Product details

Rds(on) is 1.2 Ohm at 4 A, 10 V. Gate charge is 68 nC at 10 V.

Temperature range and package — fits industrial and automotive environments

The TO-220FP through-hole package mates with standard heatsink clips and is rated for 35 W dissipation at the case — derate above 25 °C per the datasheet curve. Input capacitance is 1370 pF at 25 V drain-source, a moderate Ciss that does not force an oversized gate resistor for EMI control.

The base product number STP9NK70 covers the family; the ZFP suffix identifies the full-pack TO-220 variant.
