Diodes unveils first super barrier rectifier
Diodes Incorporated
SBR10U200P5
Diodes Incorporated has introduced the first in a series of high-voltage super barrier rectifiers (SBRs) packaged in the thermally efficient, compact PowerDI5 package.
The thermal resistance of the proprietary PowerDI5 package enables the SBR10U200P5 to deliver twice the power density from a PCB footprint that is 40 per cent smaller.
The SBR10U200P5, a leaded 10A rectifier rated up to 200V, delivers a low forward volt drop (VF) of 0.7V at 10A rated current and at a junction temperature of 125C.
Coupled with an off-board package height of 1.1mm - half that of Dpak - the SBR10U200P5 enables designers to reduce the form factor and increase the power density of compact power supplies for end applications such as notebook power adapters, universal chargers and telecom power supplies.
The device's patent-pending package structure enables higher-power dissipation and surge capabilities in a compact, low-profile package.
This results in a maximum rated junction temperature of 175C and an avalanche rating 50 per cent greater than that offered by a competing Schottky diode solution packaged in Dpak, according to Diodes.
Accordingly, the SBR10U200P5 facilitates snubber circuits to be removed from power-supply outputs, enabling designers to reduce end product cost and simplify their designs.
The features of the SBR10U200P5 make it suitable for use as an output diode in power-supply output stages, as a catch diode in Buck regulator circuits, as a freewheeling diode in motor drive circuits and as a boost diode.
