Rectifiers are offered in a high voltage TO-263 package

Two high voltage rectifiers with 2.2Kv ratings, in a D2-HV (High Voltage TO-263) package, have been announced by IXYS. The products introduced are the DNA30EM2200PZ and DNA30E2200PZ. The D2-HV Pak is a package solution that offers higher creepage spacing thus enabling higher voltage power semiconductors to be used as SMDs.

DNA30EM2200PZ and DNA30E2200PZ are single rectifiers offering a 30A rating at case temperatures of Tc = 140 degrees C and a 2200V reverse blocking capability. The “EM” version has the anode connected to the tab and the cathode connected to both pins of the package. For the “E” version one pin (and the tab) is connected to the anode and the other pin is the cathode.

“The market demands smaller footprint solutions for high voltage power semiconductors. By going to higher voltages, the device can deliver more power to the load with less current, thus reducing the conduction losses in copper wires in power control circuits; therefore, thinner copper conductors or traces on PCB circuits can be used. These SMDs improve energy efficiency, reduce cost, reduce size and reduce weight when used in power electronics,” states Dr. Elmar Wisotzki, General Manager of IXYS GmbH.

SMDs are preferred as lower cost alternatives to modules and to other bulkier discrete components in integrated power designs. Fully automated PCB SMD assembly equipment can be used which reduces the manufacturing cost of high voltage power products. The new IXYS D2-HV Pak platform offers the standard footprint, but with compliance to the high voltage creepage specifications.

For the D2-HV Pak, the creepage distance between the terminal to the copper of the backside is greater than or equal to 4.70 mm. In addition to industrial power control applications, these devices target other 1.2KV to 2.2kV power supplies, UPS, renewable energy, motor drives and medical applications.
