Our advantages

1. Universal GBU industry standard footprint, pin-to-pin compatible with mainstream rival rectifiers without PCB revision
2. 800V reverse voltage rating matches most global 110/220V AC power supply circuits
3. Excellent surge current endurance effectively prevents fuse breakdown caused by startup large current
4. Low forward voltage minimizes power dissipation, improves power supply efficiency and reduces operating temperature
5. UL certification supports export to North America, European and other international markets
6. 275°C high-temperature solder resistance adapts fully automated mass production soldering lines
7. UL94 V-0 flame retardant plastic shell reduces hidden safety hazards of high-load power devices
8. RoHS lead-free terminals satisfy international environmental protection regulations
9. Dual thermal resistance indexes for flexible thermal layout:
   • RθJA = 26.0°C/W (junction to ambient, no heatsink)
   • RθJC = 3.4°C/W (junction to case, with heatsink)
10. Integrated four-diode bridge structure saves PCB space compared to discrete diode rectifier schemes
