Single FETs, MOSFETs Procurement Notes

Verify the specific datasheet revision when sourcing, as Littelfuse acquired IXYS components. Confirm that the TO-247HV package dimensions match your PCB footprint requirements. Ensure thermal management solutions are adequate for the 80 ohm on-resistance to maintain junction temperatures within the specified -55°C to +150°C operating range during high-voltage operation.

Single FETs, MOSFETs Selection Notes

Select this component for designs requiring extreme voltage isolation rather than high current switching. The 1 A current limit and high on-resistance make it unsuitable for standard low-voltage power conversion. It is specifically optimized for blocking high voltages in pulsed or static high-voltage environments where standard MOSFETs would fail.

Single FETs, MOSFETs Part Context

This part belongs to the IXYS high-voltage MOSFET family, now under Littelfuse. These devices utilize specialized trench technology to achieve high breakdown voltages while maintaining manageable gate charge characteristics. The TO-247HV package provides enhanced creepage and clearance distances compared to standard packages, supporting safe operation at 4.5 kV.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes must match the 4500 V rating and TO-247HV package. Verify pinout compatibility. Generic replacements may lack the specific avalanche ruggedness required for capacitor discharge loads.
