Product details
Overview
GBJ806 from Diodes Incorporated is an 8A standard recovery bridge rectifier in GBJ package, rated for 600V repetitive peak reverse voltage (VRRM), 1.0V max forward voltage at 4A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and 170A non-repetitive surge capability-used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the GBJ806 datasheet, GBJ806 pinout, GBJ806 application, or GBJ806 equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.6°C/W junction-to-case), surge IFSM rating for inrush handling, and through-hole mounting compatibility with #6 screw fastening.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a common cathode/anode configuration to convert AC input into unidirectional DC output. Its standard recovery characteristic (non-fast, non-ultrafast) suits 50/60Hz line-frequency applications where switching loss is not critical but ruggedness and surge tolerance are prioritized.
The device operates across –55°C to +150°C junction temperature range and delivers stable performance under sustained 8A average forward current when heatsinked to a 100mm × 100mm × 1.6mm aluminum plate. Reverse leakage remains ≤500µA at 125°C, supporting reliable operation in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse line transients up to 600V without breakdown |
| IF(AV) | 8.0 A - Sustained DC output current capability at TC = +110°C |
| VF Max | 1.0 V @ 4A - Forward conduction loss directly impacts thermal rise and efficiency |
| IR Max | 5 µA @ 25°C - Low leakage preserves off-state blocking integrity in high-impedance circuits |
| IFSM | 170 A (8.3ms half-sine) - Handles cold-start inrush surges in transformer-coupled supplies |
| RθJC | 1.6 °C/W - Enables predictable thermal design when mounted on specified heatsink |
| CT per element | 55 pF @ 1MHz - Minimal capacitive coupling reduces EMI in low-frequency rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same 8A/600V rating, GBU package (smaller footprint, lower I²t = 90A²s) | Limited surge margin; less suitable for transformer-coupled inrush | Prefer for space-constrained PCBs where surge is controlled externally |
| KBU6K (Shindengen) | 6A average current, same 600V VRRM, KBU package (higher RθJC = 2.0°C/W) | Lower current capacity requires derating in 8A designs | Select only if load current consistently stays below 6A with margin |
Compared with GBU8K and KBU6K, the GBJ806 offers superior surge robustness (170A vs. 120A/100A) and lower thermal resistance-critical for high-reliability industrial power supplies where ambient temperature and inrush stress are uncontrolled.

FAQ
What is the maximum junction temperature for continuous operation?
The GBJ806 supports continuous operation from –55°C to +150°C junction temperature. At rated 8A average forward current, thermal design must ensure TJ does not exceed +150°C-achievable using the specified 100mm × 100mm × 1.6mm aluminum heatsink and maintaining RθJC at 1.6°C/W.
Is GBJ806 suitable for use in automotive applications?
GBJ806 is not AEC-Q101 qualified. While it meets RoHS and operates across –55°C to +150°C, Diodes explicitly states that automotive-grade variants require PPAP capability and IATF 16949 manufacturing-contact Diodes directly for qualified alternatives like the AEC-Q101-compliant GBJ806Q.
How does the GBJ package differ from GBU or KBU packages?
The GBJ package is larger than GBU and KBU, with standardized 30.0mm × 20.0mm footprint and #6 screw mounting provision. Its higher mass and optimized thermal path yield lower RθJC (1.6°C/W vs. 2.0°C/W for KBU), making it preferred for high-current, high-reliability applications where mechanical stability and heat dissipation are critical.
Can GBJ806 be used in place of GBJ804 or GBJ808?
Yes-GBJ806 shares identical package, pinout, thermal characteristics, and surge rating with other GBJ8xx devices. The only difference is VRRM: 600V (GBJ806) vs. 400V (GBJ804) or 800V (GBJ808). Substitution requires verifying that line transients and peak reverse voltage remain within the selected part's VRRM rating.
