MOSFET Avalanche Protection Tips
The Problem : MOSFETs are powerful and efficient switches, but when used with inductive loads (motors, solenoids, relays), they’re vulnerable to avalanche breakdown. This occurs when a sudden voltage spike—caused by inductive energy—exceeds the MOSFET’s drain-source breakdown voltage (V<sub>DSS</sub>), damaging the part. 
The Solution : Use a freewheeling diode (also …
Reverse Voltage Protection for 48V Rails
The Problem : Reverse voltage can instantly damage sensitive components on your 48V power rail—especially in industrial or robotics applications where connectors might be inserted incorrectly. For beginners and prototypers, this can mean blown ICs or fried PCBs. The Solution : To avoid this, use reverse polarity protection. One of the most efficient …
SMPS Voltage Spike Mitigation Tips for Indian Makers
The Problem: Voltage Spikes in SMPS Circuits Switched Mode Power Supplies (SMPS) are efficient but can generate high-frequency voltage spikes during switching.

MOSFET ESD Robustness Tips for Indian Prototypers
Electrostatic discharge (ESD) is one of the most common causes of MOSFET failure—especially in prototyping and handling stages. A simple static shock from your hand can silently damage the gate, leading to unpredictable behavior or total failure. 
The Problem: Static Electricity Kills MOSFETs MOSFET gates are extremely sensitive. Even 100V of static …
MOSFET Load Dump Protection – Safe Power Handling (India)
The Problem In automotive and industrial circuits, a load dump happens when a large load like a battery is suddenly disconnected. This causes a voltage spike (up to 60V in a 12V system!) that can instantly damage sensitive electronics. It’s a common but preventable issue in power electronics. The Solution …
