Product details
Overview
GBU1006 from Diodes Incorporated is a 10A, 600V standard recovery bridge rectifier in GBU package, featuring 1.0V max forward voltage at 5A, 5µA max reverse leakage at 25°C, and 220A non-repetitive surge rating. It delivers high dielectric strength (1500VRMS), glass-passivated die construction, and is optimized for AC/DC power supplies in industrial control and appliance mains input stages.
For engineers reviewing the GBU1006 datasheet, GBU1006 pinout, GBU1006 application, or GBU1006 equivalent, key selection criteria include VRRM=600V, IF(AV)=10A at TC=100°C, thermal resistance RθJC=2.2°C/W, surge capability IFSM=220A, and UL recognition (E95060) for safety-critical board-level rectification.
Technical Context
This single-phase, full-wave bridge rectifier uses four series-connected silicon diodes in a monolithic GBU plastic package with through-hole mounting. Its standard recovery characteristic (trr not specified, typical for general-purpose bridges) supports 50/60Hz line-frequency operation without snubbing in resistive or inductive loads.
Designed for PCB mounting with #6 screw hole and 5.0 inch-pounds max torque, it operates across –55°C to +150°C junction temperature and exhibits 60pF typical junction capacitance per diode at 1MHz/4V reverse bias - critical for EMI filtering and low-noise DC bus generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive peak reverse voltage; defines safe AC input voltage ceiling (e.g., 424V RMS sine wave). |
| IF(AV) | 10 A at TC = +100°C - Average forward current rating under heatsink conditions; requires thermal management for sustained load. |
| VF Max | 1.0 V @ 5A, 25°C - Forward voltage drop per diode pair; determines conduction loss (≈5W total at 5A full-wave). |
| IR Max | 5 µA @ 600V, 25°C - Reverse leakage current; ensures minimal standby power loss in off-state. |
| IFSM | 220 A (8.3ms half-sine) - Non-repetitive surge rating; withstands inrush currents from transformer-charged capacitors. |
| RθJC | 2.2 °C/W - Junction-to-case thermal resistance; enables thermal design using external heatsink or copper plane area. |
| CT | 60 pF @ 1MHz, 4V - Junction capacitance per diode; impacts high-frequency noise coupling and EMI filter sizing. |
Pinout & Package
Package: GBU - 4-pin, single-in-line (SIP), through-hole plastic package with integrated mounting hole (for #6 screw), matte tin-plated terminals, UL 94V-0 rated material, and approximate weight of 3.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One AC input node; connects to live/phase side of transformer secondary or mains input. |
| AC2 | Input AC Terminal 2 | Second AC input node; completes full-wave bridge input path with AC1. |
| + (Anode Common) | Positive DC Output | Full-wave rectified positive output; feeds bulk capacitor or downstream regulator. |
| – (Cathode Common) | Negative DC Output | Full-wave rectified negative/return path; establishes DC ground reference point. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1006W (Diodes Inc.) | Same electrical specs but surface-mount GBU-W package; no mounting hole; 2.5mm lead pitch. | Requires rework of PCB layout; unsuitable for screw-mounted heatsinking. | Select when space-constrained layouts or automated assembly demand SMT compatibility. |
| KBU1006 (ON Semiconductor) | Identical VRRM, IF(AV), VF, and IFSM; same GBU package; minor differences in RθJC (2.5°C/W vs 2.2°C/W) and IR (10µA vs 5µA). | No functional impact in most 50/60Hz applications; slightly higher leakage may affect ultra-low-power standby. | Drop-in replacement where Diodes' supply chain is constrained; verify thermal margin in high-ambient designs. |
Compared with GBU1006, GBU1006W enables SMT automation but sacrifices mechanical mounting flexibility, while KBU1006 offers identical performance with marginally higher thermal resistance and leakage - both viable where footprint or sourcing diversity is prioritized over exact Diodes-spec compliance.

FAQ
What is the maximum case temperature for continuous 10A operation?
The GBU1006 is rated for 10A average forward current at TC = +100°C. Operation above this temperature requires derating per Figure 1 in DS30052: at TC = +125°C, IF(AV) drops to ~7.5A; at TC = +150°C, it falls to ~5.5A. Thermal design must ensure case temperature remains within limits using appropriate copper area or heatsink.
Does GBU1006 support capacitive-load applications?
No - the datasheet explicitly states that for capacitive loads, the average forward current must be derated by 20%. At full 10A rating, this means limiting to 8A when feeding large bulk capacitors directly after rectification, due to higher peak currents and associated thermal stress on the die.
Is GBU1006 qualified for automotive use?
GBU1006 is not AEC-Q101 qualified. While it operates from –55°C to +150°C, Diodes specifies that automotive-grade parts require explicit AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing - none of which apply to standard GBU1006. Use only in non-safety-critical automotive auxiliary systems if fully validated by the customer.
How is polarity marked on the GBU1006 package?
Polarity is marked on the body with a white band indicating the cathode common (–) terminal. The AC1 and AC2 terminals are unmarked but located symmetrically on either side of the band; the + terminal is opposite the band, aligned with the mounting hole centerline. This matches standard GBU orientation per Diodes' package outline drawing.
