Family datasheet spanning the 1N4001 through 1N4007 rectifiers, a 43.0 KB PDF listed in the schematic section. One table usually lists each grade from 50 V up to 1000 V reverse voltage, all at 1 A forward current. That makes it a convenient reference for comparing grades and confirming that a higher rated part can replace a lower one in the same footprint. Technicians also use it for surge current, forward drop and cathode band orientation when servicing power circuits.
