Product Overview
G3SBA20 is presented as a single-phase bridge rectifier with an in-line bridge rectifier circuit configuration. It belongs to a datasheet series that also includes G3SBA60 and G3SBA80, with the G3SBA20 voltage ratings specified at 200 V repetitive peak reverse voltage, 140 V RMS voltage, and 200 V DC blocking voltage under the stated 25°C rating conditions.
The device uses a GBU package. The extracted outline data lists a body length of 0.880-0.860 in (22.3-21.8 mm), body height of 0.740-0.720 in (18.8-18.3 mm), and thickness of 0.310-0.290 in (7.9-7.4 mm). Thermal conditions are strongly tied to mounting: average output current is 4.0 A with the case mounted on an aluminum plate heatsink, or 2.3 A when mounted on the specified PCB copper pads.
Assembly and compliance details include matte tin plated leads, solderability per J-STD-002 and JESD 22-B102, solder dip at 275°C maximum for 10 s per JESD 22-B106, and UL recognition file E54214. The datasheet also states E3 and M3 compliance options, including RoHS-compliant and halogen-free/RoHS-compliant variants.
