The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more. This wid… ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop?

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has launched a 6.5 kV power module that features IGBT and freewheeling diode functionality integrated into a single chip.
