Is this something the company will provide? If not, which Spice model should be used to calculate the correct characteristics for this part using the datasheet entries? Are there any other tools that can be used to extract the values for the model?</P></BODY></HTML> Wed, 11 Mar 2020 20:39:17 GMT https://community.nxp.com/t5/Other-NXP-Products/Spice-Model-Files-For-BFU768F/m-p/1020120#M8649 derekdszymanski 2020-03-11T20:39:17Z Re: Spice Model Files For BFU768F https://community.nxp.com/t5/Other-NXP-Products/Spice-Model-Files-For-BFU768F/m-p/1020121#M8650 <HTML><HEAD></HEAD><BODY><P>BFU768F is a variance of BFU760F (selection optimized to operate at 10.8mA).
