Diodes - Zener - Single

The SML4746HE3/61 is a single type Zener diode, which is a semiconductor device made up of an N-type and a P-type silicon material sandwiching a band gap to form a PN junction. This diode is often referred to as a Zener because of its ability to maintain a constant voltage across its leads. It works in reverse bias, with the current flowing from the Cathode to the Anode.

The SML4746HE3/61 is a Zener diode for special low voltage applications, with a maximum breakdown voltage of only 6.1V. It is lead (Pb) free and has an average rectified current rating of up to 100 mA, as well as a maximum forward voltage drop of 0.3V at 100 mA and 0.8V at 400 mA. It also features low noise, good reverse leakage and low temperature coefficient.

The main application of the SML4746HE3/61 is voltage regulation over a wide range of applications. This component acts as a voltage clamp to protect circuits and components from excessive voltage. It is used in order to maintain a constant output voltage, in a wide range of applications, from automotive electronics, to industrial control systems, to consumer electronics.

The working principle of the SML4746HE3/61 is that of a traditional Zener diode. It works in reverse bias, meaning that the voltage is applied in the reverse direction, from the cathode (negative terminal) to the anode (positive terminal). When the voltage exceeds the breakdown voltage of the diode, or the threshold voltage, current passes through to the anode (positive). This current is limited by the Zener impedance of the diode, and the voltage is clamped at the Zener voltage. This inhibits any excess voltage from passing through to the circuit, and thus prevents any damage.

The SML4746HE3/61 is an ideal low voltage Zener diode with a wide range of applications. It is used to regulate the flow of current and protect circuits from excessive voltage, as well as providing a constant output voltage. The device is lead (Pb) free, has a low noise operation and good reverse leakage. It is suitable for automotive electronics, industrial control systems, consumer electronics and many other applications.
