This series of Silicon Zener Diodes, covering a voltage range from 3.3 to 200 Volts, offers high peak reverse power dissipation, high reliability, and low leakage current. They are designed for general purpose use and are Pb/RoHS free. The diodes are housed in a DO-41 molded plastic case with UL94V-O rated flame retardant epoxy and axial leads solderable per MIL-STD-202, method 208. The color band denotes the cathode end, and any mounting position is acceptable.
