Product details
Overview
GBP406 from Diodes Incorporated is a 4A standard recovery bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 2.0A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, UL 94V-0 plastic package, and is rated for operation from –55°C to +150°C. It is commonly used in AC/DC power supplies for industrial control systems requiring robust, board-mountable rectification.
For engineers reviewing the GBP406 datasheet, GBP406 pinout, GBP406 application, or GBP406 equivalent, key selection criteria include VRRM rating, thermal resistance (7.5°C/W junction-to-case), surge current capability (135A @ 8.3ms), and RoHS-compliant lead-free packaging suitable for high-reliability PCB assembly.
Technical Context
The GBP406 integrates four silicon diodes in a single-phase full-wave bridge configuration with molded plastic encapsulation and matte tin-plated leads. Its glass-passivated junction ensures stable reverse characteristics across temperature, with IR rising to 500µA at +125°C under rated VR.
Thermal performance is defined relative to a 50mm × 50mm × 2mm copper heatsink (RθJC = 7.5°C/W); derating curves specify 4.0A average forward current at TC = +90°C with heatsink, dropping to 2.1A without. Junction capacitance is 40pF at 1MHz/4V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines AC input voltage headroom in bridge applications. |
| IF(AV) | 4.0 A @ TC = +90°C with heatsink - Continuous DC output current capability under controlled thermal conditions. |
| VF Max | 1.0 V @ IF = 2.0A, TJ = +25°C - Forward conduction loss directly impacts power dissipation and efficiency in linear rectifier stages. |
| IR Max | 5 µA @ VR = 600V, TJ = +25°C - Low leakage supports stable DC bus hold-up and minimizes standby power loss. |
| IFS M | 135 A @ 8.3ms half-sine, TJ = +25°C - Surge rating determines immunity to line transients and inrush currents during cold start. |
| RθJC | 7.5 °C/W - Thermal resistance from junction to case; enables heatsink sizing for thermal management in enclosed power supplies. |
| CJ | 40 pF @ 1MHz, VR = 4V - Junction capacitance affects high-frequency noise coupling and EMI filter design near AC input stage. |
Pinout & Package
Package: GBP - 4-terminal molded plastic bridge rectifier with integrated heat-spreading base. Dimensions: 14.5mm × 10.4mm × 3.1mm (L × W × H), weight ≈1.33g. Terminals are matte tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC Input Terminal 1 | One leg of AC input; connects to primary-side transformer or line filter output; symmetrical with ~AC2. |
| ~AC2 | AC Input Terminal 2 | Second leg of AC input; completes full-wave bridge input path; polarity-independent for AC waveform. |
| +DC | Positive DC Output | Anode of internal upper diodes; delivers rectified positive output to bulk capacitor or regulator input. |
| –DC | Negative DC Output / Ground Reference | Cathode of internal lower diodes; serves as common return path and system ground reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enhances long-term reliability and moisture resistance; maintains stable VRRM and IR over temperature and humidity stress. |
| UL 94V-0 plastic housing | Meets flammability safety requirement for enclosed power equipment; eliminates need for external flame-retardant barriers. |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb); supports eco-design mandates. |
| 150°C max junction temperature | Enables operation in high-ambient environments (e.g., industrial motor drives, LED drivers) without derating penalties beyond datasheet curves. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Stage |
|---|---|
Use Scenario: Converts 230VAC mains to unregulated DC bus in DIN-rail mounted PLC power modules. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing isolated, low-leakage DC input to downstream buck converter.

Use Value: 7.5°C/W RθJC allows direct mounting to metal chassis for passive cooling-no dedicated heatsink required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same GBP package, 4A/800V VRRM, VF = 1.05V @ 2A, RθJC = 8.0°C/W | Higher VRRM suits 277VAC lighting systems; slightly higher VF increases conduction loss by ~50mW at 2A. | Select when 800V blocking margin is required and minor efficiency trade-off is acceptable. |
| KBP406 (Comchip) | Same 600V/4A rating, KBP package (slightly larger footprint), VF = 1.1V @ 2A, RθJC = 9.0°C/W | Larger package may require PCB layout revision; higher thermal resistance demands more aggressive heatsinking. | Choose only if GBP footprint compatibility is not required and cost is prioritized over thermal performance. |
Compared with GBP406, GBU4K offers higher voltage margin but slightly reduced thermal efficiency, while KBP406 matches voltage/current specs but imposes greater PCB and thermal design constraints due to package size and higher RθJC.

FAQ
What is the maximum operating temperature for GBP406?
The GBP406 has a specified junction temperature range of –55°C to +150°C. Its maximum continuous case temperature is +90°C when delivering 4.0A average forward current with an appropriate heatsink. Without heatsink, derating reduces usable current to 2.1A at the same case temperature.
Is GBP406 suitable for automotive applications?
The GBP406 is not AEC-Q101 qualified and is not recommended for automotive powertrain or safety-critical systems. Diodes offers AEC-Q101-qualified alternatives (e.g., GBU4J series) for such applications; GBP406 is intended for industrial, commercial, and consumer equipment.
How does GBP406 differ from fast recovery bridge rectifiers?
GBP406 uses standard recovery diodes with typical reverse recovery time (trr) > 1.5µs, making it unsuitable for high-frequency switching (>20kHz). Fast recovery bridges (e.g., GBU4J) feature trr < 500ns and lower stored charge, reducing switching losses in SMPS designs.
Can GBP406 be used without a heatsink?
Yes-GBP406 can operate without a heatsink, but its average forward current must be derated to 2.1A at TC = +90°C. For sustained 4.0A operation, a heatsink with ≤7.5°C/W thermal resistance (e.g., 50mm × 50mm × 2mm Cu plate) is required per datasheet Figure 1.
