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 …
MOSFET Thermal Management Tips for DIYers
The Problem: MOSFETs Overheating in Circuits MOSFETs are crucial in switching applications, but they heat up fast when handling high current. Without proper thermal management, overheating can lead to inefficiency, instability—or worse, component failure. 
The Solution: Heatsinks, Thermal Pads, and PCB Design The simplest fix is adding a heatsink or …
SMPS High-Density Layout Design – Tips for Compact Power!
The Problem: Crowded SMPS = Noisy Power When designing high-density SMPS (Switched Mode Power Supply) circuits, space constraints often force components close together. This can lead to electromagnetic interference (EMI), voltage instability, and heat buildup—especially problematic in compact IoT or embedded systems.

MOSFET Switching Frequency Guide – Made in India Tips
The Problem: Why MOSFET Switching Frequency Matters When using MOSFETs in power circuits—like motor drivers, LED dimmers, or inverters—switching frequency is how fast your MOSFET turns on/off. If it’s too fast, heat builds up due to switching losses. If it’s too slow, performance drops. Beginners often overlook this, leading to burnt components or …

MOSFET Safe Operating Area Tips for Reliable Design
The Problem: Exceeding the Safe Operating Area (SOA) When working with MOSFETs, many hobbyists overlook one crucial spec: the Safe Operating Area (SOA). Exceeding it can quickly destroy your device. The SOA defines the limits of voltage, current, and power a MOSFET can handle at the same time. Ignoring this often results in …

Reverse Current Protection in LED Lighting
The Problem: Reverse Current in Lighting Circuits Reverse current happens when power flows backward through your LED or lighting driver circuit—especially in multi-supply or backup battery scenarios. This can damage components, cause flickering, or reduce lifespan. The Solution: Add Reverse Current Protection The simplest fix? Use a Schottky diode or …
SMPS Voltage Regulation Guide for Prototypers
The Problem: Unstable SMPS Output Voltage Switched-mode power supplies (SMPS) are efficient, but poor voltage regulation can lead to unreliable circuit performance, especially when the load varies. If your output voltage drops or spikes, your microcontroller or sensors might behave unpredictably—or fail! The Solution: Optimize Feedback & Filtering SMPS uses …
MOSFET Reverse Recovery Tuning Made Easy
The Problem: Understanding Reverse Recovery in MOSFETs When switching MOSFETs, especially in high-frequency circuits like SMPS or inverters, reverse recovery of the body diode can lead to voltage spikes, heat, and EMI. This happens when the diode doesn’t turn off instantly, causing current to flow briefly in the wrong direction. The …
