ROHM Offers the Industry’s Largest* Library of LTspice® Models at Over 3,500 by Adding SiC and IGBTs
Improves design convenience by allowing designers to incorporate power devices in circuit simulations
Willich-Münchheide, Germany, December 06, 2023 – ROHM has expanded the library of SPICE model lineup for LTspice® of its circuit simulator. LTspice® is 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 addition to the existing lineup of bipolar transistors, diodes, and MOSFETs, ROHM has added SiC power devices and IGBTs that increases its number of LTspice® models to more than 3,500 for discretes (which can be downloaded from product pages). This brings the amount of 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.

“The expansion of this tool enhances ROHM’s customer support sustainably,” states Aly Mashaly, Director Application and Technical Solution Center in Europe.

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 even seasoned engineers. To support these and other users, ROHM has expanded its library of LTspice® models for discrete products.

Besides product pages, ROHM has added a Design Models page in October that allows simulation models to be downloaded directly. 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.
