TOSHIBA CORPORATION has been publishing MOSFET device SPICE models for PSpice® and LTspice® on the Web. In addition to those currently being published, Toshiba has begun publishing high precision SPICE models with high reproducibility of transient characteristics.
While the SPICE models we have been publishing (called the G0 model in Toshiba) are standard device models and are suitable for function checking because of their fast computing speed, the SPICE models we have started publishing this time (also called the G2 model) enhance the reproducibility of the high current region characteristics of ID-VDS curve and the voltage-dependent characteristics of the parasitic capacitance, allowing us to simulate the switching with higher accuracy closer to actual measurement.
The following shows the actual measurement of R-Load switching turn off waveform of the low voltage MOSFET device and L-load switching turn off waveform of the mid to high voltage MOSFET device, and the simulated waveforms of the G0 model and G2 model, respectively.
<R load switching turn off waveforms>
<L load switching turn off waveforms>
Thus, G2 model reproduces the waveform near actual measurement, and it becomes possible to predict power conversion efficiency and noises such as EMI, more correctly on a desk, it improves working efficiency, and contributes to shortening development period.
Currently, this has been released to the public for some of our low voltage MOSFET and in-vehicle MOSFET products, but we plan to successively expand this range to other products, including mid to high voltage MOSFET products.
Please use G0 model to check the operation without spending a long time, and use the G2 model to know characteristics accurately. Please be sure to try the G2 model as it will be effective for more accurate simulations such as loss characteristics.
More information about the G2 model can be found in this application note.
Please refer to this page for the products currently being released to the G2 model.
G0 and G2 models can be downloaded from above linkage destination. If you select the desired model and click here, the zip file with the following name will be downloaded.
For PSpice model: (product name)_PSpice_(registration date).zip
For LTspice models: (product name)_LTspice_(registration date).zip
If you unpack it, you will find a total of four files in the unpacking folder: library files and symbol files for G0 and G2 model each.
(Product name)_G0_00_PSpice_revX.lib G0 model library file for PSpice
(Product name)_G0_00_PSPICE_REVX.OLB G0 model symbol file for PSpice
(Product name)_G2_00_PSpice_revX_enc.lib G2 model library file for PSpice
