Description
GBU608 is a through-hole full-wave bridge rectifier from Slkor’s GBU series. It integrates four high-performance rectifier diodes into a standard GBU molded plastic package to realize full-wave AC-to-DC rectification. This model is rated at 800V repetitive peak reverse voltage and 6A average rectified forward current. The component holds UL safety certification (File No.E230084) and fully complies with RoHS environmental standards. With strong surge current resistance and low forward voltage drop, it serves as a universal front-end rectification device for consumer adapters, switching power supplies, audio equipment and household appliances.
Features
- Standard GBU 4-pin through-hole package, perfectly suited for PCB wave soldering production
- VRRM repetitive peak reverse blocking voltage: 800V, fits global 220V AC input power supplies

- Excellent non-repetitive surge forward current capacity to withstand large power-on inrush pulses
- Low typical instantaneous forward voltage (VF=1.0V @ IF=3A) to reduce power loss and heat generation
- UL recognized safety component, meeting international electronic product safety standards
- High-temperature soldering resistance: withstand 275°C solder dipping for max 7 seconds per JESD 22-B106
- UL94 V-0 flame retardant molding compound improves overall equipment safety
- Tin-plated terminals, solderable in compliance with J-STD-002 and JESD22-B102 specifications
- Clear AC/DC polarity marks printed on the package body for easy wiring identification
- Wide junction and storage temperature range: -55°C ~ +150°C
- Complete thermal resistance parameters for accurate heatsink matching design
Our advantages
- Industry-standard GBU pinout, pin-to-pin compatible with mainstream alternative rectifiers without PCB redesign
- 800V high reverse voltage rating covers most universal AC power supply circuits without extra series diodes
- Outstanding surge withstand capability effectively avoids fuse burnout caused by startup instantaneous large current
- Low forward voltage drop cuts conduction loss, boosts power supply efficiency and lowers long-term operating temperature
- UL certification supports export sales to North America, Europe and other overseas markets
- 275°C high-temperature solder tolerance adapts to fully automatic wave soldering mass production lines
- UL94 V-0 flame retardant plastic shell eliminates fire risks for high-load power equipment
- RoHS lead-free terminals satisfy global environmental protection requirements for electronic products
- Dual thermal resistance indicators for flexible thermal layout design:
- RθJA = 26.0°C/W (junction to ambient, no heatsink)
- RθJC = 3.4°C/W (junction to case, with heatsink)
- Integrated four-diode bridge structure saves PCB space compared to discrete separate diode rectifier circuits
