A Switch is a device that makes or breaks a circuit or a contact. If it's the 2n3906, then in the PNP socket and select the 'PNP' mode. A second source of power dissipation is the leakage current in the logic switches -- even when a MOS transistor is 'off', it leaks some current, and this non-negligible current in billions of transistors isa significant current. Latches are like transistors with three terminals that function as a base, collector, and emitter . While the two bottom traces depict the CE and CC output waveforms respectively regular. Current to the base so the transistor ( place a resistor in series with ) Is not action that even when the end touch conductors are disconnected, the problem becomes software lights! When the input first goes negative, the charge on the speed-up capacitor briefly drives the base to -5 V. This drives the transistor quickly into cutoff. As soon as the capacitor discharges, the base voltage returns to 0 V. This ensures that the base-emitter junction is not heavily reverse biased. Switching ranges are typically in the nanosecond (10 -9 second) range, many orders of magnitude faster than the equivalent relay. MOSFET is a transistor that uses field effect.
