The ZMM5221B THRU ZM5267B series are 0.5W silicon planar power zener diodes designed for general-purpose applications. 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 feature a JEDEC MINI-MELF glass case with solderable terminals per MIL-STD-202, Method 208. The color band denotes the cathode end. They are suitable for any mounting position and have a weight of approximately 0.031 grams.
