Diotec Semiconductor AG

The Diotec GBI25J-LV is a 25 A, 600 V bridge rectifier optimized for low forward voltage under typical load conditions. At a forward current of 12.5 A, the forward voltage remains below 0.92 V per diode. With two diodes permanently in the current path, this reduction in V_F lowers total conduction losses by up to 20% compared with conventional bridge rectifiers — under nominal operating conditions, not only at peak load.

The device is rated for an average output current of 25 A at a case temperature of 80 °C, supporting high current density in compact power designs. Surge current capability reaches 325/360 A, providing comfortable margin against inrush events and transient overloads. Reverse leakage current is specified at below 5 µA, supporting efficiency and thermal stability across operating temperature ranges.

The GBI25J-LV is supplied in a GBI single-inline package with asymmetric pin pitch of 2x 7.5 mm and 10 mm. The package supports direct heatsink mounting, enabling efficient thermal coupling and predictable temperature control in high-power designs.

Typical applications include server and data center power supplies, telecommunications and base station equipment, network infrastructure and continuously operating industrial power systems, in which rectifier conduction losses accumulate with every mains cycle, directly affecting system efficiency and lifetime.
