Product guide

Diodes, transistors, MOSFETs and IGBTs

Discrete and power semiconductors include diodes, bridge rectifiers, transistors, MOSFETs, IGBTs, thyristors and triacs. Circuit function, drive requirements and thermal behaviour guide selection. When comparing part numbers, package, pinout and parameters under the intended operating conditions must be reviewed before qualifying a replacement.

Products and technical requirements

I support engineers and purchasing teams in clarifying the requirement, identifying relevant products and discussing the technical and commercial aspects with the partner. Share your application and an existing datasheet where available: a proposed alternative still requires validation in your design.

Partner and product-line references

The relevant partnership for this family is DSPM TLC. My role and the official company links are described on the partners page.

Brands listed on this website for the relevant product area:

  • KEC

    Diodes and rectifiers, bipolar transistors, MOSFETs and IGBTs; amplifiers, comparators and power management ICs.

  • Leapers Semiconductor

    SiC power modules, hybrid SiC/Si modules and IGBT modules.

  • Innoscience

    High- and low-voltage GaN HEMTs; gate drivers and controllers.

  • Topdiode

    Ceramic, film, electrolytic and tantalum capacitors; diodes, rectifiers and discrete semiconductors.

Availability, exact specifications and supply conditions are assessed against the requested part number and project.

Documents to prepare

Share the information already available and identify anything still to be defined. Attach documents in the enquiry form; agree sharing arrangements first for confidential files.

  • Full manufacturer part number and reference datasheet.
  • Quantities, schedule and whether you need the same part or an alternative.
  • For alternatives: circuit function, package, pinout and design constraints.

The form accepts up to 3 files: 2 MB each and 3 MB in total. For larger documents, use the email contact.

Questions before your enquiry

Should I distinguish a price enquiry from an alternative search?

State the objective at the outset. A quotation needs a part number and quantities; an alternative also needs application constraints to compare against the DSPM product line.

Does proposing an alternative confirm equivalence?

No. Technical and commercial selection helps identify candidates; compatibility and final qualification must be validated in the design and operating conditions.
