A rectifier datasheet is a set of conditional statements, not a list of independent numbers. Two devices cannot be compared safely until current, waveform, temperature, pulse width, di/dt, PCB copper, heatsink, and guarantee type have been normalized. This guide provides that comparison method. It separates absolute maximum ratings from guaranteed electrical limits and typical curves, … Read more

Discrete power devices are semiconductor components used to switch, rectify or protect the flow of electrical power. Examples include power diodes, MOSFETs, IGBTs and thyristors. They work alongside controller chips and passive components in chargers, motor drives and power supplies, where their losses and operating limits affect heat, efficiency and reliability. The easiest way to … Read more

An SMPS, or switched-mode power supply, converts electrical power efficiently using a coordinated set of parts that rectify, switch, transform, filter, protect, and regulate voltage. The main components include the input filter, rectifier, bulk capacitor, switching transistor, controller IC, transformer or inductor, output rectifier, output filter, feedback network, and protection parts. Understanding each function helps … Read more

Select SMPS rectifier diodes by circuit role: Schottky, ultrafast and SiC compared, reverse-recovery loss worked out, and the datasheet checks that matter.

A MOSFET for a switching power supply must match the bus voltage, load current, switching frequency, and thermal limits. The best choice balances low RDS(on), low gate charge, adequate voltage margin, and package thermal performance. In SMPS designs, the right device improves efficiency, reduces heat, and increases reliability. Last updated: October 11, 2026 Key Takeaways … Read more

A switching power supply EMI filter design reduces conducted noise, improves EMC compliance, and protects the power line from switching spikes. The best design starts by identifying whether the noise is differential mode or common mode, then choosing the right LC, pi, or common-mode choke network, and finally validating the result with measurement and layout … Read more
