High temperature discrete thyristor and photovolatic gate driver

IXYS High Temperature Discrete Thyristors by GD Rectifiers

CPC1596 – 570V Load-Biased Opto-Gate Driver

IXYS’ photovoltaic (PV) Gate Drivers simplify SSR-design by eliminating the need for auxiliary power supplies. Due to output currents in μA-range, they get slower with larger gate charges of external MOSFETs, making it difficult to fulfil demanding application requirements.
