FQA70N15 Description

Short technical summary and product information.

The FQA70N15 is an N-Channel enhancement mode power MOSFET produced using onsemi's proprietary planar stripe and DMOS technology. This advanced MOSFET technology is tailored to reduce on-state resistance and provide superior switching performance and high avalanche energy strength.

 

Key electrical specifications include a drain-source voltage of 150 V, continuous drain current of 70 A at 25°C (50 A at 100°C), and a maximum on-resistance of 28 mΩ at VGS = 10 V and ID = 35 A. The device features low gate charge (typical 135 nC, maximum 175 nC) and low reverse transfer capacitance (typical 135 pF). It is 100% avalanche tested with a single pulse avalanche energy rating of 1000 mJ.

 

The MOSFET is housed in a through-hole TO-3PN package (TO-3P-3 / SC-65-3) and is Pb-Free (lead-free) as per the datasheet. The operating junction temperature range is -55°C to 175°C. These devices are suitable for switched mode power supplies, audio amplifiers, DC motor control, and variable switching power applications.
