DESCRIPTION:
The CENTRAL SEMICONDUCTOR 1.5 Watt Surface Mount Silicon Zener Diode is a high quality, well
constructed, highly reliable component designed for use in all types of commercial, industrial, entertainment,
computer, and automotive applications where small size is required. The SMA case occupies 30% less
board space than the SMB case. To order devices on 12mm Tape and Reel (5000/13" Reel), add TR13
suffix to part number.
