Vishay

Applications may require customization involving package or mounting requirements, optical characteristics, electrical interfaces, or integration into larger assemblies. From changing passive element placement and utilizing high accuracy AuSn patterning to transitioning component design to our thin film platform, Vishay’s engineering team determines how an existing optoelectronic platform can be adapted or a purpose-built design delivered to meet customer performance requirements.

Two Ways to Work with Our Optoelectronics & Isolators Team

Re-configure an existing optoelectronics & isolators

Start from one of Vishay's existing module families and work with our engineers to adapt it to your specific requirements. Faster to qualify, lower NRE cost, and suitable for designs where a standard topology gets you most of the way there.

Common modification requests

Re-configured pinout or terminal configuration
Non-standard die combinations within an existing package
Modified substrate material for thermal performance
Alternative isolation voltage or current rating
Package labeling or marking to customer specification

Request a Re-configuration Consultation

Design an application-specific optoelectronics & isolators from scratch

When your application demands a topology, form factor, or performance envelope that no existing module can meet, our engineering team designs from the ground up. From initial spec through prototype validation and into volume production.

Common new-design requests

Multi-die assemblies with mixed semiconductor technologies
Application-specific transfer-molded or open-frame packages
Application-specific thermal management integration
High-reliability designs for automotive, aerospace, or medical
SiC-based topologies for EV, solar, or industrial inverter applications

Your design stays yours.

Custom Service designs developed through this program are created exclusively for you. We do not add customer-specific designs to our general product catalog or make them available to any other party. Your requirements, your specifications, and your intellectual property remain confidential throughout every stage of our engagement.

Here is what the experience looks like from your side.

You submit a request

A brief description of your project is all that is needed to start. Our team will ask for more detail once we have reviewed what you have shared.

An engineer reaches out

A member of our engineering team will contact you directly to discuss your requirements, ask questions, and assess whether your project is a good fit for our capabilities.

Custom IR Receiver Module for Multiple RC Codes

Challenge

Our customer was evaluating IR receiver modules for a new consumer application design. They required a device that would minimize component counts, costs, and board space requirements, while increasing manufacturability. Furthermore, the module needed to be capable of handling multiple remote control codes between system frequencies of 38 kHz and 56 kHz. However, standard IR receivers are optimized for one frequency, typically 36 kHz or 38 kHz. While they can receive remote control signals for other frequencies, their bandwidth is limited to signals from 26 kHz to 50 kHz, as illustrated by the blue line in the graph below.
