KP phase-control thyristors
KP1200A1400V
KP standard thyristors are manufactured using a fully diffused process and housed in disc-type ceramic packages. They support double-sided cooling to meet heat dissipation requirements at high power density. Main applications include phase-controlled rectification, AC voltage regulation, high-power motor drives and speed control, DC traction drives, industrial converters, grid-connected and stand-alone inversion, generator excitation, and power supplies for electrolysis, electroplating and charging. Select the gate trigger circuit and cooling conditions to match the on-state current and voltage class.

Questions before ordering
What should I include in an enquiry?
Provide the model, quantity and application, together with voltage, current waveform, operating frequency and cooling conditions. A drawing helps confirm mounting compatibility.
Can I select a replacement using only current and voltage?
No. Check switching and trigger requirements, surge duty, package dimensions, clamping or mounting requirements, and the complete thermal arrangement.
Which documents should I request?
Identify the model-specific datasheet, dimensional drawing, test records and any market-specific compliance evidence your project requires. Confirm their scope with the quotation.
