Vishay GBU4B-E3/51 bridge rectifier is a high-performance single-phase semiconductor device designed for full-wave rectification in electronic power conversion systems. It features a 4-pin single configuration housed in a glass passivated junction SIL PCB mounting package, making it suitable for through-hole installation on printed circuit boards.
This bridge rectifier supports a peak reverse repetitive voltage (Vrrm) of 100 V and can handle peak forward surge currents (Ifsm) up to 150 A, ensuring robust operation in power-intensive applications. The typical forward current (If) rating is 4 A, with a peak forward voltage drop (Vf) of approximately 1 V, optimizing efficiency by reducing conduction losses.
The device functions reliably over a wide temperature range from -55°C minimum to 150°C maximum operating temperature. The low peak reverse current of 5 μA reduces leakage current, improving overall circuit performance. Its compact SIL GBU package offers dimensions of 22.3 mm length, 18.8 mm height, and 3.56 mm width, enabling space-efficient PCB layouts.
Vishay’s GBU4 series bridge rectifiers provide high surge current capability and excellent case dielectric strength of 1500 Vrms, making them well suited for industrial, electronics manufacturing, HVAC, and power supply applications. These rectifiers convert alternating current inputs into direct current output with consistent polarity, suitable for various industrial and laboratory power electronics.
Through-hole SIL PCB mounting simplifies installation and replacement. Glass passivated junction ensures stable, long-term performance. High surge current capacity supports transient load conditions. Compact dimensions support dense circuit board design.
Reliable operation at high temperatures enhances durability. Efficient power rectification with low forward voltage drop. Minimal reverse leakage current improves efficiency. High dielectric strength provides safety and insulation.
Applicable in industrial machines, power connectors, and electronic components. Manufactured according to Vishay quality standards for consistency and reliability.
