Diodes can be subdivided into two main classes: Rectifier diodes (standard recovery) and fast diodes. Rectifier diodes are generally used for conversion of AC (alternating current) to DC (direct current). While optimized for low conduction losses, Rectifier diodes withstand only moderate dynamic stress in transition from conducting to the blocking state.
LEM's new Unique, IP68, ruggedized outdoor flexible split-core AC current sensor implementing high accuracy Rogowski Coil technology.
Ethics programs aim to prevent and detect criminal conduct, reinforcing compliance with legal requirements. They also foster an organizational culture in which employees feel empowered to ‘do the right thing,’ even when laws and regulations don’t provide clear guidance.
Mitsubishi Electric offers general rectifying diode modules that rectify commercial frequencies and high frequency diode modules for freewheel diodes in inverter circuits and for high-speed switching on a surge voltage absorbing circuit (snubber). The main switching devices of an inverter have changed from bipolar transistors to high-speed MOS gate devices, such as IGBT. The requirements of radio noise regulations have also increased the importance of not just reverse recovery characteristics, but also software recovery characteristics.

Dynex Semiconductor produces a small range of thyristors for very fast turn-on based on its GTO structures. To support our customers, we design and produce the complete switch assemblies, including semiconductor devices, driving units, clamping, cooling, and testing.
Smart Electronic Battery Sensors LEM, the current measurements expert, brings its experience and know-how to provide advanced battery monitoring solutions for 12/24V battery storage systems based on lead-acid battery technology.
ABB’s IGBT power modules are available from 1700 to 6500 volt as single IGBT, dual / phase-leg IGBT, chopper and dual diode modules. The high-power HiPak IGBT modules feature low losses combined with soft-switching performance and record-breaking Safe Operating Area (SOA). The newly introduced 62Pak fast switching medium-power IGBT modules feature lowest switching losses, full 175 °C operation with full square SOA and standard package allowing drop-in replacement.
IPM's (Intelligent Power Modules) are high-performance module that mounts a dedicated drive circuit for drawing greater performance from an IGBT chip, and it provides a custom IC for executing self-protection functions (short circuit, supply under voltage, and over temperature).
Gate Drivers are designed for triggering large Gate-Turn-Off Thyristors (GTO) featuring gate-turn-off currents up to 3000 Amps and off-state voltages up to 4500 volts. The control signal, transmitted via fiber optics, controls the output valve of the gate driver. A feedback signal, also transmitted via fiber optics, is used to check that the gate driver and GTO are operating properly. This GTO Gate Driver was developed for use in traction systems and is currently being used successfully by numerous customers.
