DZ是稳压管的电器编号，是和1N4148和相近的，其实1N4148就是一个0.6V的稳压管，下面是稳压管上的编号对应的稳压值，有些小的稳压管也会在管体上直接标稳压电压，如5V6就是5.6V的稳压管。
经常看到很多板子上有M记的铁壳封装的稳压管，都是以美标的1N系列型号标识的，没有具体的电压值，翻手册查了以下3V至51V的型号与电压的对照值，3V到51V 1W稳压管型号对照表1N47273V01N4728 3V31N4729 3V61N4730 3V91N4731 4V31N4732 4V71N4733 5V11N4734 5V61N4735 6V21N4736 6V81N4737 7V51N4738 8V21N4739 9V11N4740 10V1N4741 11V1N4742 12V1N4743 13V1N4744 15V1N4745 16V1N4746 18V1N4747 20V1N4748 22V1N4749 24V1N4750 27V1N4751 30V1N4752 33V1N4753 36V1N4754 39V1N4755 43V1N4756 47V1N4757 51V1N4728A 3.31N4729A 3.61N4730A 3.91N4731A 4.31N4732A 4.71N4733A 5.11N4734A 5.61N4735A 6.21N4736A 6.81N4737A 7.51N4738A 8.21N4739A 9.11N4740A 101N4741A 111N4742A 121N4743A 131N4744A 15摩托罗拉IN47系列1W稳压管IN4728 3.3vIN4729 3.6vIN4730 3.9vIN4731 4.3IN4732 4.7IN4733 5.1IN4734 5.6IN4735 6.2IN4736 6.8IN4737 7.5IN4738 8.2IN4739 9.1IN4740 10IN4741 11IN4742 12IN4743 13IN4744 15IN4745 16IN4746 18IN4747 20IN4748 22IN4749 24IN4750 27IN4751 30IN4752 33IN4753 34IN4754 35IN4755 36IN4756 47摩托罗拉IN52系列 0.5w精密稳压管IN5226 3.3vIN5227 3.6vIN5228 3.9vIN5229 4.3vIN5230 4.7vIN5231 5.1IN5232 5.6IN5233 6IN5234 6.2IN5235 6.8IN5236 7.5IN5237 8.2IN5238 8.7IN5239 9.1IN5240 10IN5241 11IN5242 12IN5243 13IN5244 14IN5245 15IN5246 16IN5247 17IN5248 18IN5249 19IN5250 20IN5251 22IN5252 24IN5253 25IN5254 27IN5255 28IN5256 30IN5257 33IN5730 5.6IN5731 6.2IN5732 6.8IN5733 7.5IN5734 8.2IN5735 9.1IN5736 10IN5737 11IN5738 12IN5740 15IN5741 16IN5742 18IN5743 20IN5744 22IN5745 24IN5746 27IN5747 30IN5748 33IN5749 36IN5750 39IN5985 2.4IN5986 2.7IN5987 3IN5988 3.3IN5989 3.6IN5990 3.9IN5991 4.3IN5992 4.7IN5993 5.1IN5994 5.6IN5995 6.2IN5996 6.8IN5997 7.5IN5998 8.2IN5999 9.1IN6000 10IN6001 11IN6002 12IN6003 13IN6004 15IN6005 16IN6006 18IN6007 20IN6008 22贴片型SOD-123穏压二极管型号规格标示法Marking Code SINLOON SMD SOD-123 Zener Diode型号电压代码标示Type /Voltage / Marking CodeHZD5221B 2.4V Z21HZD5222B 2.5V Z22HZD5223B 2.7V Z23HZD5224B 2.8V Z24HZD5225B 3.0V Z25HZD5226B 3.3V Z26HZD5227B 3.6V Z27HZD5228B 3.9V Z28HZD5229B 4.3V Z29HZD5230B 4.7V Z30HZD5231B 5.1V Z31HZD5232B 5.6V Z32HZD5233B 6.0V Z33HZD5234B 6.2V Z34HZD5235B 6.8V Z35HZD5236B 7.5V Z36HZD5237B 8.2V Z37HZD5238B 8.7V Z38HZD5239B 9.1V Z39HZD5240B 10V Z40HZD5241B 11V Z41HZD5242B 12V Z42HZD5243B 13V Z43HZD5244B 14V Z44HZD5245B 15V Z45常用肖特基二极管型号:常用肖特基二极管型号:常用的有引线式肖特基二极管有D80-004、B82-004、MBR1545、MBR2535等型号，各管的主要参数见表4-43。
