Tip32c Spice Model Direct

Before analyzing the model, let us establish the physical device. The TIP32C is a silicon PNP epitaxial-base transistor manufactured in a plastic TO-220 package. Its key characteristics include:

(using this model): V_CE(sat) ≈ 1.15V at 25°C.

Before diving into the code, it is essential to understand what we are modeling. The TIP32C is part of the TIP31/TIP32 series. While the TIP32A and TIP32B are common, the is the highest voltage grade in the family, typically featuring a $V_CEO$ of 100V. tip32c spice model
