Lesson 6/1735%
MODULE 06

Optocoupler Parameters

Every number on the datasheet that matters, treated quantitatively: CTR and its dependencies, the full isolation voltage family, forward-current limits, propagation delay and pulse-width distortion, common-mode transient immunity (CMTI), and thermal behavior.

⏳ Coming Soon — content in development

Learning Objectives

After completing this module, you will be able to:

Define and apply every key optocoupler parameter
Compute worst-case CTR across current, temperature, and life
Interpret CMTI ratings for switching converter environments
Budget power dissipation and junction temperatures
Build a parameter checklist for design reviews

Planned Topics

CTR in depth
Isolation voltage family
Forward current limits
Propagation delay and distortion
CMTI
Thermal characteristics
Power dissipation

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 →
