In Figure 2, a flyback diode was added in antiparallel with the solenoid. Instead of spiking to -300 V, the flyback diode only allows approximately -1.4 V of potential to be built up (-1.4 V is a combination of the forward bias of the 1N4007 diode (1.1 V) and the foot of wiring separating the diode and the solenoid [dubious – discuss]). The ...
It features common-cathode flyback diodes for switching inductive loads (such as servomotors). It can come in PDIP , SOIC , SOP or TSSOP packaging. [ 1 ] [ 2 ] In the same family are ULN2002A, ULN2004A, as well as ULQ2003A and ULQ2004A, designed for different logic input levels.
Flyback diode – Voltage-spike stopping diode across an inductor - a device to channel inductive spikes back through the coil producing them Voltage sag – Short-duration reduction in the voltage of an electric power distribution system

Switching losses happen in the transistor and diode when the voltage and the current overlap during the transitions between closed and open states. A schottky diode can be used to minimize the switching losses caused by the reverse recovery of a regular PN diode. [11] The switching losses are proportional to the switching frequency.
