Inductively Charged Electric Toothbrush Equipped with Z1SMA47 Zener Diode

This intelligent electric toothbrush is designed for convenience and efficiency, perfect for your travel needs. With extended battery life, you can enjoy hassle-free use wherever you go. Fully charged battery lasts minimum two weeks, enough for an entire holiday trip.

Its waterproof design provides protection against water splashes, a must in bathroom environments. A key for that important feature is the inductive charging system, consisting of a primary coil in the base and the secondary one in the toothbrush.

Diotec's Z1SMA47 zener diodes are installed in the charging base. The input circuit is as simple as clever: It is a capacitive power supply and an oscillator supplying the transmission coil. Part of the power supply is the Z1SMA47, a 1.5 W / 47 V Zener in a DO-214AC/SMA package. This device allows to meet the EU and US "Energy Star" requirement of less than 1 W of standby power. As such, you can keep the socket permanently connected to the mains, without the need to plug and unplug for every new charging cycle.
