If your circuit needs to adjust from an AC to DC voltage use a switching diode STTH16R04CT 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 minimum operating temperature of -40 °C and a maximum of 175 °C. It is made in a dual common cathode configuration. Its peak non-repetitive surge current is 120 A, while its maximum continuous forward current is 16 A.
