The 1N5221BUR thru 1N5281BUR series of 0.5 watt Zener Voltage Regulators provides a surface mount equivalent to the popular JEDEC registered 1N5221B to 1N5281B for 2.4 to 200 volts in standard 5%
tolerances as well as tighter tolerances identified by different suffix letters on the part number. These are also available with an internal-metallurgical bond option by adding a “-1” suffix (see separate data sheet). Microsemi also offers numerous other Zener products to meet higher and lower power applications.
