2N5457.. – ONSEMI

The Onsemi 2N5457 is a N-Channel Junction Field Effect Transistor (JFET) designed for low-noise amplifier and switching applications. Its key advantage lies in its high transconductance and low input capacitance, facilitating excellent gain and bandwidth performance in sensitive analog circuits. This device offers a maximum drain-source voltage rating of 25V, and a continuous drain current rating of 50mA. Housed in a through-hole TO-92 package, the 2N5457 is easily integrated into breadboard prototypes and through-hole PCBs. It operates effectively within a temperature range of –55°C to 150°C, making it suitable for a variety of environments. Common use cases include impedance matching networks, preamplifiers for audio equipment, and high-input impedance buffer stages where minimal loading is crucial.
