EMI/EMC Academy 8 Modules Interactive

EFT / Burst Immunity Testing
Surviving Fast Transient Bursts

Electrical Fast Transient (EFT) / Burst testing (IEC 61000-4-4) simulates the repetitive fast spikes produced when inductive loads switch — relays, contactors, motors. This course covers the waveform and levels, the test setup, how bursts couple into your product, and how to harden it, tying into the ESD, Surge and Pre-Compliance courses.

Core Modules

Work through these 8 modules in order. Each builds toward the capstone.

01
EFT / Burst — What It Is & Why It Exists
Where burst transients come from (inductive switching), why they are repetitive, and why they upset digital systems.
Lesson~25 min
02
The EFT Waveform, Bursts & Test Levels
The 5/50 ns spike, 5 kHz & 100 kHz burst timing, and the ±0.5–4 kV level classes for power and I/O ports.
Lesson~30 min
03
IEC 61000-4-4: Standard & Test Setup
The generator, coupling/decoupling network, capacitive coupling clamp, ground plane and how a compliant test is arranged.
Lesson~30 min
04
Coupling Paths & Failure Mechanisms
Common-mode injection, capacitive coupling, ground bounce and why bursts cause resets rather than damage.
Lesson~30 min
05
PCB & Circuit-Level Hardening
Filtering, TVS, series impedance, decoupling, reset/clock robustness and ground layout at the board level.
Lesson~35 min
06
Cables, Connectors & Filtering
Common-mode chokes, connector filtering, 360° shield bonds and where to place them for burst immunity.
Lesson~30 min
07
Firmware & System Robustness
Watchdogs, brown-out/reset supervision, error detection and recovery, and the A/B/C performance criteria.
Lesson~30 min
CS
Pre-Compliance, Debug & Case Studies
A bench burst-gen debug workflow, an interactive symptom→fix aid, and real case studies.
Capstone~40 min

Prerequisites

Foundational electronics (PCB layout, power/IO circuits, microcontrollers) and familiarity with the other EMC immunity tests. See the ESD and Surge courses for related transient-protection concepts.
