Datasheet for the 1N5333B in PDF form, 87.5 KB, indexed under schematics. The 1N53xx numbers of this range are generally zener diodes, with the B suffix normally denoting a tolerance grade, so check the document for the exact zener voltage and tolerance. Technicians use it to confirm the regulation voltage and power rating of a clamp or reference diode before replacement. Any PDF viewer opens it. Measure the original in circuit carefully, and match both voltage and wattage when choosing a substitute.
