Product details
Overview
GBU10005 from Diodes Incorporated is a 10A standard recovery bridge rectifier in GBU package, rated for 50V repetitive peak reverse voltage (VRRM), 1.0V max forward voltage at 5A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and 220A non-repetitive surge capability-used in AC/DC power supplies for industrial control panels requiring robust line-frequency rectification.
For engineers reviewing the GBU10005 datasheet, GBU10005 pinout, GBU10005 application, or GBU10005 equivalent, key selection criteria include VRRM margin for 24VAC input derating, thermal resistance (2.2°C/W junction-to-case), through-hole mounting torque limit (5.0 in-lb), and UL recognition (E95060) for safety-compliant board-level integration.
Technical Context
This single-phase, full-wave bridge rectifier uses four series-connected standard recovery diodes in a monolithic plastic package. Its 220A 8.3ms surge rating supports motor-start transients, while the 60pF typical junction capacitance minimizes high-frequency noise coupling in 50/60Hz applications.
The device operates across –55°C to +150°C junction temperature range and requires derating to ~7A at TC = +100°C per Figure 1. Mounting on a 100mm × 100mm × 1.6mm copper heatsink enables its rated 10A average forward current under resistive or inductive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Withstands 50V repetitive reverse voltage; suitable for ≤35V RMS AC inputs with safety margin. |
| IF(AV) | 10 A @ TC = +100°C - Sustains 10A average DC output current when case temperature held at 100°C with heatsink. |
| VF Max | 1.0 V @ IF = 5A - Limits conduction loss to ≤5W per half-cycle at 5A; impacts thermal design and efficiency. |
| IR Max | 5 µA @ VR = 50V, TJ = +25°C - Ensures minimal standby power loss in off-state; critical for low-power hold-up circuits. |
| IFS M | 220 A (8.3ms half-sine) - Handles inrush surges from transformer-coupled or capacitive-input supplies without failure. |
| RθJC | 2.2 °C/W - Dictates minimum heatsink size required to maintain TJ ≤ 150°C under full load. |
| VB | 50 V @ IR = 5µA - Confirms breakdown threshold aligns with VRRM rating; validates voltage-clamping integrity. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same GBU package, 50V VRRM, but 1.1V VF max @ 5A and 10µA IR max @ 25°C. | Slightly higher conduction loss and leakage; acceptable where thermal margin exists. | Prefer GBU10005 when <1.0V VF or <5µA IR is required for efficiency-critical or low-power-hold designs. |
| KBU1005 (Comchip) | Identical 50V/10A rating, but 2.5°C/W RθJC and no UL recognition. | Requires larger heatsink; not suitable for safety-certified end products needing UL file validation. | Select GBU10005 for designs requiring UL E95060 compliance or tighter thermal management. |
Compared with GBU10K and KBU1005, GBU10005 offers the lowest forward voltage and reverse leakage among 50V/10A GBU bridges, plus UL recognition-making it optimal for thermally constrained, safety-certified industrial power supplies where efficiency and regulatory alignment are prioritized.

FAQ
What is the maximum case temperature for continuous 10A operation?
GBU10005 sustains 10A average forward current only when case temperature (TC) is maintained at +100°C, as specified in the Absolute Maximum Ratings table. This requires mounting on a 100mm × 100mm × 1.6mm copper heatsink. At higher ambient or insufficient heatsinking, derating per Figure 1 applies-e.g., ~7A at TC = +125°C.
Can GBU10005 be used in capacitive-input filter configurations?
Yes, but with 20% current derating per the datasheet: maximum IF(AV) drops to 8A for capacitive loads. This accounts for higher peak currents and increased thermal stress caused by narrow conduction angles. Ensure heatsink design accommodates the resulting power dissipation increase.
Is GBU10005 suitable for automotive applications?
No-GBU10005 is not AEC-Q101 qualified. While Diodes offers automotive-grade variants (e.g., GBU10005Q), this standard version lacks PPAP documentation, IATF 16949 manufacturing evidence, and extended qualification testing. Use only in non-safety-critical, non-automotive industrial or commercial systems.
What does the "05" suffix in GBU10005 indicate?
The "05" denotes the 50V repetitive peak reverse voltage (VRRM) rating. The full part number follows Diodes' GBUxxx coding: GBU = package type, 10 = 10A current rating, 005 = 50V VRRM. Other variants include GBU1001 (100V), GBU1002 (200V), etc.-all sharing identical package, thermal, and surge characteristics.
