Incorporating them into LTSPICE is easy using an .include statement As far as I know the only depletion mode FETs in the standard LTSPICE libra= ry are JFETs. Best regards, Bob ________________________________________ From: piclist-bounces@mit.edu on behalf of Jim Sent: Tuesday, January 7, 2020 11:55 AM To: Microcontroller Public Subject: [EE]: LTSpice Question All, I have a need to simulate a circuit using a Depletion Mode MOSFET using LTSpice. I have looked at the list of MOSFETs included in the application, but I don't see any Depletion Mode FETs. Does anyone have any idea what part number in LTSpice could be a Depletion Mode MOSFET? Or does anyone have a model of an N Channel Depletion Mode MOSFET that will run under LTSpice? The parameters of the particular part number aren't an important issue at this time. I just need a functional model for a quick proof of concept for a new circuit for a new product at work. I can't elaborate on this further at the moment, but later, if all works out, I'll let everyone know that is interested what the circuit is intended to do, and if it does what it's supposed to. Anyway, if anyone knows if any of the MOSFET part numbers listed in LTSpice are Depletion Mode FET's, please let me know.
