The document compares the simulation results of SPICE models from two companies, Bee Technologies and Rohm, for a DTC144EE transistor. The Bee Technologies model more accurately simulates the transistor's ON and OFF characteristics, current gain, and output voltage compared to the datasheet specifications with errors within 5% for most measurements. The Rohm model has larger errors in simulating the transistor parameters, with some exceeding 10% difference from the datasheet values.
