        Features:

        • The TT430N22KOF contains two pressure-contact thyristors in a 60 mm Power Block housing.
        • Its SCR/SCR topology provides a controlled bidirectional current path for phase-control circuits.
        • An electrically isolated copper baseplate transfers heat toward the mounting heatsink.
        The two controlled arms share a compact assembly with separate main-power and gate connections.

        Case temperature, mounting pressure, and heatsink contact jointly define the usable current boundary.

        The KOF version is specified with a 1,000 V/µs critical off-state voltage-rise rating.

        Infineon TT430N22KOF Phase Control Thyristor Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        How the two controlled paths are arranged

        • Semiconductor Pair: Two silicon-controlled rectifiers form the TT phase-control circuit.
        • Pressure Contacts: Mechanical pressure provides the internal electrical and thermal contact.
        • Main Terminals: Three M10 power terminals expose the two-device current path.
        • Gate Connections: Separate 2.8×0.8 mm control tabs drive the individual thyristors.

        From silicon junctions to the heatsink

        • Baseplate: The electrically isolated copper base transfers losses out of the module.
        • Case Boundary: The 430 A current reference assumes an 85 °C case temperature.
        • Thermal Resistance: Each arm has a defined junction-to-case resistance under 180° sine conduction.
        • Optional TIM: Selected package versions can use factory-applied thermal interface material.

        Assembly details that preserve contact pressure

        • Heatsink Fasteners: Mechanical connections use a 6 Nm torque with ±15% tolerance.
        • Power Terminals: The M10 electrical connections require 12 Nm with ±10% tolerance.
        • Screw Depth: The drawing limits terminal screw engagement to 18 mm.
        • Creepage: A 19 mm creepage distance supports the module insulation boundary.

        Documented phase-control circuit roles

        • Motor Starting: Soft starters use controlled conduction to manage the applied motor voltage.
        • Drive and UPS Rectification: The module is listed for drive rectifiers and uninterruptible-power rectifiers.
        • Protection Paths: Crowbar and bypass functions use the high-current thyristor pair.
        • Power Conversion: Power controllers, battery chargers, and static switches are included in the documented uses.
        Description
        Infineon TT430N22KOF is a 60 mm Power Block phase-control module containing two silicon-controlled rectifiers. Its series-connected SCR/SCR topology provides a bidirectional controlled power path for high-current AC conversion.

        Pressure-contact elements inside TT430N22KOF transfer current through the main terminals to an electrically isolated copper baseplate assembly. The isolated base separates the power circuit from the heatsink while the defined creepage path and insulation-test rating establish the electrical boundary.

        Thermal design governs how TT430N22KOF reaches its 430 A average on-state rating at an 85 °C case temperature. The module fastens to the heatsink at 6 Nm, its M10 power terminals use 12 Nm, and the base interface must maintain the specified case-to-heatsink thermal path.

        Official application categories for TT430N22KOF include soft starters, drive rectifiers, crowbar circuits, power controllers, UPS rectifiers, battery chargers, static switches, and bypass switches. Each circuit must remain inside the module's 2200 V blocking, surge-current, junction-temperature, and commutation limits.

        Technical notes
        Infineon TT430N22KOF is the base product designation for a 2200 V SCR/SCR Power Block. Confirm the complete OPN because the recommended XPSA1 package and discontinued HPSA2 package do not share the same status.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Which complete OPN should be checked when ordering TT430N22KOF?
        Infineon TT430N22KOF has multiple OPNs: TT430N22KOFXPSA1 is the recommended active package, while TT430N22KOFHPSA2 is discontinued, so match the full label rather than only the base designation.
        Why is the 430 A rating of TT430N22KOF tied to case temperature?
        The average on-state current for Infineon TT430N22KOF is 430 A only at an 85 °C case temperature; heatsink selection and interface quality must keep the case within that condition.
        Can the 14,000 A surge figure for TT430N22KOF be used at maximum junction temperature?
        No. Infineon TT430N22KOF is rated for 14,000 A at 25 °C junction temperature and 12,000 A at maximum junction temperature for the specified 10 ms surge.
        Which torque values protect TT430N22KOF during assembly?
        For Infineon TT430N22KOF, tighten the mechanical heatsink connections to 6 Nm within ±15% and the M10 electrical terminals to 12 Nm within ±10%.
        Does the baseplate of TT430N22KOF electrically isolate the heatsink?
        Yes. Infineon TT430N22KOF uses an electrically isolated copper baseplate with basic insulation, while the assembly must still preserve the specified creepage and grounding design.
        What circuit roles are explicitly documented for TT430N22KOF?
        Infineon TT430N22KOF is documented for soft starters, drive rectifiers, crowbars, power controllers, UPS rectifiers, battery chargers, static switches, and bypass switches.
