, LL957B thru MINI-MELF-SMD 0.5 Watt Zener Diodes LL992B ~ a .. Use Advantages Full performance replacement for plastic SOT-23 zener diodes. Occupies the same footprint as plastic SOD 123 or SMA, no PC board rework. MELF vs. SMA - possible savings are as much as 50%. Compatible with all major automatic pick and place SM mounting equipment. May be used on ceramic boards along with high temperature IR solder reflow. For use in stabilizing and clipping circuits, where real surge protection is a necessity. MIL-S-19500/117 "UR" DO-213AA SMD approvals, see list for bold V types.
