IGBT vs MOSFET: How IGBTs Work and How to Select Them
Choosing between an IGBT and a MOSFET starts with the converter’s current and switching events. An insulated gate bipolar transistor combines a voltage-controlled insulated gate with bipolar conduction in its power path. It can be useful in power converters and motor drives, but its turn-off behavior, gate drive and associated diode must fit the circuit. … Read more
Wide Bandgap Semiconductor Sourcing: SiC Diodes and MOSFETs
Wide bandgap semiconductor sourcing starts with the power stage’s requirements, not with a preference for SiC. A silicon carbide Schottky barrier diode is a rectifier; a SiC MOSFET is a controlled switch. Specify the voltage, current waveform, switching conditions, cooling and qualification needs before comparing devices, samples and commercial terms. This guide focuses on SiC … Read more
SiC MOSFET vs Silicon MOSFET: Losses, Gate Drive and Selection
Choosing a SiC MOSFET over a silicon MOSFET makes sense when its electrical behavior helps the complete converter meet loss, size or operating requirements. SiC can offer useful advantages in suitable higher-voltage switching stages, but a material name alone does not establish better efficiency. Compare the actual devices at the same voltage, current, temperature and … Read more
How to Choose the Right Power Rectifier: Ratings and Losses
To choose the right power rectifier, first identify its circuit role, then check reverse voltage, the full current waveform, switching behavior and cooling. A diode that matches the load current can still be unsuitable if it cannot withstand the reverse peak, startup pulse or temperature in the finished assembly. The selection process below works for … Read more
Transient Voltage Suppressor: Protect Electronics From Lightning, ESD, and Switching Surges
A TVS diode clamps lightning, ESD and switching surges before they reach sensitive circuits. Learn how standoff voltage and clamping voltage are sized.
