ROHM expands library of LTspice models to over 3500 by adding SiC and IGBTs
Japan’s ROHM has expanded its lineup of SPICE models for the LTspice circuit simulator, increasing its number of LTspice models to more than 3500 for discretes (which can be downloaded from product pages).
In addition to the existing lineup of bipolar transistors, diodes and MOSFETs, ROHM has added silicon carbide (SiC) power devices and insulated-gate bipolar transistors (IGBTs) to the library. This brings the coverage of LTspice models on ROHM’s website to over 80% of all products, providing greater convenience to designers when using circuit simulators that incorporate discrete products, now including power devices. LTspice is also equipped with circuit diagram capture and waveform viewer functions that make it possible for designers to check and verify in advance whether the circuit operation has been achieved as designed.
In recent years, the increasing use of circuit simulation for circuit design has expanded the number of tools being utilized. Among these, LTspice is an attractive option for a range of users, from students to seasoned engineers at well-known companies.
Besides product pages, ROHM added a Design Models page in October that allows simulation models to be downloaded directly, supporting LTspice and other tool environments. Documentation on how to add libraries and create symbols (schematic symbols) is also available to facilitate circuit design and simulation execution.
Going forward, ROHM will continue to contribute to solving circuit design issues by expanding the number of models compatible with various simulators while providing web tools such as ROHM Solution Simulator to meet growing customer needs.
