Product details
Overview
GBU6005 from Diodes Incorporated is a 6.0A standard recovery bridge rectifier with 50V maximum repetitive peak reverse voltage (VRRM), 1.0V forward voltage (VF) at 3A, and 5µA reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is designed for AC-to-DC conversion in off-line power supplies and industrial control systems.
For engineers reviewing the GBU6005 datasheet, GBU6005 pinout, GBU6005 application, or GBU6005 equivalent, key selection considerations include its 6.0A average rectified current rating with heatsink, 175A non-repetitive surge capability, thermal resistance of 2.2°C/W (junction-to-case), and UL recognition under file #E95060 for safety-critical designs.
Technical Context
The GBU6005 integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling efficient AC input rectification without external interconnection. Its standard recovery characteristic (trr not specified but implied by "standard recovery" classification) supports operation in line-frequency applications up to 60Hz with resistive or inductive loads.
Thermal performance is defined with a 50mm × 50mm × 1.6mm copper plate heatsink, supporting 6.0A IF(AV) at TJ = +150°C. Junction capacitance is 100pF at 1MHz and 4V reverse bias, indicating low high-frequency parasitic effects suitable for low-noise linear power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage ceiling (e.g., ≤35V RMS). |
| IF(AV) | 6.0 A - Average DC output current capability with heatsink; determines sustained power delivery in regulated supplies. |
| VF @ 3A | 1.0 V - Forward voltage drop per diode leg; sets conduction loss (≈2.0V total bridge drop at full load). |
| IR @ 25°C | 5 µA - Reverse leakage current; ensures minimal standby power loss and stable blocking in high-impedance circuits. |
| IFSM | 175 A - Peak surge current tolerance (8.3ms half-sine); enables robust startup handling of transformer inrush. |
| RθJC | 2.2 °C/W - Junction-to-case thermal resistance; quantifies heatsink interface efficiency for thermal design margining. |
| VB | 50 V - Breakdown voltage at 5µA IR; confirms rated VRRM compliance under test conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU601 | VRRM = 100 V (vs. 50 V); identical IF(AV), VF, and package | Supports higher AC input voltages (e.g., 70V RMS), unsuitable where 50V rating is mandated for safety margin | Select GBU601 only when system-level VRRM derating requires ≥100V blocking capability. |
| KBU6A | Same VRRM (50 V), IF(AV) = 6.0 A, but TO-220AC package (not GBU); VF = 1.1 V | Requires different PCB footprint and mounting; higher VF increases conduction loss by ~0.1 V per diode | Choose KBU6A only if TO-220 mechanical integration or alternate thermal interface is required. |
Compared with GBU6005, GBU601 offers higher reverse voltage headroom at no cost to current or thermal performance, while KBU6A trades standardized GBU footprint for TO-220 mounting flexibility and slightly higher forward loss.

FAQ
What is the maximum operating temperature for the GBU6005?
The GBU6005 has a junction operating temperature range of –55°C to +150°C. Its 6.0A average current rating assumes TJ = +150°C with a specified 50mm × 50mm × 1.6mm copper heatsink. Exceeding this temperature without adequate thermal management risks parametric shift and premature failure.
Can the GBU6005 be used without a heatsink?
Yes, but with significant current derating: the datasheet shows ~3.5A IF(AV) at TC = 75°C without heatsink, dropping to ~1.5A at TC = 100°C. For sustained 6.0A operation, a heatsink meeting the 50mm × 50mm × 1.6mm copper specification is mandatory.
Is the GBU6005 suitable for high-frequency switching applications?
No - it is a standard recovery bridge rectifier, not optimized for fast switching. Its unspecified reverse recovery time (trr) and 100pF junction capacitance indicate suitability for 50/60Hz line-frequency use only. For SMPS or PFC stages, fast- or ultrafast-recovery alternatives (e.g., GBU6K) are required.
Does the GBU6005 meet automotive qualification standards?
Not by default: the standard GBU6005 is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., GBU6005Q) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation - contact Diodes or Aetrix for qualified part numbers and change-control support.
