FQA34N20 Description

Short technical summary and product information.

The FQA34N20 is a N-Channel power MOSFET manufactured by On Semiconductor. It operates with a maximum drain-source voltage of 200V and can continuously conduct 34A at a case temperature of 25°C. The device features a low on-resistance of 75mOhm maximum at 17A drain current and 10V gate voltage. It is designed for through-hole mounting in TO-3P package (also known as SC-65-3). The MOSFET offers a maximum gate charge of 78nC at 10V, making it suitable for switching applications. With a maximum power dissipation of 210W and operating junction temperature range from -55°C to 150°C, it can handle high-power designs. The input capacitance is 3100pF at 25V drain-source voltage. The gate threshold voltage is 5V maximum at 250µA. The device is listed as RoHS3 compliant, with an MSL rating of 1 (unlimited) and REACH unaffected status.
