Hello ST Team and Community,
I am currently testing the IGBT STGP10M65DF2 in PSpice to verify the Eon (Turn-On Energy) and Eoff (Turn-Off Energy) parameters based on the datasheet. My test conditions strictly follow the datasheet: Tj = 175°C, Rg = 22Ω, and all other parameters are identical to those specified. I calculated Eon and Eoff using IEC 60747-9, but my simulation results show that Eon is smaller than the datasheet value, while Eoff is larger. Additionally, my results closely resemble those obtained under high stray inductance conditions, even though my setup follows the datasheet parameters.
My Questions:
1. Could there be an issue with the datasheet values for Eon and Eoff?
2. What standard/methodology does ST use to calculate Eon and Eoff in the datasheet?
3. Does the Eoff calculation in the datasheet explicitly consider tail current?
I would really appreciate any insights from the ST team or experienced community members. Please let me know if you need any additional data to assist with the analysis.
