Mosfet Switch Boards
Explore our range of MOSFET Switch Boards, engineered to provide total isolation between the signal and power source for the MOSFET driver, and the circuit side where the MOSFET is connected. Designed around advanced high-speed gate drivers, these boards deliver exceptional switching performance, precision, and reliability. Our lineup includes versions for multiple MOSFET package and socket types — from standard TO-247 screw-terminal boards to TO-247-4 Kelvin-source sockets and TO-263-7 surface-mount platforms — enabling effortless device swapping, rapid evaluation, and support for extreme high-voltage experimentation.
We also offer bidirectional MOSFET switch boards for full AC current blocking using a back-to-back device configuration, eliminating the body-diode limitation found in standard MOSFETs. This makes them ideal for resonance systems, tank circuits, AC switching, and applications where current reverses direction. Our conventional switch boards include a BNC input for seamless integration with laboratory signal sources and are suitable for both high-side and low-side operation, making them a powerful platform for advanced pulsed-power, high-frequency, and high-voltage applications.
For voltages beyond the capability of a single MOSFET, our Stackable MOSFET Switch system allows up to five independently driven MOSFET stages to be connected in series and synchronized through fibre-optic triggering. Using suitable 3300 V MOSFETs, a five-stage stack can operate at approximately 15 kV while maintaining extremely fast switching performance. Each stage features its own isolated gate drive and power domain, providing a flexible solution for nanosecond pulse generation, capacitor discharge, plasma experiments, and other demanding high-voltage switching applications.
