IRFF230

The IRFF230 is a 200V N-channel power MOSFET manufactured by Infineon Technologies, designed for high-reliability switching applications in demanding environments. Housed in a hermetic TO-39 (TO-205AF) metal can package, this device provides inherent resistance to moisture and contamination, enabling stable operation across wide temperature ranges. It features avalanche ruggedness and 100% screening typical of Infineon’s HiRel portfolio, with low gate charge and threshold voltage optimized for efficient drive in high-frequency power conversion stages.

Typical deployments include DC-DC converters and load switching in satellite power buses, actuator drive circuits in aerospace flight controls, and high-temperature downhole instrumentation where board-level reliability is critical. For procurement, the IRFF230 often falls under long lead-time or end-of-life considerations given its niche hermetic packaging; engineers evaluating this MOSFET should confirm active production status and consider available military-grade variants (such as JANTX or JANTXV) if source control drawings require qualified components. Sourcing through authorized distribution ensures traceability and protection against counterfeit devices in defense and space supply chains.
