1N5261DUR-1 Datasheet



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.
