D4020L Description

Short technical summary and product information.

The D4020L is a standard recovery silicon rectifier diode from Littelfuse’s Dxx20L series, designed for DC phase control applications with motor loads. It offers a peak repetitive reverse voltage of 400V and an average rectified current of 12.7A at a case temperature of 80°C. The RMS forward current is 20A. The forward voltage is typically 1.6V at 12.7A and maximum 1.6V at 40A. The reverse recovery time is typically 4µs. The device can withstand a non-repetitive peak surge current of 300A (60Hz single half-cycle) and has an I²t rating of 374 A²s. The operating junction temperature ranges from -40°C to 125°C. The TO-220-3 isolated tab package allows for through hole mounting and provides electrical isolation, enabling common anode or common cathode configurations. Typical applications include AC to DC solid-state switches for industrial power tools, exercise equipment, white goods, and commercial appliances. The device is RoHS compliant and features glass-passivated junctions for reliability.
