IR Intros High-Voltage, High-Current 105PF40T Diode

International Rectifier Corp. (IR, El Segundo, CA) introduced its new 105PF40T 400 V, 105 A diode in a plastic DO-5 package for heavy-duty, industrial applications such as arc welders and storage battery chargers. The single-hole mount provides flexibility for multiple diode assemblies, such as bridge rectifier circuits.

The glass-passivated silicon chip in the new diode is housed in a threaded, stud-mount plastic package, designed to simplify heatsink mounting. It features low maximum peak forward voltage of 0.98 V at 200 A (typical) and a thermal resistance of 0.25 °C/W. Competing devices have higher thermal resistances from 0.35 °C/W to 0.40 °C/W.

The 105PF40T is now available. Pricing begins at $4 each for 1,000-unit quantities. Pricing is subject to change.
