For existing BOM lines, secure enough stock to cover the remaining production run before channel inventory dries up. The 600 V drain-source voltage (Vdss) places this MOSFET in the high-voltage class for off-line power supplies, PFC boost stages, and flyback converters. The 88 mOhm maximum Rds(on) at 17 A with 10 V gate drive defines the conduction loss; note the 10 V drive requirement — this part is not suited for 5 V logic-level gate drive without a driver stage. Gate charge of 57 nC at 10 V is moderate for a 600 V device, keeping switching losses manageable with standard gate-driver ICs. ## Full-pack TO-262 — no insulating hardware needed The TO-262-3 Full Pack (I2PAKFP, supplier device package I2PAKFP TO-281) has an isolated metal tab, so no insulating pad or shoulder washer is required between the device and the heatsink. This simplifies assembly and improves thermal contact. Through-hole mounting suits high-vibration environments or manual rework lines where surface-mount parts are less practical. The 150°C maximum junction allows higher power dissipation in hot environments, but the 40 W package limit still governs.","metaTitle":"STFI40N60M2 N-Channel MOSFET, 600V, 34A, MDmesh II Plus","metaDescription":"STMicroelectronics STFI40N60M2 N-channel 600V 34A MOSFET in TO-262 full-pack. 88mOhm Rds(on), 57nC gate charge.
