Zener diode is mainly composed of metal electrode, oxide insulation layer and semiconductor material, and its working principle mainly depends on the reverse breakdown state of PN junction. The reverse voltage tolerance of Zener diodes is usually between tens of volts and hundreds of volts, and has excellent reverse voltage tolerance. Zener diode also has a specific breakdown voltage, when the reverse voltage reaches this value, the diode begins to enter the breakdown state, the current increases sharply, but the voltage remains constant.

The characteristics of Zener diode make it play a great role in the electronic components, but the overshoot and noise phenomenon in the application process will affect the stability and reliability of the circuit. In order to improve the application experience, Yisheng Electronics has optimized its existing Zener diode portfolio to eliminate adverse effects.

The new 50 µA Zener series diodes are available in B-selection (Vz±2%) with Vz ranges from 1.8V to 51V and are available in standard and automotive versions. In the past, many Zener diodes would cause application failures at high voltages, but the new 50 µA device family from Yisin provides full Zener functionality even at high voltages (up to 75 V), effectively avoiding noise and overshoot.

These devices are available in small packages, including SOT23, SOD323, SOD523, and SOD123FL, as well as DFN1006BD-2 and DFN1006-2 without side wettable pads (SWF). There are also significant advantages to having SWF included, including highly reliable automated optical inspection (AOI) of solder joint quality and enhanced solder joint robustness, which enhances the combination with the PCB compared to devices without SWF.

Optimized Zener diodes are ideal for automotive applications, such as on-board chargers for electric vehicles (EVs); And a wide range of industrial and consumer applications, such as universal computing units, battery management systems, device chargers, and smartwatches.
