No hot-air station, no reflow profile. The three leads are spaced on a standard 0.1-inch pitch, so it fits protoboard and legacy PCB layouts without a footprint change. Orientation is obvious: the flat face of the TO-92 body marks the front, and the pinout (cathode, anode, reference from left to right when the flat faces you) is consistent across the whole TL431 family. If you carry a few of these in your field kit, you can fix a dead reference rail in a power supply or a failed threshold comparator in a controller without bringing the board back to the bench.","metaTitle":"TL431ILPE3 Shunt Reference, Adjustable 2.495V to 36V","metaDescription":"TL431ILPE3 adjustable shunt voltage reference, ±2.2% tolerance, 100 mA output, TO-92-3 through-hole.
