The G3SBA20-E3/51: The Vishay G3SBA20-/51 is a single-phase bridge rectifier in the standard GBU through-hole package, built with standard silicon technology. It delivers 2.3 A average rectified output (Io) and withstands 200 V peak reverse voltage (VRRM).
Forward drop and conduction loss
Maximum forward voltage is 1 V at 2 A forward current — at the rated 2.3 A average, conduction loss runs about 2.3 W.
Reverse leakage and blocking stability
Reverse leakage is specified at 5 µA maximum when the full 200 V blocking voltage is applied. At elevated junction temperature leakage doubles roughly every 10°C — at 125°C expect leakage in the tens of microamps, still negligible for most offline supplies and motor-drive DC bus precharge circuits.
