If your circuit needs to adjust from an AC to DC voltage use a Schottky diode STPS30M80CR rectifier from STMicroelectronics. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This rectifier has a maximum operating temperature of 175 °C. It is made in a dual common cathode configuration. Its peak non-repetitive surge current is 220 A, while its maximum continuous forward current is 30 A.
