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.

3-to-8 line decoder/demultiplexer The 74HC238; 74HCT238 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1 and E2 and E3). Every output will be LOW unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four '238 ICs and one inverter. The '238 can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. • Wide supply voltage range from 2.0 to 6.0 V • CMOS low power dissipation • High noise immunity • Demultiplexing capability • Multiple input enable for easy expansion • Ideal for memory chip select decoding • Active HIGH mutually exclusive outputs • Input levels: • For 74HC238: CMOS level • For 74HCT238: TTL level • Complies with JEDEC standards • JESD8C (2.7 V to 3.6 V) • JESD7A (2.0 V to 6.0 V) • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B • ESD protection: • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V • Multiple package options • Specified from -40 °C to +85 °C and from -40 °C to +125 °C #74HC238N #74HCSeries #CMOSLogic #DecoderIC #Demultiplexer #DigitalLogic #AddressDecoder #ChipSelect #LogicGate #IntegratedCircuit #ElectronicsDesign #EmbeddedSystems
