The through-hole mounting suits designs where vibration resistance and manual rework are priorities over board density. ## Lifecycle — officially obsolete Buyers should verify the remaining shelf stock and consider qualifying a pin-compatible alternative if the design allows.","metaTitle":"STFI34N65M5 N-Channel MOSFET, 650 V, 28 A, 110 mOhm Rds(on)","metaDescription":"STFI34N65M5 N-channel 650 V, 28 A MOSFET, 110 mOhm Rds(on) at 14 A.
