2N5457 is a general-purpose N-channel Junction Field Effect Transistor with Drain and Source interchangeable feature. It operates in depletion-mode and requires reverse biasing to turn off. Because depletion types MOSFETs act like a normally closed switch. It has high (AC and DC) input impedance, contrary to other MOSFETs.  It is a CMOS technology device used … Read more
