Additional Details

The 2SJ248 is designed to deliver high-fidelity audio with minimal distortion. Its low noise characteristics ensure a clean audio signal, while the high input impedance prevents loading of the signal source. The excellent linearity ensures accurate amplification across the audio frequency range. The high power gain allows for efficient amplification of audio signals. The fast switching speed enables the MOSFET to handle high-frequency audio signals. The TO-3P package provides good thermal conductivity and allows for easy mounting and heatsinking. Consult the datasheet for specific electrical characteristics, such as gate threshold voltage, on-resistance, and transconductance. Often used in complementary pairs with N-channel MOSFETs for push-pull audio amplifier designs.
