The R4220TS is a standard recovery rectifier diode from Microchip Technology, designed with reverse polarity (anode to case). It delivers a high average rectified current of 125 A and a maximum forward voltage of 1.2 V at 200 A. The diode has a standard reverse recovery time greater than 500 ns at 200 mA, making it suitable for power rectification applications where fast switching is not required.
The device is mounted via a stud mount in a DO-205AA (DO-8) package, which is a common high-current package for industrial and commercial power supplies. It operates over a wide temperature range of -65°C to 200°C, ensuring reliability in harsh environments. The part is listed as RoHS3 compliant, REACH unaffected, and has an MSL of 1, though these compliance claims are unverified.
This rectifier is typically used in high-current DC power supplies, battery chargers, motor drives, and welding equipment. The reverse polarity configuration allows the anode to be connected to the heatsink, simplifying thermal management in certain designs.
