The ZMM52 Series are silicon planar power zener diodes designed for general-purpose regulation. They offer standard zener voltage tolerances of 5% (with a "B" suffix) and 10% (with an "A" suffix), with other tolerances available upon request. These diodes are housed in a JEDEC MINI-MELF glass case, making them suitable for various electronic applications where stable voltage reference is required.
