我正在尝试为 TL431 创建一个简化的符号，它有一个齐纳二极管在中心和三个引脚，即阴极、阳极和参考。
到目前为止，我尝试使用 circuitikz 的 box 功能。但是，它不允许我在齐纳二极管（或普通二极管）周围放置一个盒子。我还尝试使用 /tikz/circuitikz/bipoles/length=0.5cm 缩小二极管并使用 box 选项，但仍然没有结果：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[siunitx,fetbodydiode,smartlabels]{circuitikz}
\usetikzlibrary{positioning}
\begin{document}
\begin{figure}
\centering
\begin{circuitikz}[lbl/.style = {label={[label distance=4mm]above right:#1}}] % this line defines a new style to alter the distance of labels, mosfets due to diode and transformer label
\draw
(0,0) node[mixer,box,anchor=east] (m) {}
to[/tikz/circuitikz/bipoles/length=0.5cm,Do,box,>,-o] ++(2.5,0)
(m.west) node[inputarrow] {} to[short,-o]
++(-0.8,0)
(m.south) node[inputarrow,rotate=90] {} --
++(0,-0.7) node[/tikz/circuitikz/bipoles/length=0.5cm,Do,box,anchor=north] {}
;
\end{circuitikz}
\caption[Ersatzschaltbild]{Ersatzschaltbild}
\label{fig:ersatzschaltbild}
\end{figure}
\end{document}
除了盒子之外，作为替代方案，我可以使用 circuitikz 中包含的常规齐纳二极管并为其添加第三个参考引脚吗？我该如何实现？
谢谢 ：）
/EDIT 这是我目前的结果。请随意使用。感谢你的帮助。

只要没有未包含在某些包中的元素，例如 circuitikz，您总是拥有旧的舒适的蛮力，您可以定义一个对象，就像您在某个电路 CAD 程序中创建其原理图一样，您可以命名引脚，以便以后可以使用标识符连接它们，这里的代码我希望会很有用。

如果您只想连接到盒子，您可以使用以下命令。
虽然此二极管具有形状名称fullsdiodeshape，但它需要某种参数，因此只能使用 to[] 来绘制
