transistor not showing

Question

I am using circuit tikz to draw a diode in series with a transistor using the following:

\begin{figure}[h!]
\centering
\begin{circuitikz}[american, line width=0.3, line cap=round, line join=round]
    \ctikzset{diodes/scale=0.6}
    \draw (0,0) to[D] (2,0) to[nigbt] (4,0);
\end{circuitikz}
\end{figure} 

I don't get why the transistor is not drawn?

Answer 1

The path-style transistors must be specified by adding a T to the name. So, try with

... to[Tnigbt] ...

Answer 2

Symbol for transistor is not dipol, but is defined as node:

\documentclass[margin=3mm]{standalone}
\usepackage{circuitikz}

\begin{document}
\begin{circuitikz}[american, line width=0.3, line cap=round, line join=round]
    \ctikzset{diodes/scale=0.6}
    \draw (0,0) to[D] (2,0) node[nigbt, anchor=B] {} ;
\end{circuitikz}
\end{document}
