N-Channel 30 V 161A (Tc) 140W (Tc) Surface Mount TO-252AA (DPAK) The IRLR7843TRPBF is an N-channel power MOSFET built on Infineon's HEXFET technology platform, originally developed by International Rectifier. It is designed as a low-voltage, high-current switching device intended for applications where minimizing conduction loss and maximizing efficiency are primary design goals. The part is particularly well suited to synchronous switching topologies, where pairs or arrays of MOSFETs alternately conduct to regulate power flow with minimal energy dissipation. This device targets high-density power conversion applications where board space is limited but current demands are substantial, such as notebook computer power delivery, point-of-load converters used in servers, and advanced telecom and datacom equipment. It is commonly found supporting synchronous buck converter stages that step down a higher input rail to a lower output voltage suitable for powering processors, memory, and other low-voltage digital logic. Its low on-resistance characteristic allows it to carry significant current while generating comparatively little resistive heating, which is essential in compact enclosures with constrained thermal budgets. The transistor is fabricated using a refined trench gate process that improves upon earlier HEXFET generations, offering reduced gate charge and lower switching losses alongside its low conduction resistance. This combination makes it effective in both the high-side and low-side positions of a synchronous switching cell, where fast, clean transitions reduce overlap losses and improve overall converter efficiency. The device also offers well-characterized avalanche energy ratings, giving designers confidence in its ruggedness when exposed to transient overvoltage events that can occur during switching, and it presents a very low gate impedance, allowing it to be driven efficiently by standard gate driver circuitry. Mechanically, the part is housed in a surface-mount power package with an exposed tab for enhanced thermal conduction to the host PCB, allowing heat generated during operation to be efficiently transferred away from the silicon die. This package style is widely used in power-dense designs where through-hole packages would be impractical. The device is supplied in a tape-and-reel format suitable for automated assembly and is compliant with RoHS material restrictions, reflecting current environmental and regulatory standards for electronic components.

N-Channel 4700 V 2A (Tc) 220W (Tc) Through Hole ISOPLUSi5-Pak™ Full picture confirmed from IXYS/Littelfuse datasheet sources — N-channel MOSFET, unipolar, ultra-high voltage class, housed in the ISOPLUS i5-Pak package. Here's the complete spec. digikey Engineering Specification — IXTL2N470 Manufacturer: IXYS Corporation (now Littelfuse) Device Family: Very High Voltage N-Channel Power MOSFET Series General Description The IXTL2N470 is an N-channel enhancement mode high voltage power MOSFET manufactured by IXYS Corporation, now part of Littelfuse. It represents one of the highest drain-to-source voltage ratings available in the silicon MOSFET product category, placing it in a specialized class of ultra-high-voltage switching devices intended for applications where voltage stress levels far exceed what conventional power MOSFETs can safely sustain. This makes it applicable to a narrow but technically demanding set of power electronics applications, including pulsed power systems, high-voltage DC-DC converters, industrial plasma generation equipment, high-energy capacitor discharge circuits, medical imaging power supplies, radar transmitter stages, and other systems that operate at voltage levels substantially higher than those encountered in standard power conversion equipment. digikey The device is built on enhancement-mode MOSFET technology, meaning it remains in a non-conducting off state when no gate voltage is applied and is switched into conduction by applying a positive gate-to-source voltage above its threshold level. This normally-off characteristic is preferred in high-voltage switching applications because it ensures that the device does not conduct inadvertently in the absence of a gate drive signal, which is particularly important in high-voltage circuits where uncontrolled conduction could result in catastrophic circuit damage or safety hazards. The MOSFET's gate is driven by standard gate driver circuitry, and the device incorporates an integrated gate resistance that limits the rate of current change through the gate path, helping to control turn-on and turn-off transition speed and reduce electromagnetic interference generated by very fast switching edges at these extreme voltage levels. As a silicon planar MOSFET designed for this voltage class, the IXTL2N470 operates with a relatively modest continuous drain current capability compared to lower-voltage devices of similar die size, which is an inherent characteristic of the high-voltage MOSFET device physics that requires thicker drift regions to sustain high blocking voltages, increasing on-resistance and limiting current density. This tradeoff is well understood in ultra-high-voltage MOSFET design, and the device is primarily optimized for voltage-blocking capability and switching behavior rather than high current throughput, making it most appropriate for series-connected switch stacks, resonant converter topologies, or pulsed applications where peak current is brief and average current is modest. The device is housed in IXYS's proprietary ISOPLUS i5-Pak package, a surface-mount-compatible power package that integrates an electrically isolated mounting surface directly within the package construction. This isolation feature allows the device to be mounted directly to a grounded metal heatsink or chassis surface without requiring a separate insulating pad or bushing between the device and the heatsink, simplifying the thermal management assembly process and reducing the total thermal resistance between the silicon die and the heatsink. The package is through-hole compatible for lead attachment to the PCB, while the thermal interface is designed for direct chassis or heatsink contact, making it well suited to compact power module and equipment panel-mount designs.
