IR Intros 40L15CW Family of Schottky DiodesMarch 10, 1999 by Jeff Shepard
International Rectifier (IR, El Segundo, CA) introduced the 40L15CW family of Schottky diodes optimized specifically for OR'ing applications in high-reliability power supplies. According to IR, the new diodes match competitive devices in all specifications, but add 150 degrees C maximum junction temperature at no extra cost. Operating the device junction at a higher temperature is claimed to allow a further reduction in forward voltage drop for greater efficiency.The common cathode arrangements in the new diodes makes them suitable for use in systems with power levels of 20A when used in the common-cathode mode or 40A when the internal diodes are paralleled. The 40L15CW is packaged in a TO-247 packaged and is priced under $1 in high volumes.
