Lesson 8/1747%
MODULE 08

Component Selection Criteria

A systematic selection methodology: derive the isolation requirement from the application, filter by speed and output type, size CTR with lifetime margin, respect temperature and package constraints, and optimize cost across volume scenarios — ending in a reusable selection worksheet.

Learning Objectives

After completing this module, you will be able to:

Derive isolation requirements from system architecture
Filter device families by speed and output needs
Apply CTR margin methodology for lifetime reliability
Trade off package, temperature, and certification constraints
Optimize selections for cost at volume

Planned Topics

Isolation requirements
Speed requirements
CTR selection
Output type selection
Temperature range
Package selection
Cost optimization

Reserved Sections

This module will follow the same interactive format as Module 1:

Interactive animations

Animated diagrams and simulations for this module are in development.

Engineering calculators

Module-specific design calculators will appear here.

Design examples

Worked examples with full component values are planned for this section.

Knowledge check

Multiple-choice, true/false, and scenario exercises will be added.

Downloadable resources

PDF notes, reference tables, and checklists will be provided.

While you wait: Module 1 — Introduction to Optocouplers — is fully available, including animations, the CTR and isolation calculators, and a complete knowledge check. Start there →
