International Rectifier IRK.41 / IRK.56 Series Rectifier Datasheet
The IRK.41 and IRK.56 series are high‑voltage Add‑A‑pak™ power modules designed for regulated power supplies, lighting, motor‑speed control, UPS and battery chargers. They feature a thick aluminum metal die, double‑stick bonding, a copper baseplate for easy heatsink mounting, and UL E78996 approval.
The modules are available in a TO‑240AA case style, operate from –40 °C to 125 °C, and are rated for up to 1600 V repetitive off‑state voltage with on‑state average currents of 45 A (IRK.41) and 60 A (IRK.56). Thermal resistance is low (0.23 °C/W for IRK.41, 0.20 °C/W for IRK.56) and mounting torque of 5 Nm is recommended.
