Silicon controlled rectifiers run up to
75A
Two new 75A-rated silicon controlled rectifiers expand the IR portfolio of discrete plastic SCRs, which now ranges from 10 to 75A, with voltages up to 1600V.
International Rectifier has released the 75A-rated 70TPS12 and 70TPS16 silicon controlled rectifiers (SCRs) in the Super-247 package The SCR is used in a multitude of applications, ranging from motor drive input bridges to line-frequency welding machines

International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
The new SCRs expand the IR portfolio of discrete plastic SCRs and now cover from 10 to 75A, with voltages up to 1600V, covering the most popular requests from industrial power designers.
Both 1200 and 1600V devices have excellent thermal performance.
For example, the junction-to-case thermal resistance of the 70TPS12 and the 70TPS16 is very low, with about 12% better thermal resistance than competing devices on the market, resulting in increased reliability.
IR's Super-247 package has lower thermal resistance (0.27C/W), and has the same power handling capability as the larger JEDEC TO-264 package.
However, the Super-247 has the same footprint as the common TO-247.
Other benefits include 1400V surge capability, which is useful for safe operation in case a fault condition exists, like a short circuit, and a maximum on-state voltage of 1.4V at 100A, for low power dissipation.
