Either way, it very impor­tant to remem­ber that a Zen­er diode should always be used along with a Zen­er resis­tor.A Zen­er resis­tor is noth­ing but an ordi­nary resis­tor which is used for cur­rent lim­it­ing pur­pose. This resis­tor decides (lim­its) the amount of cur­rent that can flow through the Zen­er diode or through the load con­nect­ed to Zen­er diode; this was the Zen­er diode is pro­tect­ed from high cur­rent. If this resis­tor is not used the diode will be dam­aged due to high cur­rent. A sim­ple Zen­er diode cir­cuit is shown below.Applications of 1N4732A Zener DiodeUsed in Volt­age pro­tec­tion cir­cuitsCan be used as low cur­rent volt­age reg­u­la­torInput volt­age pro­tec­tion for Micro­con­trollers or oth­er IC’sVolt­age sta­bi­liz­ing cir­cuits
