STP2045CTC Schottky Rectifier Diode TO220 20A 45V 2045

The STP2045CTC is a 45V, 20A through-hole power Schottky barrier rectifier diode manufactured by STMicroelectronics for switch-mode power supplies, high-frequency DC-to-DC converters, and polarity protection applications. Housed in a standard through-hole TO-220AB molded plastic package, this discrete component features a dual common-cathode configuration designed to handle high currents and minimize conduction losses in output rectification circuits. It operates with a maximum repetitive peak reverse voltage of 45V and an average rectified forward current of 20A total (10A per diode leg) while carrying the package top-side marking code "STPS2045CT". Engineered with a maximum forward voltage drop of 0.57V at a 10A test current per leg, negligible switching losses, and high avalanche capability, this robust device delivers reliable performance across an operating junction temperature range from minus 65 to plus 175 degrees Celsius.
