Product details
Overview
GBU4005 from Diodes Incorporated is a 4.0A standard recovery bridge rectifier with 50V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 2A, and 5µA max reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 150A non-repetitive surge current - used in AC/DC power supplies for industrial control panels requiring robust line-input rectification.
For engineers reviewing the GBU4005 datasheet, GBU4005 pinout, GBU4005 application, or GBU4005 equivalent, key selection criteria include VRRM margin for 24VAC input stages, thermal resistance (2.2°C/W junction-to-case), through-hole mounting compatibility with #6 screw, and UL recognition (E95060) for safety-critical power entry designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a molded GBU package with common-cathode and common-anode configuration. It operates under standard recovery (non-fast) switching behavior, optimized for 50/60Hz line-frequency applications rather than high-frequency SMPS.
Thermal performance is defined with a 50mm × 50mm × 1.6mm copper heatsink; derating applies for capacitive loads (−20% IF(AV)). Junction temperature range spans −55°C to +150°C, supporting operation in enclosed industrial enclosures without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Withstands 50V peak reverse voltage; suitable for ≤35V RMS AC inputs (e.g., 24VAC control transformers). |
| IF(AV) | 4.0 A @ TC = +100°C - Continuous average forward current rating when case temperature is held at 100°C using heatsink. |
| VF Max | 1.0 V @ IF = 2.0A - Forward conduction loss per diode leg; total bridge drop ≈ 2.0V at full load. |
| IR Max | 5 µA @ VR = 50V, TA = +25°C - Low leakage preserves efficiency in high-impedance bias networks and standby circuits. |
| IFSM | 150 A (8.3ms half-sine) - Handles inrush surges from transformer-coupled or capacitor-input supplies without failure. |
| RθJC | 2.2 °C/W - Thermal resistance from junction to case; enables thermal design with discrete heatsinking for sustained 4A operation. |
Pinout & Package
Package: GBU - Molded plastic, UL 94V-0 rated, through-hole mount with #6 screw hole. Dimensions: 22.05mm × 18.55mm × 7.65mm (L × W × H), weight ≈ 3.7g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~ (AC1) | AC Input Terminal 1 | One of two alternating-current input nodes; connects to live/phase side of transformer secondary. |
| ~ (AC2) | AC Input Terminal 2 | Second AC input node; connects to neutral/side of transformer secondary - forms full-wave input pair. |
| + (DC+) | Positive DC Output | Common cathode output node; delivers rectified positive voltage to bulk capacitor or regulator input. |
| – (DC–) | Negative DC Output | Common anode return node; serves as system ground reference for downstream DC circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances moisture and contamination resistance for long-term reliability in humid or dusty industrial environments. |

FAQ
What is the maximum operating temperature for GBU4005?
The GBU4005 has a junction temperature range of −55°C to +150°C and a storage temperature range matching that span. Its average forward current rating of 4.0A is specified at TC = +100°C, requiring heatsinking or PCB copper area to maintain case temperature within limit during continuous operation.
Is GBU4005 suitable for use in automotive applications?
The GBU4005 is not AEC-Q200 qualified and lacks automotive-specific qualification documentation. While it meets industrial temperature and reliability requirements, Diodes recommends contacting their automotive team for parts qualified to AEC-Q101 or PPAP-capable alternatives if used in vehicle systems.
How does GBU4005 differ from fast recovery or Schottky bridge rectifiers?
GBU4005 uses standard recovery silicon diodes with typical reverse recovery time >1.5µs, making it unsuitable for high-frequency switching. Unlike Schottky bridges, it has higher VF (~1.0V) but superior VRRM capability and lower IR at elevated temperatures - optimized for 50/60Hz line frequency, not SMPS.
What is the mechanical mounting requirement for GBU4005?
The GBU4005 uses through-hole mounting with a centered #6 screw hole. Maximum mounting torque is 5.0 inch-pounds. It must be secured to a PCB or heatsink using this screw; unsupported悬空 mounting violates mechanical stress limits and compromises thermal performance.
