Topband: Detuning Relay Flyback Diode

[Paul Christensen]

A single-component option with the benefits of the combo diode/Zener that Jim described is a “Transorb” device. The link below opens an application note that discusses various forms of coil transient suppression, beginning with passive, then single diode, a combo diode-Zener (mentioned by Jim and recommended by Schrack) and then concludes with the “Transil,” ST’s trade name for their transorb device.
