ZENER DIODE
Small Signal Zener Diode
General Description
These diodes small signal Zener diodes, fabricated in planar
technology. Miniature surface mount package is excellent for
hand-held and portable applications where is space is limited.
Features and Benefits
Silicon epitaxial planar diode
Low Zener impedance and low leakage current
Standard Zener voltage tolerance is 4.3%.
Full lead (Pb)-free device and RoHS compliant device
Available in “Green” device
Applications
Voltage regulator
