Our advantages

1. Universal GBU standard through-hole outline, pin dimensions fully compatible with industry mainstream substitutes, no PCB redesign required
2. High 1000V reverse voltage rating adapts to high-input AC power supply circuits without extra series diodes
3. Strong 175A surge capacity effectively withstands inrush current during power-on, reducing fuse failure risk
4. Low VF minimizes power loss, improves power supply efficiency and lowers shell operating temperature
5. UL safety certification supports export to North American, European and other overseas markets
6. 275°C high-temperature solder resistance fits automated mass production wave soldering lines
7. UL94 V-0 flame retardant plastic shell eliminates fire hazards for high-load power equipment
8. Low reverse leakage reduces standby power consumption of battery chargers and adapters
9. Stable glass passivation chip technology extends service life for long-running household appliances
10. Compact flat GBU package saves vertical PCB space compared to bulky separate diode assemblies
