It is rated for a repetitive off-state voltage of 1.8 kV and an average on-state current of 844 A, with an RMS on-state current of 1500 A. The device is built for industrial power conversion — think motor drives, welding equipment, DC traction supplies, and large UPS systems where a single high-current SCR handles the rectification or phase-control leg. The 14500 A non-repetitive surge current rating at 50 Hz gives it the headroom to survive short-circuit or inrush events without immediate failure, which is the kind of margin a design engineer budgets for when the load side has a capacitor bank or a motor starting transient. The maximum gate trigger voltage is 1.5 V, and the maximum gate trigger current is 250 mA. That is a fairly high gate drive requirement — a standard logic-level or optocoupler output will not fire this SCR directly. You need a gate driver stage, typically a pulse transformer or a dedicated SCR gate-drive module, that can source at least 250 mA peak into the gate-cathode junction. The maximum hold current is 300 mA, meaning once the SCR is latched, the anode current must drop below 300 mA for the device to commutate off. In a DC circuit with a resistive load, that is straightforward; in an inductive load, you need to ensure the commutation circuit can force the current below that threshold, or the SCR stays on until the next zero-crossing in an AC application. ## Mounting and thermal interface — the clamp-on package changes the assembly process The DO-200AB B-PUK is a ceramic-housed, studless package that clamps between two heatsink halves or a heatsink and a busbar. There are no screw terminals; the electrical and thermal connection is made through the clamping force. That means the assembly requires a calibrated clamp tool and a specified torque or pressure — the datasheet will give the clamping force range. The thermal pad or interface material must be chosen for the full 1500 A RMS current path, and the heatsink must be sized for the junction-to-case thermal resistance. This is not a part you socket or solder — it is a press-pack style device for bolted assemblies in high-power cabinets. ## Lifecycle and sourcing — active, but a specialist part That said, this is a high-power discrete with a specific package and mounting style — it is not a commodity part stocked in deep volume at every distributor.","metaTitle":"Infineon T830N16TOFXPSA1 SCR, 1.8 kV, 844 A, DO-200AB","metaDescription":"Infineon T830N16TOFXPSA1 single SCR rated 1.8 kV off-state, 844 A average on-state, 1500 A RMS.
