Is VBE always 0.7 V?For an unbiased transistor, considering only the BE junction which is a pn junction diode, 0.7V is the potential barrier. In an npn transistor base is positive(p) and emitter is negative(n). So the potential barrier vbe=0.7V. But in a pnp transistor the base is negative(n) and emitter is positive(p) so the vbe=-0.7V.
