STW30NF20

STW30NF20 Description

The STW30NF20 from STMicroelectronics is an N-channel 200V, 30A power MOSFET housed in a TO-247-3 package, designed for high-efficiency power switching applications. Part of the STripFET™ series, it leverages advanced MOSFET (Metal Oxide) technology to deliver low on-resistance (75mOhm @ 15A, 10V) and high power dissipation (125W (Tc)). With a gate charge (Qg) of 38 nC @ 10V and input capacitance (Ciss) of 1597 pF @ 25V, it ensures fast switching performance, reducing losses in high-frequency circuits. Though marked Obsolete, it remains a robust choice for legacy designs requiring reliability under high-voltage conditions.
