finish leads ensure compatibility with Pb-free reflow and wave soldering. |
Applications
| Industrial Power Supply | Motor Drive Front-End |
|---|---|
Use Scenario: 50/60Hz AC-to-DC conversion in DIN-rail mounted power supplies delivering 24V/48V DC. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting transformer-isolated AC to unregulated DC bus. Use Value: 8A continuous rating and 170A surge tolerance support high-startup-current loads like solenoids and relays. | Use Scenario: Input stage of 3-phase inverter drives using single-phase AC input with choke-filtered DC link. IC Role / Device Role / Timing Role: Standard-recovery bridge providing low-conduction-loss rectification prior to bulk capacitance. Use Value: 1.0V VF at 4A minimizes heat generation in compact enclosures where forced air cooling is unavailable. |
| LED Driver Power Stage | Appliance Control Board |
Use Scenario: Off-line LED driver for commercial lighting with passive PFC and constant-current regulation. IC Role / Device Role / Timing Role: Primary rectifier feeding high-voltage DC bus for flyback or buck-boost controller IC. Use Value: 50V VRRM provides sufficient margin above 35V peak AC input (24V RMS), reducing risk of avalanche failure. | Use Scenario: Embedded control board in washing machines or HVAC systems requiring isolated 12V/5V auxiliary supply. IC Role / Device Role / Timing Role: Through-hole mounted bridge rectifier on main PCB for robustness against vibration and thermal cycling. Use Value: UL recognition and –55°C to +150°C operating range ensure compliance and reliability in harsh appliance environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same 8A/50V rating, but GBU package (smaller footprint, lower I²t = 100A²s vs 120A²s). | Suitable for space-constrained designs; reduced surge margin may require derating in high-inrush applications. | Select when PCB area is critical and surge events are infrequent or clamped externally. |
| KBU8B (Comchip) | Identical GBJ package and 8A/50V rating; VF = 1.1V max (0.1V higher), IR = 10µA max (2× higher leakage). | Acceptable for cost-sensitive consumer-grade equipment where minor efficiency loss is tolerable. | Choose for price-driven BOMs where 0.1V VF penalty and elevated leakage do not impact system hold-up or thermal budget. |
Compared with GBU8K and KBU8B, GBJ8005-F offers superior surge robustness (120A²s I²t) and lowest leakage (5µA), making it preferred for industrial power supplies requiring long-term reliability under repeated line transients.

FAQ
What is the maximum operating temperature for GBJ8005-F?
The GBJ8005-F has a specified junction temperature range of –55°C to +150°C. Its 8.0A average forward current rating is guaranteed only when case temperature is maintained at +110°C or below, requiring appropriate heatsinking per the 1.6°C/W RθJC value.
Is GBJ8005-F suitable for use in automotive applications?
GBJ8005-F is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949-certified manufacturing traceability. While it meets RoHS and UL requirements, Diodes explicitly states that automotive-grade variants require direct consultation with their applications team for qualified parts.
How does the GBJ package differ from KBPC or GBU packages?
The GBJ package is larger than GBU and features screw-mount capability (for #6 screws) and higher thermal mass, yielding lower RθJC (1.6°C/W vs ~2.5°C/W for GBU). Unlike KBPC, GBJ uses molded plastic instead of ceramic-metal construction, offering better cost and moisture resistance but lower voltage standoff than ceramic-packaged bridges.
Can GBJ8005-F replace GBJ801-F in a design?
No-GBJ801-F is rated for 100V VRRM, while GBJ8005-F is rated for 50V. Substituting the 50V part in a 100V-design risks reverse-biased avalanche failure during line transients or no-load conditions. Voltage ratings are not interchangeable; always match or exceed the original VRRM requirement.
