AID AI Datasheet™ for WL-OCPT Series 816
This revamped AI Datasheet converts the static WL-OCPT PDF datasheet into an interactive component-level design-in layer. It preserves the baseline specifications and order-code system while adding queryable chart data, an operating-point estimator, ordering guidance, and mechanical/assembly visuals.
Spec-groundedUses datasheet limits: 5000 VRMS isolation, 80 V VCE, 60 mA LED current, and CTR bins from 50% to 600%.
Chart-accurateCharts are rendered from the supplied spreadsheet digitization, not from manually approximated curves.
Design-in focusedEngineer can compare CTR bin, IF, VCE, temperature, load resistance, switching time, and cost guidance in one file.
What changed in this revamp
- Rebuilt the chart engine with the fixed updated spreadsheet data for all 17 charts, including corrected Chart 7 collector-current data.
- Added the order-code decoder image and expanded ordering table for all 25 orderable variants.
- Added the schematic, product package image, dimensions, hole/land pattern, and soldering profile visuals in the correct sections.
- Added an estimator that combines CTR-vs-IF and CTR-vs-temperature curves into a practical operating-point view.

Operating-Point Design Estimator
This estimator is a practical AID layer built from the accurate datasheet chart data. It does not replace validation; it gives the design engineer a fast way to see combined CTR, collector current, saturation voltage, and switching-time trends at a proposed operating point.

Model Boundaries
- All 17 interactive charts are rebuilt from the fixed updated “Accurate chart data - coupler.xlsx” spreadsheet and trace back to the datasheet chart pages.
- The estimator is an interpolated design-in aid. It is not a replacement for the official datasheet limits, reliability qualification, or bench validation.
- Safety-critical applications require the customer's own verification and Würth approval where applicable.
Why this AID layer is useful
Traditional PDF datasheets show many static curves. This AID version lets the designer query and connect those curves: CTR bin selection, LED drive current, collector voltage, temperature behavior, switching load, package choice, board pattern, soldering limits, and cost context. That is the practical design-in value of the AID AI Datasheet™ layer.
