• Adjustable speed drives
• Robotics
• Oceanographic equipment
• UPS systems
• Medical imaging apparatuses

Working Principle

GURB5H60HE3/45 works on the principle of avalanche breakdown. It operates by having a single element with a gate capacitance and gate resistance which allows for breakdown to occur. When a voltage is applied between the gate and the element, the breakdown voltage level is reached and current begins to flow through the element. This current is then limited by the gate capacitance and gate resistance in the device.

When avalanche breakdown occurs, the device is able to carry substantial inrush current levels and handle the harsh environment associated with industrial power supplies. The device is then able to block the reverse voltage up to 600 V.

Conclusion

GURB5H60HE3/45 belongs to the Diodes - Rectifiers - Single family of products and offers a variety of features and benefits. It is mainly used in industrial drives, uninterruptible power supplies, and automotive, industrial, and consumer applications. GURB5H60HE3/45 works on the principle of avalanche breakdown and operates by having a element with a gate capacitance and gate resistance which allows for breakdown to occur.
