KK fast thyristors
KK600A2500V
KK fast thyristors are manufactured using a fully diffused process and housed in disc-type ceramic packages. They support double-sided cooling and feature fast switching, short turn-off time and low high-frequency losses. Main applications include medium- and high-frequency inversion, choppers, pulsed power supplies, induction heating, electric welding machines, frequency converters, and AC and DC motor speed control. Select the gate trigger circuit and cooling conditions to match the operating frequency, turn-off time, 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.
