Abstract: In a switching converter having an inductive load, a current may flow through the body diode of a transistor even though the gate of the transistor is being controlled to keep the transistor off. Then when the other transistor of the switch leg is turned on, a reverse recovery current flows in the reverse direction through the body diode. To reduce switching losses associated with such current flows, a gate driver integrated circuit detects when current flow through the body diode rises above a threshold current. The gate driver integrated circuit then controls the transistor to turn on. Then when the other transistor of the switch leg is made to turn on, the gate driver first turns the transistor off. When the gate-to-source voltage of the turning off transistor drops below a threshold voltage, then the gate driver integrated circuit allows and controls the other transistor to turn on.

Abstract: A power semiconductor device module includes a metal baseplate and a plastic housing that together form a tray. Power electronics are disposed in the tray. A plastic cap covers the tray. Electrical press-fit terminals are disposed along the periphery of the tray. Each electrical terminal has a press-fit pin portion that sticks up through a hole in the cap. In addition, the module includes four mechanical corner press-fit anchors disposed outside the tray. One end of each anchor is embedded into the housing. The other end is an upwardly extending press-fit pin portion. The module is manufactured and sold with the press-fit pin portions of the electrical terminals and the mechanical corner anchors unattached to any printed circuit board (PCB). The mechanical anchors help to secure the module to a printed circuit board. Due to the anchors, screws or bolts are not needed to hold the module to the PCB.

Abstract: An inverse diode die is “fast” (i.e., has a small peak reverse recovery current) due to the presence of a novel topside P+ type charge carrier extraction region and a lightly-doped bottomside transparent anode. During forward conduction, the number of charge carriers in the N? type drift region is reduced due to holes being continuously extracted by an electric field set up by the P+ type charge carrier extraction region. Electrons are extracted by the transparent anode. When the voltage across the device is then reversed, the magnitude of the peak reverse recovery current is reduced due to there being a smaller number of charge carriers that need to be removed before the diode can begin reverse blocking mode operation. Advantageously, the diode is fast without having to include lifetime killers or otherwise introduce recombination centers. The inverse diode therefore has a desirably small reverse leakage current.
